Explanation:

1. Plant tissue and animal tissue - definition
2. Cells of plant tissue have cell wall. Cells of animal tissue do not have cell wall. ... These tissues require less energy and maintenance as plants do not require movement. Due to entensive body mobility these tissues require more energy and maintenance.
3. Meristematic tissues are responsible for plant growth. They are present at the tips of roots,stem and branches. The cells present in these tissues constantly divide to produce new cells. The cells actively divide to produce new cells.
4. There are three types of meristematic tissues: apical (at the tips), intercalary or basal (in the middle), and lateral (at the sides).

Answer 2

Answer:

1) Plant tissue and animal tissue - definition

Cells of plant tissue have cell wall. Cells of animal tissue do not have cell wall. ... These tissues require less energy and maintenance as plants do not require movement. Due to entensive body mobility these tissues require more energy and maintenance.

2) Meristematic tissues are responsible for plant growth. They are present at the tips of roots,stem and branches. The cells present in these tissues constantly divide to produce new cells. The cells actively divide to produce new cells.

3) The meristem is divided into three types on the basis of the positions - apical meristem, intercalary meristem and lateral meristem.

(i) Apical meristem is found at the tips of roots, stem and branches. It is responsible for the increase in the length of the plant. It is divided into three zones-protoderm, procambium and ground meristem. Protoderm gives rise to epidermal tissue, procambium gives rise to primary vascular tissues and ground meristem gives rise to cortex and pith.

(ii) Intercalary meristem is present in the nodal region and is prominently found in monocotyledons, e.g grasses. As the name indicates, it is present in between the permanent tissues. It is derived from the apical meristem and is responsible for the elongation of internodes.

(iii) The meristem that is present along the longitudinal axis of stem and root is called lateral meristem. Vascular cambium and cork cambium are examples for lateral meristem. It produces secondary permanent tissues which result in the thickening of stem and root.
