Question

Which tissue contains chloroplast in cells?

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

Answer 1

The correct option is D

Chlorenchyma

The correct option is D.

Explanation of the correct option:

1. Chloroplasts are found in the cells of all green and algal tissues.
2. Chloroplasts can also be found in non-green photosynthetic tissues, such as the brown blades of gigantic kelp or the red leaves of certain plants.
3. Chloroplasts are organelles found in plant cells that use the process of photosynthetic energy conversion to transform light energy into relatively stable chemical energy.

Explanation of incorrect options:

Option A:

1. The sclerenchyma is one of three types of ground, or fundamental, tissue in plants.
2. Sclerenchyma doesn't have chloroplast.
3. Sclerenchyma serves to provide structural support to plants.

Option B:

1. Aquatic plants have modified parenchymatous tissues called aerenchyma.
2. The air is surrounded by this tissue, which also gives the plant portions their buoyancy, in order for these components to float in water.
3. Examples are Hydrilla, Ceratophyllum, Lotus, Eichhornia, and Vallisneria.
4. Aerenchyma also doesn't have chloroplast.

Option C:

1. Parenchyma, in plants, tissue is usually composed of living cells that are thin-walled, and not specialized in structure.
2. Parenchyma doesn't have chloroplast either.
3. They perform functions such as photosynthesis, food storage, juice secretion and gas exchange.

Final answer: Chloroplasts are found in Chlorenchyma.
