Plant Tissure Flashcards
a group of cells having a common origin and usually performing a common function in a plant body.
Plant tissue
The tissue which is composed of immature and undifferentiated cells which are either in a continuous state of division or retain the power of division.
The cells produced by meristem later transform into permanent cells.
Meristematic tissue
It is found at the tip of root or shoot i.e apical position.
The_______ __________ tissue transforms into primary permanent tissue and help in the increase length of plant body.
Apical meristem
The meristematic tissue which is _______ in the position of root and stem.
It helps to increase the diameter of plant.
Lateral meristem
It is _________ between permanent tissues.
Their position is either at the base of the leaf, at the base of node or after base of internode
Intercalary meristem
The tissue which is composed of mature and differentiated cell that has already undergon
growth and has assume definite size, shape and function
The cell of permanent tissue have lost the power of division temporarily or permanently.
Thin walled are usually living whereas thick walled are dead.
Permanent tissue
The most common type of simple permanent tissue present in all the plants.
• It is composed of thin wall living cell and cell wall is made of cellulose.
Intercellular space is present
Parenchyma
When parenchyma cell contain chlorophyll, they are said
Chlorenchyma
The parenchyma cells in the cortex of aquatic plant encloses large air spaces and cavities called……
Arenchyma
a. The main function of __________ cell is to store food material.
b. The chlorenchyma cells take part in photosynthesis.
C. The ___________helps plant to remain floating on surface of water by providing buoyancy.
Parenchyma
It is composed of living thick-walled cells.
The thickening is due to deposition of cellulose, hemicellulose or pectin.
Collenchyma
It is the chief mechanical tissue of the plant body composed of highly thick- walled cell.
The thickening of cell wall is due to deposition of cellulose or lignin or both
Sclerenchyma
collection of similar cells performing similar function
Simple tissue
collection of dissimilar cells which perform cell function. It forms vascular or conducting tissue in the plant
Complex tissue
It conducts mineral salt and water from roots to upper region.
Xylem
