What to expect: This mock test covers key concepts from the Transpiration chapter — including application-based and competency-focused questions aligned with how ICSE actually sets the paper.
Tip: Attempt without notes first to identify gaps, then review explanations for any wrong answers. Retake after a few days for best retention.
Sample questions
-
1.Transpiration is best defined as (tick-mark the correct option)
- a.loss of water from the plant.
- b.loss of water as vapour from the plants.
- c.evaporation of water from the surface of leaves.
-
2.Assertion: Leaves are reduced to spines in cactus. Reason: Leaves are modified to form spines to reduce the leaf lamina. (a) If both assertion and reason are true and reason is the correct explanation of assertion. (b) If both assertion and reason are true, but reason is not the correct explanation of assertion. (c) If assertion is true but reason is false. (d) If both assertion and reason are false.
- A.If both assertion and reason are true and reason is the correct explanation of assertion.
- B.If both assertion and reason are true, but reason is not the correct explanation of assertion.
- C.If assertion is true but reason is false.
- D.If both assertion and reason are false.
-
3.Loss of water as droplets from hydathodes is called
- A.Transpiration
- B.Bleeding
- C.Guttation
- D.Evaporation
-
4.There is a general belief that forests tend to bring more frequent rains. Which of the following provides the most accurate scientific explanation for this phenomenon?
- A.Forests release large amounts of water vapor through transpiration, increasing humidity and leading to cloud formation and precipitation.
- B.Forests absorb all sunlight, reducing evaporation from the ground and directly causing rainfall.
- C.Forests produce oxygen that chemically reacts with atmospheric gases to form rain clouds.
- D.Forests block wind movement, forcing moisture-laden air to rise and cool, but this has no direct link to rainfall frequency.
-
5.Why are leaves modified into spines in some xerophytes?
- A.To reduce water loss by minimizing surface area exposed to the atmosphere.
- B.To increase photosynthesis efficiency in dry conditions.
- C.To attract pollinators in arid environments.
- D.To store excess water in the plant tissues.
