Question

If the parenchyma cells contain chloroplasts then the tissue comes to be called as:
A. Collenchyma
B. Aerenchyma
C. Chlorenchyma
D. Sclerenchyma

Answer 1

Hint: Apart from chloroplast and chromoplasts, there are leucoplasts that help in the storage of starch, fats, and other carbohydrates. They are white to yellow in color.

Complete answer: Chlorenchyma is a type of parenchyma tissue that contains chloroplasts. It is photosynthetic
Chlorenchyma makes up the mesophyll tissue of plant leaves and is also found in the stems of certain plant species. Mesophyll cells are of palisade and spongy type.
Palisade mesophylls are responsible for the actual photosynthetic process as it contains high densities of chloroplasts. Spongy mesophyll cells are responsible for the conduction of gases
Parenchyma is a type of structural cell in plants.
This tissue is typically composed of living cells that are thin-walled, unspecialized in structure, and therefore adaptable with differentiation to various functions.

Additional information: Collenchyma is a type of parenchyma that confers elasticity to tender stems, petioles, pedicles, and young leaves.
Aerenchyma is a type of parenchyma containing air spaces. It is found especially in many aquatic plants and it confers buoyancy. It is responsible for the floating ability of aquatic plants.
Sclerenchyma is a type of parenchyma that makes the plant hard and rigid. It is the supporting tissue in plants. There are two types of sclerenchyma: fibers cellular and sclereids. Their cell walls contain cellulose, hemicellulose, and lignin.

Correct Answer: Option C: Chlorenchyma

Note: Chlorenchyma can be of different colors based on the type of chromoplast located in the cell. It can be green if it has chloroplasts and different colors (red, orange, yellow, and brown) if they have chromoplasts.
Chloroplasts in chlorenchyma can have chlorophyll a, chlorophyll b, fucoxanthin, xanthophyll, carotene, anthocyanin, etc. as photosynthetic pigments.
