1. The transport of water in plants takes place through:
Answer: B. Xylem
Explanation: Xylem is the vascular tissue responsible for transporting water and dissolved minerals from roots to all parts of the plant. It forms continuous tubes that help upward movement against gravity.
Explanation: Xylem is the vascular tissue responsible for transporting water and dissolved minerals from roots to all parts of the plant. It forms continuous tubes that help upward movement against gravity.
2. Food prepared in leaves is transported through:
Answer: B. Phloem
Explanation: Phloem carries food (sugars) made during photosynthesis from leaves to other plant parts. This process is called translocation.
Explanation: Phloem carries food (sugars) made during photosynthesis from leaves to other plant parts. This process is called translocation.
3. The upward movement of water is called:
Answer: B. Ascent of sap
Explanation: The upward flow of water and minerals from roots to leaves through xylem is known as ascent of sap.
Explanation: The upward flow of water and minerals from roots to leaves through xylem is known as ascent of sap.
4. Loss of water vapour from leaves is known as:
Answer: B. Transpiration
Explanation: Transpiration is the evaporation of water vapour through stomata. It creates suction force that helps pull water upward.
Explanation: Transpiration is the evaporation of water vapour through stomata. It creates suction force that helps pull water upward.
5. Stomata are mainly found on:
Answer: B. Leaves
Explanation: Stomata are tiny pores present on leaf surfaces that regulate gas exchange and transpiration.
Explanation: Stomata are tiny pores present on leaf surfaces that regulate gas exchange and transpiration.
6. Water absorption occurs mainly through:
Answer: A. Root hairs
Root hairs increase surface area and absorb water efficiently from soil.
Root hairs increase surface area and absorb water efficiently from soil.
7. Minerals are transported along with water in:
Answer: B. Xylem
Mineral salts dissolve in water and move through xylem vessels.
Mineral salts dissolve in water and move through xylem vessels.
8. Food transport in plants is bidirectional in:
Answer: B. Phloem
Phloem can move food both upward and downward as needed.
Phloem can move food both upward and downward as needed.
9. Transpiration helps in:
Answer: D. All of these
It cools plant, pulls water upward, and aids mineral transport.
It cools plant, pulls water upward, and aids mineral transport.
10. Opening and closing of stomata is controlled by:
Answer: A. Guard cells
Guard cells regulate stomatal aperture by changing shape.
Guard cells regulate stomatal aperture by changing shape.
11. Example of vascular plant tissue:
Answer: C. Both
Both are conducting tissues forming vascular bundles.
Both are conducting tissues forming vascular bundles.
12. Water moves upward due to:
Answer: B. Transpiration pull
Evaporation creates suction force drawing water upward.
Evaporation creates suction force drawing water upward.
13. Sugars are produced in:
Answer: B. Leaves
Photosynthesis in leaves produces glucose.
Photosynthesis in leaves produces glucose.
14. Transport tissue in bark is:
Answer: B. Phloem
Phloem lies toward outer side forming bark.
Phloem lies toward outer side forming bark.
15. Loss of water mainly occurs through:
Answer: B. Stomata
They are primary sites of transpiration.
They are primary sites of transpiration.
16. Transport of food is called:
Answer: A. Translocation
Movement of prepared food via phloem.
Movement of prepared food via phloem.
17. Water enters roots by:
Answer: B. Osmosis
Water moves from higher to lower concentration across membranes.
Water moves from higher to lower concentration across membranes.
18. Plants need transport system because:
Answer: D. All
Large size demands specialized transport tissues.
Large size demands specialized transport tissues.
19. Continuous tubes for water transport are:
Answer: A. Vessels
Xylem vessels form pipe‑like structures.
Xylem vessels form pipe‑like structures.
20. Transport in plants occurs through:
Answer: A. Vascular tissues
Xylem and phloem together form transport system.
Xylem and phloem together form transport system.
