Question

State the role of:

a. Aerenchyma

b. Chlorenchyma

c. Epidermal tissue​

Answer 1

$\huge\tt\red{ \star{\underline{Solution}{ \star}}}$

$\huge\tt\orange{Parenchyma}$

• Stores food and nutrients.
• Provides support and foundation.
• Involved in growth and development.
• Provide mechanical rigidity to the plants.
• They are the site of all metabolic activities.
• Helps in regeneration, healing and repair of wounds.
• Involved in the movement of water and other nutrients.
• In leaves, these cells are also responsible for photosynthesis and the exchange of gases.

$\huge\tt\pink{Chlorenchyma}$

• Chlorenchyma is a type of parenchyma cells which contains chloroplast.
• It consists of chloroplast,this helps in photoynthesis.
• It helps in manufacturing of starch which is stored for the future use of plant.

$\huge\tt\green{Epidermal \: tissue}$

• Provides protection against water loss.
• Regulates the process of gas exchange.
• Epidermis secretes metabolic compounds.
• Absorption of water and essential minerals.

Answer 2

Answer:

a. Aerenchyma

Step-by-step explanation:

Chlorenchyma: Parenchyma with chlorophyll which performs photosynthesis is called as chlorenchyma. Aerenchyma: In aquatic plants, cells of parenchyma have large air cavities to give buoyancy to the plant and is called aerenchyma .
