How vital are tissues to an organism? Why is it so?
It is quite impressive that in our body, from bones to organs like the intestine, lungs, heart and even blood is made up of connective tissues.
A tissue is stated as a cluster of cells with a common origin, uniform in structure and work together to execute a specific function.
Types of tissues
a) Are plants and animals made of the same type of tissues?
b) What do you think about the structure and functions of plant and animal cells?
c) Do they have identical structure?
d) Do they perform the same functions?
c) Do they have identical structure?
d) Do they perform the same functions?
The below table showing the differences between plant and animal tissues will explain the answers for these questions.
The tissues are broadly categorised into plant tissues and animal tissues. There are several observable difference between the two.
Difference between plant and animal tissues
S.No | Plant tissue | Animal tissue |
1 | Dead supportive tissues are abundant. | Living supportive tissues are abundant. |
2 | Require less energy. | Requires more energy. |
3 | Differentiation of meristematic into permanent tissues. | Absent in animals. |
4 | Structural organization is simple. | The structural organization is complex. |
5 | Meant for stationary. | Shows high mobility. |
6 | Shows continuous division in meristematic tissue. | Growth is restricted. |
7 | Dead cells are for mechanical support. | Support for locomotion. |
8 | Two types: Meristematic and permanent tissues. | Four types: Epithelial, connective, muscular, and nervous tissue. |
9 | There is a differentiation of tissues based on their dividing capacity. | Differentiation is absent due to growth is uniform. |
