When you put a plant cell, fungal cell or bacterial cell in a very dilute external medium, the plant cell or fungal cell will absorb water but will not burst, whereas an animal cell will burst. Which part of the plant cell helps it withstand the pressure of incoming water?
The cell wall provides rigidity and resists the pressure generated when water enters a plant cell in a dilute medium.
143

RRB Group-D
22/09/2022 (Shift-I)
2022
✓ Answer:CRoot
The figure represents a root hair cell, which is found on the root and has an extension that increases the surface area for absorption of water and minerals.
146
Cork is impermeable to water and gases because of ____ found within its cells.
RRB Group-D
24-08-2022 (Shift-I)
2022
✓ Answer:DSuberin

Why are most plant cells dead at maturity?
RRB Group-D
22-08-2022 (Shift-I)
2022
✓ Answer:BBecause plants have a stationary or fixed lifestyle and need supportive tissues
The source explains that many mature plant cells are dead because plants are stationary and dead supportive tissues provide mechanical strength with lower maintenance needs.
149
In which different parts do plants store their waste products?
RRB Group-D
24-08-2022 (Shift-I)
2022
✓ Answer:DLeaves, vacuoles and old xylem
Plants can store waste products in leaves, vacuoles and old xylem, which can later be shed or isolated from active tissues.
150
Where can we find such cells with thickened cell walls in a plant?
RRB Group-D
19-09-2022 (Shift-I)
2022
✓ Answer:AIn phloem
The source identifies phloem as the location of the referenced cells with thickened cell walls and explains its role in transporting food.
