Cell Wall

Cell Wall

Cell wall is non.living and outer rigid covering of cells. It give protection to the cell against invaders and also give support to cell. Cell wall is present in all living organism like bacteria,viruses and fungi.

It has three types which are given below,

Primary Cell Wall

This cell wall is composed of cellulose material and known as primary cell wall.

Middle Wall

Middle is also present between primary and secondary cell wall. It is embedded in primary wall and not easy to differentiate between them.

Secondary Cell Wall

Secondary cell wall is composed of lignin, chitn and some other compounds.

Composition of Organism Cell Wall

Plant Cell Wall

Cell wall of plants is composed of cellulose.

Bacteria Cell Wall

Cell wall of bacteria is composed of peptydoglyogen.

Fungi Cell Wall

Cell wall of fungi is composed of chitin.

Transpiration

Transpiration www.ntsteacher.com The removal or discharge of extra water from the body of plants is known as transpiration. This processes has great important for the removal of extra water. The rate of transpiration increase by every 10 degree centigrade increase in temperature. But, at the 40 to 45 degree centigrade, the stomata closed and rate of transpiration stop. Plants discharge water by different parts of body which are explain below, Lentcular Cells The cells which are present on stem between bark layers are known as lenticular cells. Only 1 to 2% water  release by lenticular cells. Cuticle Cells Cuticle cells are present on leaf and play important role in transpiration. Only 5 to 7% water release through these cuticle cells. Stomata Cells Stomata also play great role in transpiration. 90% water transport through these cells. Tobacco Plant contains 14000 stomata. 40% transpiration takes place through leaf. Guttation In small plants such as grass...
