1. Which of the following is an example of an annual plant?
A. Sunflower
B. Oak tree
C. Apple tree
D. Pear tree
Answer: a) Sunflower
Rationale: Annual plants complete their life cycle in one year, such as
sunflowers, which grow, flower, produce seeds, and die within a single
growing season.
2. What is the process of pollination?
A. Fertilization of ovules by sperm cells
B. Transfer of pollen from male to female flower parts
C. Growth of a seed into a new plant
D. Movement of plant roots through soil
Answer: b) Transfer of pollen from male to female flower parts
Rationale: Pollination is the process by which pollen is transferred from
the male part (anther) to the female part (stigma) of a flower, enabling
fertilization.
,3. Which of the following is an example of a secondary nutrient for
plants?
A. Nitrogen
B. Phosphorus
C. Calcium
D. Iron
Answer: c) Calcium
Rationale: Secondary nutrients, like calcium, magnesium, and sulfur,
are important for plant growth but are required in smaller quantities
than primary nutrients (N, P, K).
4. Which of the following is the primary function of soil in agriculture?
A. Provide nutrients
B. Support plant roots
C. Control water flow
D. Store carbon
Answer: b) Support plant roots
Rationale: The soil provides mechanical support for plant roots,
anchoring them in place and allowing them to access necessary
nutrients and water.
5. Which of the following nutrients is most commonly deficient in
soils?
, A. Nitrogen
B. Calcium
C. Sulfur
D. Potassium
Answer: a) Nitrogen
Rationale: Nitrogen is one of the most essential nutrients for plant
growth, and it is often deficient in soils because it is easily leached away
by rainwater.
6. What is the primary goal of integrated pest management (IPM)?
A. Complete eradication of pests
B. Use of only organic pesticides
C. Minimizing the use of chemicals while controlling pests
D. Maximizing the use of synthetic pesticides
Answer: c) Minimizing the use of chemicals while controlling pests
Rationale: IPM focuses on using a combination of biological, cultural,
mechanical, and chemical tools to manage pests with minimal
environmental impact.
7. Which of the following is an example of an animal-based fertilizer?
A. Compost
B. Bone meal
C. Green manure
A. Sunflower
B. Oak tree
C. Apple tree
D. Pear tree
Answer: a) Sunflower
Rationale: Annual plants complete their life cycle in one year, such as
sunflowers, which grow, flower, produce seeds, and die within a single
growing season.
