Question

If the parenchyma cells contain chloroplasts then the tissue comes to be called:

• A. Collenchyma
• B. Aerenchyma
• C. Chlorenchyma
• D. Sclerenchyma

Answer 1

The correct option is C

Chlorenchyma

The correct option is C.

Explanation of the correct option:

1. Chlorenchyma is a form of parenchyma tissue that contains chloroplasts.
2. Chlorenchyma is present in the stems of some plant species as well as the mesophyll tissue of plant leaves.
3. Palisade mesophylls, which contain large concentrations of chloroplasts, are in charge of the actual photosynthetic process.
4. This tissue is often made up of live cells that are thin-walled, unspecialized in structure, and hence amenable to numerous tasks through differentiation.

Explanation of the incorrect option:

Option A:

Collenchyma is a form of parenchyma that gives fragile stems, petioles, pedicles, and young leaves flexibility.

Option B:

1. Aerenchyma is parenchyma that has air gaps.
2. It is present in many aquatic plants and provides buoyancy.
3. It is responsible for aquatic plants' capacity to float.

Option C:

1. Sclerenchyma is a form of parenchyma that hardens and rigidifies the plant.
2. It is the plant's supporting tissue.
3. Sclerenchyma is classified into two types: cellular fibres and sclereids.
4. Cellulose, hemicellulose, and lignin are components of their cell walls.

Final answer: If the parenchyma cells contain chloroplasts then the tissue comes to be called as Chlorenchyma.
