Question

Chlorenchyma tissues are types of parenchymatous tissues having chlorophyll.
A. True
B. False

Answer 1

Hint: Parenchyma tissues form the most common type of tissues in plants. It is present in the cortex and medulla of stems and roots, as well as in leaves, fruits pulp, and seeds endosperm.

Complete answer:
A group of cells that are similar in structure and work together to achieve a particular function forms a tissue. The tissues of a plant are broadly categorized as meristematic and permanent. Meristematic tissues are present on the growing or dividing regions of a plant. Permanent tissues are those tissues that have lost the power of division.

The basic packing tissue is formed by several layers of cells. This tissue is a type of permanent tissue known as parenchyma. It is composed of relatively simple cells with thin cell walls. These cells are living cells. Typically they are loosely packed, with wide intercellular spaces. This tissue supports the plants and also stores food. In some cases, it may contain chlorophyll. Such a parenchyma is known as chlorenchyma.

A chlorenchyma has a plastid containing chlorophyll called chloroplast. A chloroplast is a plastid with high chlorophyll content. Chlorenchyma cells are mostly found in the mesophyll region of leaves. They may also occur in the green stems of some plants.

In aquatic plants, large air cavities are present in parenchyma to give buoyancy to the plants to help them float. Such a parenchyma type is called aerenchyma

Thus, the given statement is true.

Note: Chlorenchyma tissues are parenchyma tissues present on the leaf. They are living cells. Another type of permanent tissue that gives mechanical support to plants is the collenchyma. It is present on the leaf stalks below the epidermis.
