Question

Parenchymatous cells performing photosynthesis are called-

Answer 1

Hint: The tissues are a group of similar cells specialized to perform a common function. The simple tissues are made up of only one type of cell and are present inside the plants. Simple tissues are mainly categorized as – collenchyma, sclerenchyma. Parenchyma is one such simple tissue.

Complete Answer:
The cells of parenchyma tissues are living and thin-walled. It is distributed in all the body parts of plants. The cells are loosely packed. These can help in healing the wounds and regeneration. The reproductive parts of plants are parenchymatous in nature. It provides support to the plant and also stores food in the form of starch. The parenchyma cells which have large air cavities are called aerenchyma and they provide buoyancy to plants and help them to float. They also perform many functions like – storage, photosynthesis, transport, protection, gas exchange, totipotent, buoyancy.
Parenchymatous cells are divided into many types – chlorenchyma, transfer cell, vascular parenchyma, storage parenchyma, prosenchyma, aerenchyma, epidermis, conjunctive.
In these types only the chlorenchyma cells perform photosynthesis because it contains chlorophyll, a green colour pigment which is very essential for making the food on its own in the presence of sunlight, water, carbon dioxide.

Note:
Parenchyma cells contain protoplasts and nuclei. It also contains chloroplast that helps in performing photosynthesis. It mainly occurs in the shape of polyhedral or isodiametric. The intercellular space is less and their particles are tightly packed. The cell wall of parenchyma cells is made up of hemicelluloses and cellulose. They have multiple small vacuoles that act as water reservoirs of plants.
