Chlorenchyma cells are chlorophyll containing

A. Sclerenchyma

B. Epidermis

C. Parenchyma

D. Phloem

Option A: Sclerenchyma

Sclerenchyma is composed of sclerenchymatous cells with walls thickened by lignin, a substance that provides rigidity to plants. Mature sclerenchyma cells are typically dead and have lignin-rich secondary walls.

Option A is not correct.

Option B: Epidermis

The epidermis is a single layer of cells covering leaves, flowers, roots, and stems. It acts as a protective barrier between the plant and the external environment. Its functions include preventing water loss, regulating gas exchange, secreting metabolic compounds, and absorbing water and minerals (in roots).

Option B is not correct.

Option C: Parenchyma
Chlorenchyma, a type of parenchyma, consists of cells rich in chloroplasts that carry out photosynthesis. These are commonly found in leaves and young shoots. Chlorenchyma occurs in two forms:

1. Palisade cells – elongated and compactly arranged.
2. Spongy cells – loosely arranged, irregular in shape, with intercellular spaces.

Option C is correct.

Option D: Phloem

Phloem is vascular tissue that transports organic nutrients throughout the plant. It also conducts signaling molecules and provides structural support. Phloem consists mainly of sieve elements, parenchyma, and sclerenchyma cells.

Option D is not correct.

Therefore, the correct answer is Option C: Parenchyma.
