Which of the following is a non-vascular plant?

  1. Fern

  2. Moss

  3. Pine

  4. Sunflower


Correct Option: B
Explanation:

Mosses are non-vascular plants that lack specialized tissues for transporting water and nutrients. They absorb water and nutrients directly from the environment through their leaves and stems.

Which of the following is a gymnosperm?

  1. Oak

  2. Maple

  3. Pine

  4. Daisy


Correct Option: C
Explanation:

Gymnosperms are seed plants that do not produce flowers or fruits. Pines are gymnosperms that produce cones, which contain seeds.

Which of the following is an angiosperm?

  1. Fern

  2. Moss

  3. Pine

  4. Rose


Correct Option: D
Explanation:

Angiosperms are seed plants that produce flowers and fruits. Roses are angiosperms that produce flowers and rose hips, which contain seeds.

What is the function of stomata in plants?

  1. Transpiration

  2. Photosynthesis

  3. Reproduction

  4. Nutrient absorption


Correct Option: A
Explanation:

Stomata are small pores found on the leaves of plants. They allow for the exchange of gases, such as carbon dioxide and oxygen, and the release of water vapor through transpiration.

Which of the following is an adaptation that helps plants survive in dry environments?

  1. Thick, waxy leaves

  2. Deep roots

  3. Shallow roots

  4. Large leaves


Correct Option: A
Explanation:

Thick, waxy leaves help plants reduce water loss through transpiration, which is important for survival in dry environments.

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

  1. Venus flytrap

  2. Pitcher plant

  3. Sundew

  4. All of the above


Correct Option: D
Explanation:

Venus flytraps, pitcher plants, and sundews are all examples of carnivorous plants that trap and digest insects to obtain nutrients.

What is the role of mycorrhizae in plant growth?

  1. Nitrogen fixation

  2. Water absorption

  3. Nutrient absorption

  4. Reproduction


Correct Option: C
Explanation:

Mycorrhizae are symbiotic associations between fungi and plant roots. They help plants absorb nutrients from the soil, particularly phosphorus and nitrogen.

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

  1. Mistletoe

  2. Dodder

  3. Rafflesia

  4. All of the above


Correct Option: D
Explanation:

Mistletoe, dodder, and rafflesia are all examples of parasitic plants that obtain nutrients from other plants.

What is the function of flowers in plants?

  1. Reproduction

  2. Photosynthesis

  3. Nutrient absorption

  4. Water transport


Correct Option: A
Explanation:

Flowers are the reproductive structures of angiosperms. They produce pollen and ovules, which are necessary for fertilization and seed production.

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

  1. Fern

  2. Moss

  3. Strawberry

  4. Dandelion


Correct Option: C
Explanation:

Strawberries reproduce asexually through runners, which are stolons that grow horizontally above the ground and produce new plants.

What is the largest group of plants on Earth?

  1. Angiosperms

  2. Gymnosperms

  3. Bryophytes

  4. Pteridophytes


Correct Option: A
Explanation:

Angiosperms are the largest group of plants on Earth, with over 250,000 known species. They include flowering plants such as roses, sunflowers, and daisies.

Which of the following is an example of a plant that has adapted to living in aquatic environments?

  1. Water lily

  2. Lotus

  3. Duckweed

  4. All of the above


Correct Option: D
Explanation:

Water lilies, lotuses, and duckweed are all examples of plants that have adapted to living in aquatic environments, with features such as floating leaves and specialized root structures.

What is the role of lichens in the environment?

  1. Nitrogen fixation

  2. Decomposition

  3. Pollution absorption

  4. All of the above


Correct Option: D
Explanation:

Lichens play important roles in the environment, including nitrogen fixation, decomposition of organic matter, and absorption of pollutants from the air.

Which of the following is an example of a plant that has medicinal properties?

  1. Aloe vera

  2. Ginkgo biloba

  3. Echinacea

  4. All of the above


Correct Option: D
Explanation:

Aloe vera, ginkgo biloba, and echinacea are all examples of plants that have been used in traditional medicine for their medicinal properties.

What is the importance of plant diversity for the environment?

  1. Ecological balance

  2. Food and medicine

  3. Climate regulation

  4. All of the above


Correct Option: D
Explanation:

Plant diversity is important for maintaining ecological balance, providing food and medicine, regulating climate, and supporting a wide range of organisms.
