Transpiration MCQs Class 10 Concise ICSE Biology Selina Solutions Ch-5
Que-1:The process of evaporative loss of water from the aerial parts of plant is:
- Ascent of sap
- Translocation
- Transpiration
- Exudation
Sol: Transpiration
Hint: As definition Loss of water in form of vapors from aerial parts of plant is Transpiration
Que-2: The process of oozing out of the fluids from a plant part is :
- Transpiration
- Excretion
- Transportation
- Exudation
Sol: Exudation
Hint: Exudation refers to oozing out of fluids from plant either from hydathodes or from injured part.
Que-3: Transpiration occurs:
- More from adaxial surface of a monocot leaf
- More from adaxial surface of a dicot leaf
- Equal from both the surfaces of a dicot leaf
- More from abaxial surface of a dicot leaf
Sol: More from abaxial surface of a dicot leaf
Hint: The lower or the abaxial side of leaf has more stomata which results in more transpiration.
Que-4: Guttation takes place through:
- Stomata
- Lenticels
- Hydathodes
- Cuticle
Sol: Hydathodes
Hint: Hydathodes are minute pores found in leaves through which fluid oozes out in form of tiny droplets.
Que-5: The apparatus used to measure the rate of transpiration is
- Barometer
- Clinostat
- Manometer
- Potometer
Sol: Potometer
Hint: Gannong Potometer measure the rate of transpiration
Que-6: Which of the following is an external factor affecting the rate of transpiration ?
- Number of stomata
- Exposed surface
- Humidity
- Sunken stomata
Sol: Humidity
Hint: If the humidity is more then the diffusion of water vapour from sub stomatal space is slow
Que-7: The upper layer of mesophyll in a leaf consists of elongated ground tissue called:
- Spongy parenchyma.
- Palisade cells
- Xylem cells
- Phloem cells
Sol: Palisade cells
Hint: The upper layer of mesophyll in a leaf consists of elongated ground tissue called palisade mesophyll.
Que-8: Transpiration is significant for all except:
- Cooling effect
- Suction pull
- Ascent of sap
- Translocation of food
Sol: Translocation of food
Hint: Translocation is a process in which food is carried out by phloem tissue from leaves to other part of the plant.
Que-9: Hydathodes are located on:
- At the petiole
- Upper surface of leaves
- Lower surface of leaves
- Margins of leaves
Sol: Margins of leaves
Hint: Hydathodes are the tiny pores located on leaf margins. They are responsible for guttation.
Que-10: When guard cells are flaccid, the stoma must be:
- Open
- Neither open nor closed
- Closed
- None of these
Sol: Closed
Hint: When guard cells are flaccid, their inner wall is relaxed closing the stomata. Similarly, when the guard cells become turgid the inner wall is pulled outwards opening the stomata.
