1. What is the process of seed germination?
A. Seedling growth into mature plants
B. Conversion of light energy into chemical energy
C. The beginning of seed growth after it absorbs water
D. Pollination and fertilization of the flower
Answer: c) The beginning of seed growth after it absorbs water
Rationale: Germination is the process where a seed absorbs water,
swells, and begins to sprout, forming the first roots and shoots.
2. Which of the following crops is primarily grown for its seeds?
A. Cotton
B. Corn
C. Wheat
D. Soybean
Answer: b) Corn
Rationale: Corn is primarily grown for its seeds, which are used for
food, feed, and industrial products.
3. What is the term for the process by which plants take in carbon
dioxide from the atmosphere?
,A. Respiration
B. Photosynthesis
C. Transpiration
D. Germination
Answer: b) Photosynthesis
Rationale: Photosynthesis is the process by which plants absorb carbon
dioxide from the air and convert it into glucose using sunlight.
4. What is the term for the process of converting atmospheric nitrogen
into a usable form for plants?
A. Respiration
B. Photosynthesis
C. Nitrogen fixation
D. Transpiration
Answer: c) Nitrogen fixation
Rationale: Nitrogen fixation is the process by which nitrogen gas from
the atmosphere is converted into forms that plants can use, typically by
bacteria in the soil.
5. 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.
6. Which of these is a method for reducing water usage in agriculture?
A. Flood irrigation
B. Drip irrigation
C. Furrow irrigation
D. Spray irrigation
Answer: b) Drip irrigation
Rationale: Drip irrigation is more efficient in water usage, delivering
water directly to the root zone of plants with minimal evaporation.
7. Which of the following is an example of a cool-season crop?
A. Corn
B. Soybean
C. Lettuce
D. Cotton
Answer: c) Lettuce
Rationale: Cool-season crops, like lettuce, thrive in cooler temperatures
and are typically grown in spring or fall.
