1.
In seed plants, the transfer of sperm from male reproductive
structures to female reproductive structures
Correct Answer
C. Pollination
Explanation
Pollination is the correct answer because it refers to the transfer of pollen from the male reproductive structures (stamen) to the female reproductive structures (pistil) in seed plants. This transfer of pollen is essential for fertilization to occur, leading to the formation of seeds. Transpiration is the process of water movement through a plant, not directly related to the transfer of sperm. Cohesion refers to the attraction between water molecules.
2.
The type of vascular tissue that carries water upward from roots.
Correct Answer
D. Xylem
Explanation
Xylem is the correct answer because it is the type of vascular tissue that carries water upward from the roots. Xylem consists of specialized cells called tracheids and vessel elements that form a network of tubes, allowing water and dissolved minerals to be transported from the roots to the rest of the plant. This process is known as transpiration, where water is pulled up through the xylem by the cohesion and adhesion of water molecules. The other options, phloem, cotyledon, and bryophyte, are not involved in the upward transport of water in plants.
3.
What type of seed plant bears its seed directly on the
the surface of cones?
Correct Answer
B. Gymnosperm
Explanation
Gymnosperms are a type of seed plant that bear their seeds directly on the surface of cones. Unlike angiosperms, which have enclosed seeds, gymnosperms have naked seeds that are exposed on the scales of cones. This characteristic is unique to gymnosperms and distinguishes them from other types of seed plants such as angiosperms and bryophytes.
4.
Bryophytes include:
Correct Answer
D. Mosses
Explanation
Bryophytes are a group of non-vascular plants that include mosses, liverworts, and hornworts. This group does not include ferns, trees, or horsetails, as these plants belong to different plant groups. Mosses, on the other hand, are a type of bryophyte characterized by their small size, lack of true roots, and ability to absorb water and nutrients directly from their environment. Therefore, the correct answer is mosses.
5.
The plant shown above is classified as a(an)
Correct Answer
C. Angiosperm
Explanation
The plant shown above is classified as an angiosperm because it has flowers and produces seeds enclosed within a fruit. Angiosperms are a group of plants that have evolved to have specialized reproductive structures, such as flowers, which attract pollinators to aid in fertilization. They also produce seeds that are enclosed within a protective fruit, which aids in dispersal. This classification is supported by the image provided, which shows a plant with flowers and fruits.
6.
The embryo of a plant that is encased in a protective
covering and surrounded by a food supply is called a:
Correct Answer
C. Seed
Explanation
A seed is the correct answer because it is the embryo of a plant that is protected by a seed coat and contains a food supply to support its growth and development. Seeds are formed after fertilization and are responsible for the reproduction and dispersal of plants. They can be found in various shapes, sizes, and structures, and are crucial for the survival and propagation of plant species.
7.
The supporting structure that connects the roots and leaves of a plant.
Correct Answer
D. Stem
Explanation
The stem is the supporting structure that connects the roots and leaves of a plant. It provides stability and allows the transport of water, nutrients, and sugars between the roots and leaves. The stem also plays a crucial role in supporting the plant's weight and positioning the leaves for optimal sunlight exposure.
8.
An angiosperm that has one seed leaf in its embryo is
called a:
Correct Answer
A. Monocot
Explanation
An angiosperm that has one seed leaf in its embryo is called a monocot. Monocots are a type of flowering plant that typically have parallel veins in their leaves, flower parts in multiples of three, and scattered vascular bundles in their stems. They are characterized by having a single cotyledon or seed leaf in their embryo, which is the structure that provides nutrients to the developing plant. Examples of monocots include grasses, lilies, and orchids.
9.
What surrounds and protects a plant embryo?
Correct Answer
B. A seed coat
Explanation
A seed coat surrounds and protects a plant embryo. It is a tough outer covering that shields the embryo from mechanical damage, pathogens, and unfavorable environmental conditions. The seed coat also helps in maintaining the embryo's moisture levels and prevents it from drying out. Additionally, the seed coat plays a crucial role in seed dormancy, controlling the timing of germination and ensuring the embryo's survival until favorable conditions for growth are present.
10.
Which type of angiosperm lives for more than two years?
Correct Answer
B. Perennial
Explanation
Perennial is the correct answer because it refers to a type of angiosperm that lives for more than two years. Unlike annuals and biennials, which complete their life cycle in one or two years respectively, perennials can live for multiple years, often regrowing and flowering each year. Terrestrial, on the other hand, refers to plants that grow on land rather than in water, but it does not specifically indicate the lifespan of the plant.
11.
What is the early developmental stage of the sporophyte plant called?
Correct Answer
D. An embryo
Explanation
The early developmental stage of the sporophyte plant is called an embryo. During this stage, the plant is in its earliest form and is not yet fully developed. The embryo is formed through the process of fertilization, where the male and female gametes combine to form a zygote. The zygote then undergoes cell division and differentiation to develop into an embryo, which eventually grows into a mature sporophyte plant.
12.
Any flowering plant:
Correct Answer
A. Angiosperm
Explanation
Angiosperms are a type of flowering plant that produce seeds enclosed in a protective structure called a fruit. They are characterized by having flowers, which are reproductive structures that attract pollinators. Angiosperms are the most diverse group of plants on Earth and include familiar plants such as roses, sunflowers, and oak trees. They have evolved various adaptations that allow them to thrive in different environments, making them successful colonizers of terrestrial habitats.
13.
What is the seed-bearing structure of an angiosperm called?
Correct Answer
B. Flower
Explanation
The seed-bearing structure of an angiosperm is called a flower. Flowers contain the reproductive organs of the plant, including the male parts (stamen) which produce pollen, and the female parts (pistil) which contain the ovary where the seeds are formed. This is in contrast to gymnosperms, which have cones as their seed-bearing structures.
14.
Nonvascular plant
Correct Answer
C. Bryophytes
Explanation
Bryophytes are nonvascular plants that lack specialized tissues for conducting water and nutrients. They include mosses, liverworts, and hornworts. Unlike tracheophytes (vascular plants), bryophytes do not have true roots, stems, or leaves. They rely on direct absorption of water and nutrients from their surroundings. Monocots and dicots, on the other hand, are two categories of flowering plants (angiosperms) that are part of tracheophytes. Monocots have one cotyledon (seed leaf) and dicots have two. Therefore, the correct answer is bryophytes.
