1. What is the term for the movement of water through plants from
roots to leaves?
A. Absorption
B. Transpiration
C. Photosynthesis
D. Evaporation
Answer: b) Transpiration
Rationale: Transpiration is the process by which water is absorbed by
plant roots, moved through the plant, and evaporates from the leaves
into the atmosphere.
2. Which of the following is a method of weed control in organic
farming?
A. Herbicide application
B. Crop rotation
C. Genetic modification
D. Use of synthetic fertilizers
Answer: b) Crop rotation
Rationale: Organic farming uses cultural practices like crop rotation to
control weeds by disrupting their growth cycle without the use of
synthetic chemicals.
,3. Which of the following is a key characteristic of agroecology?
A. Extensive use of chemical pesticides
B. Focus on monoculture farming
C. Emphasis on biodiversity and ecological balance
D. Heavy reliance on synthetic fertilizers
Answer: c) Emphasis on biodiversity and ecological balance
Rationale: Agroecology promotes sustainable farming practices that
consider ecological principles, such as biodiversity and ecosystem
balance.
4. What is the process of breaking down organic matter in soil called?
A. Decomposition
B. Germination
C. Fermentation
D. Photosynthesis
Answer: a) Decomposition
Rationale: Decomposition is the process by which microorganisms
break down organic material, returning nutrients to the soil.
5. 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).
6. What is the term for the movement of substances within plant cells?
A. Diffusion
B. Osmosis
C. Active transport
D. Translocation
Answer: d) Translocation
Rationale: Translocation refers to the movement of water, nutrients,
and sugars within plant cells and between plant parts, facilitated by the
phloem and xylem.
7. What does the term "tillage" refer to in agriculture?
A. Harvesting crops
B. Preparing soil for planting
C. Watering crops
D. Applying fertilizers
roots to leaves?
A. Absorption
B. Transpiration
C. Photosynthesis
D. Evaporation
Answer: b) Transpiration
Rationale: Transpiration is the process by which water is absorbed by
plant roots, moved through the plant, and evaporates from the leaves
into the atmosphere.
