Botany Questions and Answers
1. What is the process by which plants use sunlight to convert carbon dioxide and water into glucose and oxygen?
a) Photosynthesis
b) Respiration
c) Fermentation
d) Transpiration
Answer: a) Photosynthesis
Explanation: Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll present in their leaves.
2. What is the primary function of the roots in plants?
a) Photosynthesis
b) Reproduction
c) Transport of water and minerals
d) Protection
Answer: c) Transport of water and minerals
Explanation: The roots of a plant absorb water and minerals from the soil and transport them to the stem and leaves.
3. What is the role of stomata in the leaves of plants?
a) Photosynthesis
b) Transpiration
c) Respiration
d) Reproduction
Answer: b) Transpiration
Explanation: Stomata are tiny openings on the surface of leaves that allow for the exchange of gases, such as oxygen and carbon dioxide, as well as the release of water vapor through a process called transpiration.
4. Which of the following plant hormones stimulates cell elongation and growth in plants?
a) Gibberellins
b) Auxins
c) Cytokinins
d) Abscisic acid
Answer: b) Auxins
Explanation: Auxins are plant hormones that promote cell elongation and growth in plants. They are responsible for various plant growth processes, such as stem and root elongation, phototropism, and gravitropism.
5. Which of the following is a plant adaptation to arid environments that helps reduce water loss?
a) Thick cuticle
b) Thin cuticle
c) Large stomata
d) Small stomata
Answer: a) Thick cuticle
Explanation: A thick cuticle on the leaves of a plant helps reduce water loss by providing a protective barrier that slows down the rate of water evaporation from the leaf surface.
6. Which part of the plant is responsible for the production of seeds?
a) Stem
b) Leaves
c) Flowers
d) Roots
Answer: c) Flowers
Explanation: The flowers of a plant contain reproductive structures that produce seeds. After pollination and fertilization, the ovules in the flowers develop into seeds.
7. Which of the following plant pigments is responsible for the red color in leaves during the fall season?
a) Chlorophyll
b) Xanthophyll
c) Carotenoids
d) Anthocyanins
Answer: d) Anthocyanins
Explanation: Anthocyanins are plant pigments responsible for the red color in leaves during the fall season. They are produced as a result of the breakdown of chlorophyll, which is the primary pigment responsible for green color in plants.
8. What is the function of the xylem in plants?
a) Transport of food
b) Transport of water and minerals
c) Support
d) Reproduction
Answer: b) Transport of water and minerals
Explanation: The xylem is a tissue in plants that is responsible for the transport of water and minerals from the roots to the stem and leaves.
9. Which of the following plant hormones is responsible for promoting lateral bud growth?
a) Auxins
b) Gibberellins
c) Cytokinins
d) Abscisic acid
Answer: c) Cytokinins
Explanation: Cytokinins are plant hormones that promote cell division and lateral bud growth in plants.
10. Which of the following is the largest group of land plants?
a) Angiosperms
b) Gymnosperms
c) Bryophytes
d) Pteridophytes
Answer: a) Angiosperms
Explanation: Angiosperms, also known as flowering plants, comprise the largest and most diverse group of land plants.
11. What is the main function of phloem in plants?
a) Photosynthesis
b) Water transport
c) Mineral absorption
d) Nutrient transport
Answer: d) Nutrient transport
Explanation: Phloem is responsible for the transport of organic nutrients, such as sugars and amino acids, from the leaves to the rest of the plant.
12. Which of the following plant tissues is responsible for the growth of the plant?
a) Dermal tissue
b) Vascular tissue
c) Ground tissue
d) Meristematic tissue
Answer: d) Meristematic tissue
Explanation: Meristematic tissue is responsible for the growth and development of the plant. It is the only tissue in the plant that is capable of cell division.
13. Which of the following is a type of asexual reproduction in plants?
a) Vegetative propagation
b) Cross-pollination
c) Self-pollination
d) Fertilization
Answer: a) Vegetative propagation
Explanation: Vegetative propagation is a type of asexual reproduction in plants, where a new plant is produced from a vegetative part of the parent plant, such as a stem or a leaf.
14. Which of the following is the male reproductive structure of a flower?
a) Stamen
b) Pistil
c) Petal
d) Sepal
Answer: a) Stamen
Explanation: The stamen is the male reproductive structure of a flower, consisting of the anther and filament.
15. Which of the following is a type of root system found in monocots?
a) Taproot system
b) Adventitious root system
c) Fibrous root system
d) Prop root system
Answer: c) Fibrous root system
Explanation: Monocots have a fibrous root system, where the roots are thin, numerous and spread out. This helps in anchoring the plant firmly in the soil and absorbing water and nutrients efficiently.
16. Which of the following is not a type of tissue system found in plants?
a) Dermal tissue system
b) Vascular tissue system
c) Ground tissue system
d) Secretory tissue system
Answer: d) Secretory tissue system
