Plants with one cotyledon (like corn) are called

Monocots

Correct Answer

A. Monocots

Explanation

Plants with one cotyledon are called monocots. The term "monocot" refers to a group of flowering plants that have a single embryonic leaf, or cotyledon, in their seed. Examples of monocots include corn, wheat, rice, and lilies. This characteristic is one of the key features used to classify and differentiate plants into two major groups: monocots and dicots. Monocots also typically have parallel leaf veins, flower parts in multiples of three, and fibrous root systems.

If they have two cotyledons (like beans), they are called

Dicots

Correct Answer

A. Dicots

Explanation

Dicots are a type of flowering plants that have two cotyledons in their seeds. Cotyledons are the embryonic leaves present in the seed of a plant. Dicots are characterized by having flower parts in multiples of four or five, net-like veins on their leaves, and a taproot system. Examples of dicots include beans, roses, sunflowers, and oak trees.

What are the 7 things that plants need in order to grow properly?

Room to grow, the right temperature, light, water, air, nutrients, and time.

Correct Answer

A. Room to grow, the right temperature, light, water, air, nutrients, and time.

Explanation

Plants need several essential factors in order to grow properly. These include room to grow, as plants require space for their roots to spread and for their stems and leaves to expand. The right temperature is also crucial, as plants have specific temperature ranges in which they thrive. Light is necessary for photosynthesis, the process through which plants convert sunlight into energy. Water is vital for hydration and nutrient absorption. Air is needed for respiration and carbon dioxide intake. Nutrients, such as nitrogen, phosphorus, and potassium, are essential for plant growth. Lastly, time is required for plants to complete their life cycles and reach maturity.

5.

What do plants use that is in the air? What do they give in return?

Carbon dioxide and oxygen

Correct Answer

A. Carbon dioxide and oxygen

Explanation

Plants use carbon dioxide from the air during the process of photosynthesis to produce glucose, which is their source of energy. In return, they release oxygen into the atmosphere as a byproduct of photosynthesis. This exchange of gases is crucial for maintaining the balance of gases in the air and is essential for the survival of both plants and animals.

Fertilizers will help to keep the soil supplied with nutrients a plant needs. What are the 3 most important nutrients plants need?

Nitrogen, phosphorous, and potassium.

Correct Answer

A. Nitrogen, phosphorous, and potassium.

Explanation

Plants require various nutrients to grow and thrive, but the three most essential nutrients are nitrogen, phosphorous, and potassium. Nitrogen is crucial for promoting leaf and stem growth, as well as enhancing the plant's overall green color. Phosphorous aids in root development, flowering, and fruiting, contributing to the plant's overall strength and vitality. Potassium helps with water and nutrient uptake, disease resistance, and overall plant health. These three nutrients are commonly found in fertilizers and are vital for maintaining healthy soil and ensuring optimal plant growth.

7.

Which plant part carries water and food through the plant?

Root
Stem
Leaves
Flower
Seed

Correct Answer

A. Stem

Explanation

The stem carries water and food through the plant. It acts as a transportation system, allowing water and nutrients to move from the roots to the leaves, where photosynthesis occurs. The stem also transports sugars produced during photosynthesis from the leaves to other parts of the plant for growth and energy. Additionally, the stem provides support for the plant and helps it maintain an upright position.

Rate this question:

8.

Which part carries and protects the seed?

Root
Stem
Flower
Leaves
Fruit

Correct Answer

A. Fruit

Explanation

The fruit carries and protects the seed. In many plants, the fruit develops from the ovary of the flower after fertilization. The fruit acts as a protective covering for the seeds, preventing them from drying out or being damaged. It also helps in seed dispersal, as animals eat the fruit and then spread the seeds through their droppings.

Rate this question:

9.

Which part helps the plant produce seeds?

Roots
Leaves
Stem
Fruit
Flower

Correct Answer

A. Flower

Explanation

The flower helps the plant produce seeds through the process of pollination. Flowers contain reproductive organs, including the male stamen and the female pistil. When pollinators, such as bees or butterflies, visit the flower, they transfer pollen from the stamen to the pistil. This fertilizes the ovules within the pistil, leading to the development of seeds. Therefore, the flower plays a crucial role in the plant's reproductive cycle and the production of seeds.

10.

Which part is made of the blade and the petiole?

Root
Flower
Stem
Leaves
Seed

Correct Answer

A. Leaves

Explanation

The correct answer is leaves. Leaves are the part of a plant that is made up of the blade, which is the flat, green portion, and the petiole, which is the stalk that connects the blade to the stem. The blade is responsible for photosynthesis, while the petiole helps to support and position the blade for maximum sunlight exposure.

Rate this question:

11.

Which part takes up nutrients and water?

Roots
Stems
Seeds
Flowers
Leaves

Correct Answer

A. Roots

Explanation

Roots are the part of a plant that takes up nutrients and water from the soil. They have specialized structures called root hairs that increase the surface area for absorption. This allows the roots to absorb water and minerals that are essential for the plant's growth and survival. The stems, seeds, flowers, and leaves of a plant have different functions, but they do not play a direct role in nutrient and water uptake like the roots do.

An annual is :

A plant that grows, makes flowers, fruit and seed and then dies all in one growing season.
A plant that comes back year after year without replanting, usually from underground parts.
A plant that produces green leaves in one year, flowers the next year, and dies.

Correct Answer

A. A plant that grows, makes flowers, fruit and seed and then dies all in one growing season.

Explanation

The correct answer is "A plant that grows, makes flowers, fruit and seed and then dies all in one growing season." This definition accurately describes an annual plant, which completes its life cycle within a single growing season. Annuals typically germinate, grow, flower, produce seeds, and then die within a year. Unlike perennial plants that come back year after year, annuals need to be replanted each season.

A biennial is :

A plant that grows, makes flowers, fruit and seed, and dies all in one growing season.
A plant that comes back year after year without replanting, usually from underground parts.
A plant that produces green leaves in one year, flowers the next year, and then dies.

Correct Answer

A. A plant that produces green leaves in one year, flowers the next year, and then dies.

Explanation

A biennial is a plant that completes its life cycle in two years. In the first year, it produces green leaves and establishes its root system. In the second year, it flowers, produces seeds, and then dies. This is different from an annual plant that completes its life cycle in one growing season, and a perennial plant that comes back year after year without replanting.

A perennial is :

A plant that grows, makes flowers, fruit and seed, and dies all in one growing season.
A plant that comes back year after year without replanting, usually from underground parts.
A plant that produces green leaves in one year, flowers the next year, and dies.

Correct Answer

A. A plant that comes back year after year without replanting, usually from underground parts.

Explanation

The correct answer is "A plant that comes back year after year without replanting, usually from underground parts." This is because a perennial is a type of plant that has the ability to survive and regrow for multiple years, without the need for replanting. Perennials often have underground parts such as bulbs, rhizomes, or tubers that store nutrients and allow the plant to regrow each year. Unlike annuals, which complete their life cycle in one growing season, perennials can continue to grow, produce flowers and seeds, and survive for several years.
