1.
Conifers are
Correct Answer
B. Vascular plants
Explanation
Conifers are vascular plants because they have specialized tissues that transport water, nutrients, and sugars throughout the plant. This vascular system consists of xylem, which carries water and minerals from the roots to the rest of the plant, and phloem, which transports sugars produced during photosynthesis to other parts of the plant. Unlike nonvascular plants, such as mosses and liverworts, conifers have well-developed roots, stems, and leaves, which further support their classification as vascular plants.
2.
Flowering plants
Correct Answer
A. Produce seeds
Explanation
Flowering plants are able to reproduce by producing seeds. Seeds are the result of fertilization between the male and female reproductive structures of the plant. They contain an embryo and are surrounded by a protective seed coat. This method of reproduction allows flowering plants to disperse their offspring over long distances and ensures the survival of their species.
3.
Tubelike cells that carry food from the leaves to other parts of the plant are called
Correct Answer
B. pHloem
Explanation
Phloem is the correct answer because it is a type of tissue in plants that transports food, such as sugars and other organic compounds, from the leaves to other parts of the plant. It consists of tubelike cells that form a network throughout the plant, allowing for the distribution of nutrients to support growth and metabolism.
4.
Liverworts grow
Correct Answer
B. Flat and close to the ground
Explanation
Liverworts grow flat and close to the ground. This means that they have a low profile and are in direct contact with the soil or substrate they are growing on. This adaptation allows them to absorb moisture and nutrients efficiently from the ground. Growing flat also helps liverworts to maximize their surface area for photosynthesis, as they rely on sunlight for energy. Additionally, growing close to the ground provides protection from harsh weather conditions and reduces the risk of desiccation.
5.
Turpentine, paper, and fuels (coal) are supplied by
Correct Answer
B. Conifers
Explanation
Conifers are the correct answer because they are a type of plant that includes trees such as pines, spruces, and firs. These trees produce resin, which can be distilled to obtain turpentine. Additionally, conifers are used to make paper and are a source of fuel, particularly coal. Therefore, conifers are responsible for supplying turpentine, paper, and fuels like coal.
6.
The process that best separates plants from animals is
Correct Answer
C. pHotosynthesis
Explanation
Photosynthesis is the process that best separates plants from animals. While both plants and animals respire and reproduce, only plants have the ability to perform photosynthesis. Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into glucose and oxygen. This unique process allows plants to produce their own food, while animals rely on consuming other organisms for energy. Therefore, photosynthesis is the key characteristic that distinguishes plants from animals.
7.
Structures that anchor vascular plants and take in water and minerals are
Correct Answer
C. Roots
Explanation
Roots are structures that anchor vascular plants and take in water and minerals from the soil. They play a crucial role in the absorption of water and nutrients, providing support to the plant, and storing food reserves. Roots also help in preventing soil erosion by binding the soil particles together. Unlike stems, leaves, and flowers, roots are primarily responsible for the plant's uptake of water and minerals, making them the correct answer in this context.
8.
Nonvascular plants that are flat, leaflike, and grow very close to the soil are
Correct Answer
C. Liverworts
Explanation
Liverworts are nonvascular plants that are flat, leaflike, and grow very close to the soil. They belong to the phylum Marchantiophyta and are characterized by their small, lobed leaf structures. Unlike vascular plants, liverworts do not have specialized tissues for transporting water and nutrients, which is why they typically grow in moist environments. Their close proximity to the soil allows them to absorb water and nutrients directly from the ground. Therefore, liverworts are the correct answer in this case.
9.
These plants may live on rocks and break the rocks down into soil.
Correct Answer
D. Mosses
Explanation
Mosses are able to live on rocks and break them down into soil because they have the ability to retain water and nutrients. They have rhizoids that anchor them to the rocks and absorb water and minerals from the surrounding environment. As mosses grow and establish themselves on rocks, their rhizoids secrete acids that slowly break down the rocks, contributing to the formation of soil. This process is important for the colonization of other plants in the area, as the soil created by mosses provides a suitable substrate for other plant species to grow.
10.
Ferns grow from an underground
Correct Answer
D. Stem
Explanation
Ferns grow from an underground stem, known as a rhizome. The rhizome is responsible for producing both the roots and the fronds (leaves) of the fern. It serves as a storage organ for nutrients and water, allowing the fern to survive in various environments. The spores, on the other hand, are reproductive structures produced by the fern and are not involved in its growth or development.
11.
