Which of the following is a non-vascular plant?

  1. Fern

  2. Moss

  3. Pine

  4. Oak


Correct Option: B
Explanation:

Mosses are non-vascular plants, meaning they lack specialized tissues for transporting water and nutrients.

What is the process by which plants convert light energy into chemical energy?

  1. Photosynthesis

  2. Cellular respiration

  3. Transpiration

  4. Nitrogen fixation


Correct Option: A
Explanation:

Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to produce glucose and oxygen.

Which plant structure is responsible for absorbing water and nutrients from the soil?

  1. Roots

  2. Stems

  3. Leaves

  4. Flowers


Correct Option: A
Explanation:

Roots are responsible for absorbing water and nutrients from the soil and anchoring the plant in place.

What is the term for the process by which plants lose water vapor through their leaves?

  1. Photosynthesis

  2. Transpiration

  3. Respiration

  4. Nitrogen fixation


Correct Option: B
Explanation:

Transpiration is the process by which plants lose water vapor through their leaves, helping to regulate their temperature and transport water and nutrients.

Which of the following is an example of a gymnosperm?

  1. Pine

  2. Fern

  3. Rose

  4. Sunflower


Correct Option: A
Explanation:

Pine is a gymnosperm, a group of seed plants that produce naked seeds, not enclosed in an ovary.

What is the largest group of flowering plants?

  1. Monocots

  2. Dicots

  3. Gymnosperms

  4. Pteridophytes


Correct Option: A
Explanation:

Monocots are the largest group of flowering plants, characterized by having one cotyledon (seed leaf) in their seeds.

Which of the following is an example of a legume?

  1. Pea

  2. Daisy

  3. Rose

  4. Sunflower


Correct Option: A
Explanation:

Pea is a legume, a type of flowering plant that produces pods containing seeds.

What is the process by which plants convert nitrogen gas into a usable form?

  1. Photosynthesis

  2. Nitrogen fixation

  3. Transpiration

  4. Respiration


Correct Option: B
Explanation:

Nitrogen fixation is the process by which plants convert nitrogen gas into a usable form, such as nitrates and nitrites.

Which of the following is an example of a carnivorous plant?

  1. Venus flytrap

  2. Rose

  3. Sunflower

  4. Daisy


Correct Option: A
Explanation:

Venus flytrap is a carnivorous plant that traps and digests insects to obtain nutrients.

What is the term for the process by which plants respond to light?

  1. Phototropism

  2. Geotropism

  3. Thigmotropism

  4. Hydrotropism


Correct Option: A
Explanation:

Phototropism is the process by which plants respond to light, typically by growing towards or away from it.

Which of the following is an example of a parasitic plant?

  1. Mistletoe

  2. Fern

  3. Rose

  4. Sunflower


Correct Option: A
Explanation:

Mistletoe is a parasitic plant that attaches itself to other plants and obtains nutrients from them.

What is the term for the mutualistic relationship between plants and pollinators?

  1. Pollination

  2. Symbiosis

  3. Mutualism

  4. Commensalism


Correct Option: C
Explanation:

Mutualism is the term for the mutually beneficial relationship between plants and pollinators, where pollinators help plants reproduce by transferring pollen, and plants provide pollinators with food and shelter.

Which of the following is an example of a plant adaptation to a dry environment?

  1. Succulent stems

  2. Deep roots

  3. Waxy leaves

  4. All of the above


Correct Option: D
Explanation:

Succulent stems, deep roots, and waxy leaves are all adaptations that help plants survive in dry environments.

What is the term for the process by which plants disperse their seeds?

  1. Seed dispersal

  2. Pollination

  3. Germination

  4. Reproduction


Correct Option: A
Explanation:

Seed dispersal is the process by which plants spread their seeds away from the parent plant, increasing the chances of survival and genetic diversity.

Which of the following is an example of a plant that reproduces asexually?

  1. Fern

  2. Rose

  3. Sunflower

  4. Daisy
