(i) It provides support and flexibility to the body parts. (ii) It smoothens surface at joints.
The functions of bone are: (i) It provides shape to the body. (ii) It provides skeletal support to the body. (iii) It anchors the muscles. ...
It helps in absorption, excretion, secretion, it also provides mechanical support.
True. Epithelial tissue is the simplest tissue.
Each stomata is bounded by a pair of specialised kidney-shaped epidermal cells called guard cells.
They are elongated cells with tapering ends.
There are three types: (a) RBC’s (b) WBC’s and (c) Platelets.
Intercalary tissue.
(F). Tissues present at the lateral surface of the stem are called lateral tissue.
Present at the tips of roots and stems.
The three types are: (a) Apical tissue- tips of root and shoot (b) Lateral tissue- sides of stem (c) Intercalary tissue- at nodes
The process of taking up a permanent shape, size and function by cells is called differentiation.
Meristematic tissue and permanent tissue.
Plant tissues and animal tissues.
It helps in growth, organisation of different organs and performing functions.
When the cells have air-filled large cavities of parenchyma, it is called aerenchyma. Aerenchyma helps aquatic plants in floating.
Phloem constitutes the sieve tubes, companion cell, phloem parenchyma and phloem fibres.
Sclerenchyma.
