Tissues Test - 10

•  Collenchyma tissue is found in leaf stalks below the epidermis.

•  The cells of this tissue are living, elongated and irregularly thickened at the corners.

•  There is very little intercellular space.

•  Sclerenchyma is present in stems, around vascular bundles, in the veins of leaves.

•  Collenchyma tissue is composed of elongated cells with irregularly thickened walls.

•  They provide structural support to the plant.

•  Collenchyma cells are living.

•  They have a thick cell wall made up of cellulose and pectin.

The Collenchyma has deposition of extra cellulose and pectin at the cell wall that provides structural support. Collenchyma is present in plant cell and its cell wall is thickened at the corners.

•  The flexibility in plants is due to the permanent tissue, collenchyma.

•  It allows easy bending in various parts of a plant (leaf, stem) without breaking.

•  It also provides mechanical support to plants.

A tissue is a group of cells that have a similar shape and function. Different types of tissues can be found in different organs.

An organ system is a group of biological structures that work together to perform a specific function or task. The human body is composed of 11 different organ systems.

A tissue is a group of cells that have a similar shape and function. Different types of tissues can be found in different organs. Blood and muscle are animal tissues while phloem is plant tissue.
