1. The suction force that pulls water absorbed by the roots to greater heights in tall trees is generated by:

A. respiration

B. transpiration ✔

C. transportation

D. photosynthesis

Option B: Transpiration is the process by which excessive water present in the plants is given out. This effect creates a pulling force that causes water and minerals to be absorbed to greater heights in the xylem.

2. In which order does water pàss through the cells of a plant, as the water travels from the roots to a leaf?

A. mesophyll cells → root hair → root cortex → xylem

B. root cortex → root hair → xylem → mesophyll cells ✔

C. root hair → mesophyll cells → root cortex → xylem

D. root hair → root cortex → xylem → mesophyll cells

Option B: The water molecules first pàss through the outer part of the roots (root cortex) and then through the root hair. From there, it gets pàssed on to the xylem and then at last, to the mesophyll cells.

3. A decrease in which factor normally causes transpiration rate to increase?

A. Humidity ✔

B. Intensity of light

C. Stomatal opening

D. Temperature

Option A: Humidity refers to the water vapour content in the atmosphere. Henceforth when the humidity content is low in the atmosphere, the transpiration rate is more. This means that the rate of transpiration inversely depends upon humidity.

4. In desert plants, the leaves are reduced to

A. thorns

B. tendrils

C. spines ✔

D. bristles

Option C: Through the reduction of leaves to spines, which is an adaptive measure taken by desert plants, the area for transpiration decreases. This helps them to retain water inside them.

5. Phloem consists of:

A. sieve tube cells, companion cells, phloem parenchyma and phloem fibres ✔

B. vessels, sieve tube cells, phloem parenchyma and phloem fibre

C. vessels, tracheids, phloem fibres and phloem parenchyma

D. vessels, tracheids, sieve tube cells, companion cells

Option A: Phloem is the living complex tissue in plants that helps to transport prepared food from the leaves to different plant parts. It is made up of sieve tubes, phloem parenchyma, companion cells and phloem fibres. All the constituent cells of phloem are living except for phloem fibres.

6. Xylem comprises of:

A. tracheids, fibres and parenchyma

B. tracheids, vessels and companion cells

C. tracheids, vessels, fibres and parenchyma ✔

D. tracheids, vessels, sieve cells and companion cells

Option C: Xylem is the non-living complex tissue in plants that conduct raw materials from the roots to the leaves for photosynthesis. It is made up of tracheids, xylem fibres, xylem parenchyma and vessels out of which vessels and tracheids form the tubular part.

7. Which of the following tissues are involved in water conduction?

A. xylem and phloem

B. tracheids and vessels ✔

C. xylem fibres and bast fibres

D. parenchyma and sclerenchyma

Option B: The main constituent cells of the xylem tissue - tracheids and vessels are responsible for water conduction in plants.

8. In both evaporation and transpiration, water is lost in the form of vapours, yet they differ from each other because:

A. frequency of water loss is different in both of them

B. both evaporation and transpiration are similar but the rate of water loss differs

C. transpiration is a physical process, while evaporation is physiological process

D. transpiration is a physiological process, while evaporation is a physical process. ✔

Option D: Transpiration is a process that is carried out only by living organisms (plants) and hence it is a physiological process. On the other hand evaporation is a process that takes place all the time - both in living organisms and in our environment. Hence, it is a physical process.
