Tissue |
The group of cells performing some collective function is called tissue. |
|
Simple tissues |
The tissues with similar type of cells are called simple tissues. |
|
Compound tissues |
The tissues wtith different types of cells are called compound tissues. |
|
Parenchyma |
The simple tissues with cells having thin and elastic walls are called parenchyma. |
|
Collenchyma |
The parenchyma cells with uneven angular thickening which support young growing part of plant are called collenchyma. |
|
Sclerenchyma |
The lignified tissues which lack protoplast at maturity are called sclerenchvma. |
|
Fiber |
Very long and narrow sclerenchymatous cells with tapering ends are fibers. |
|
Sclereids |
The variable shaped sclerenchymatous cells with strongly lignified wall having simple pits are called sclereids. |
|
Tracheary elements |
The specialized water and salt conducting cells of xylem are called tracheary elements. |
|
Vessel membranes |
The tracheary elements which are short, wide and with perforated end walls are called vessel members. |
|
Tracheids |
The tracheary elements which are elongated tube like w ith tapering ends are called tracheids. |
|
Primary xylem |
The xylems produced as a result of primary growth are called primary xylem. |
|
Protoxylem |
The early primary xylems are called protoxy lem. |
|
Phloem |
Phloems are living conducting tissues. They conduct prepared food form leaves to ditTerent part of the plant. |
