10 Facts About Biological tissue
2.
Cells of this type of Biological tissue are roughly spherical or polyhedral to rectangular in shape, with thin cell walls.
| FactSnippet No. 1,111,087 |
3.
Cells of meristematic Biological tissue are similar in structure and have a thin and elastic primary cell wall made of cellulose.
| FactSnippet No. 1,111,088 |
4.
Meristematic Biological tissue cells have a large nucleus with small or no vacuoles because they have no need to store anything, as opposed to their function of multiplying and increasing the girth and length of the plant, with no intercellular spaces.

5.
Simple permanent Biological tissue is a group of cells which are similar in origin, structure, and function.

6.
Xylem Biological tissue is organised in a tube-like fashion along the main axes of stems and roots.
| FactSnippet No. 1,111,091 |
7.
The cells comprising an epithelial layer are linked via semi-permeable, tight junctions; hence, this Biological tissue provides a barrier between the external environment and the organ it covers.
| FactSnippet No. 1,111,092 |
8.
Epithelial Biological tissue helps to protect organs from microorganisms, injury, and fluid loss.
| FactSnippet No. 1,111,093 |
9.
Muscle Biological tissue is separated into three distinct categories: visceral or smooth muscle, found in the inner linings of organs; skeletal muscle, typically attached to bones, which generate gross movement; and cardiac muscle, found in the heart, where it contracts to pump blood throughout an organism.

10.
Biological tissue was "the first to propose that tissue is a central element in human anatomy, and he considered organs as collections of often disparate tissues, rather than as entities in themselves".
