a. Aerenchyma i. Conduct food bidirectionally
b. Phloem ii. Buoyancy
c. Collenchyma iii. Complex tissue
d. Xylem iv. Localised thickenings

Answer 1

a. Aerenchyma ii. Buoyancy
b. Phloem i. Conduct food bidirectionally
c. Collenchyma iv. Localised thickenings
d. Xylem iii. Complex tissue

• Parenchyma cells with air spaces in them are called aerenchyma.
• Aerenchyma provides buoyancy to the aquatic plants and helps them to float on the water surface.
• Phloem is a vascular conductive tissue that transports food bidirectionally from leaves to other parts of the plant.
• Collenchyma is a simple permanent tissue that provides flexibility to the plant part due to an uneven cell wall with irregular thickening at the corners.
• Xylem is a vascular conductive tissue that transports water and minerals unidirectionally from the root to other plant parts.