Mosses and liverworts absorb water from the soil through the process of
Correct Answer
D. Osmosis
Explanation
Mosses and liverworts are non-vascular plants that lack specialized tissues for water transportation. Instead, they rely on osmosis to absorb water from the soil. Osmosis is the movement of water molecules from an area of higher water concentration (in this case, the soil) to an area of lower water concentration (inside the plant cells). This process allows these plants to take up water and nutrients necessary for their growth and survival.
12.
Seed plants are divided into two groups called
Correct Answer
A. Conifers and flowering plants
Explanation
Seed plants are divided into two groups called conifers and flowering plants. Conifers are a group of plants that produce seeds in cones and have needle-like leaves. They are typically evergreen and include trees such as pines, spruces, and firs. Flowering plants, on the other hand, produce seeds enclosed in a fruit and have a wide range of leaf shapes. They are the most diverse group of plants and include trees, shrubs, and herbaceous plants. This division is based on the different reproductive structures and characteristics of these two groups of seed plants.
13.
Cedar and pine trees are classified as
Correct Answer
C. Conifers
Explanation
Cedar and pine trees are classified as conifers because they belong to the group of plants known as coniferophyta. Conifers are characterized by their needle-like or scale-like leaves, their production of cones as reproductive structures, and their ability to adapt to various environmental conditions. Cedar and pine trees are both examples of conifers, as they possess these defining characteristics.
14.
A small, new plant along with nutrients is found inside a
Correct Answer
B. Seed
Explanation
A seed is the correct answer because it is a small, new plant that contains all the necessary nutrients for growth. Seeds are the reproductive structures of plants and are typically enclosed in a protective outer covering. Inside the seed, there is an embryo plant along with stored food reserves that provide the necessary nutrients for the plant to germinate and grow. This allows the plant to establish itself and eventually develop into a mature plant.
15.
The spore cases (sori) of most ferns can be found
Correct Answer
C. On the underside of leaves
Explanation
Ferns have spore cases, known as sori, which are typically found on the underside of their leaves. This location is advantageous as it provides protection and prevents the spores from being easily washed away by rain or wind. Additionally, being on the underside of the leaves allows for efficient dispersal of the spores when they are released. This strategy increases the chances of successful reproduction for ferns.
16.
Which group of plants usually has needle-shaped leaves?
Correct Answer
B. Conifers
Explanation
Conifers usually have needle-shaped leaves. Conifers are a group of plants that include trees and shrubs such as pine, spruce, and fir. The needle-shaped leaves of conifers help reduce water loss through transpiration, as they have a smaller surface area compared to broad leaves. This adaptation allows conifers to thrive in dry and cold environments. Unlike flowering plants, mosses, and ferns, conifers have adapted to survive in harsh conditions and have needle-shaped leaves as a characteristic feature.
17.
Flowering plants are important to us because
Correct Answer
D. All of the above
Explanation
Flowering plants are important to us because they provide us with food, such as fruits, vegetables, and grains. They also provide us with oxygen through the process of photosynthesis, which is crucial for our survival. Additionally, flowering plants are used for decorations, such as in gardens, floral arrangements, and landscaping. Therefore, all of the given options are correct as they highlight different ways in which flowering plants are beneficial to us.
18.
Potatoes, strawberries, and oranges are all examples of
Correct Answer
D. Flowering plants
Explanation
Potatoes, strawberries, and oranges are all examples of flowering plants because they produce flowers as part of their reproductive process. Conifers, ferns, and mosses do not produce flowers.
19.
Which of the following is a vascular plant that reproduces via spores?
Correct Answer
C. Ferns
Explanation
Ferns are a type of vascular plant that reproduces via spores. Unlike flowering plants that reproduce through seeds, ferns produce spores that are released into the environment. These spores can develop into new fern plants under suitable conditions. Mosses and conifers, on the other hand, reproduce through different methods. Mosses reproduce through spores as well, but they are non-vascular plants. Conifers, such as pine trees, reproduce through seeds. Therefore, ferns are the correct answer as they are vascular plants that reproduce via spores.
20.
Flowering plants can be fertilized by
Correct Answer
D. All of the above
Explanation
Flowering plants can be fertilized by wind, insects, and birds. Wind-pollinated plants produce lightweight pollen that is easily carried by the wind to reach other plants for fertilization. Insect-pollinated plants attract insects with colorful flowers and sweet nectar, and these insects transfer pollen between flowers as they move. Similarly, bird-pollinated plants have bright, showy flowers and produce nectar to attract birds, which inadvertently carry pollen from one flower to another. Therefore, all of these methods are possible ways for flowering plants to be fertilized.
