In biology, a tissue is a collection of cells that have a common arrangement and serve the same role. The term tissue derives from the French word tissu, which implies “to weave.”
Animal tissues are made up of animal cells that have been clustered together. The composition, role, and origin of these tissues are all distinct. Epithelial, connective, elastic, and nervous tissues are the four types of tissues found in animals.
A tissue is a set of cells of similar configurations that collaborate to perform a particular purpose. Permanent and meristematic tissues are two types of plant tissues.
Permanent and meristematic tissues are two types of plant tissues.
There are live cells that have been spread out and have minute intercellular differences. Pectin and cellulose make up their cell walls. Collenchyma is located in the margins of leaves and branches, and it provides plants with structural flexibility and mechanical support.
There are elongated, dying cells with layers of lignin in their cell walls. There are no holes between the cells. Sclerenchyma can be present on the outside of seeds and nuts, as well as along vascular tissues in stems and leaf veins. Sclerenchyma gives the plant its power.
It aids in the transfer of water and dissolved compounds in the farm. Vessels, tracheids, xylem fibres, and xylem parenchyma are some of the xylem’s several elements. Lignin is found in Xylem fibres and Tracheids, and it gives structural support to the plant.
This tissue assists in the flow of food across the plant. Phloem fibres, sieve channels, phloem parenchyma, and partner cells are some of the several components of phloem.
Muscle tissue has the following purposes:
In this chapter, we learned about the tissues, their types and the characteristics. We also learned about the types of plant and animal tissues.
