define parenchyma, collenchyma and scalenchyma plz answer fast
Answers
Explanation:
hope it will help you parent parenchyma tissue is made up of parenchymatous cells these cells are living and capable of division the cells have thin walled the cell wall is made up of cellulose some parenchyma contain chlorophyll are called chlorenchyma they help in photosynthesis parent timer containing air cavities called erenchyma, they help aquatic plants to float the cells are isodiametric or rounded in shape intercellular space may be present but vacuoles may or may not be present it is found in cortex of stem mesophyll of leaves and ground tissue of root.
collencyma cells are a longer Ted irregular shaped cell wall is thicker at the corners due to the position of cellulose vacuoles are large and nucleus is small in size vacuoles are found in the flexible parts of the plant which are banned intercellular spaces are generally absent it provides flexibility it is found in such that which can be bend and it also provides mechanical support
sclerenchyma cell wall is thick and it is made up of Lignin nucleus and cytoplasm are absent it may be two types clarets and fibres they are present in hard covering of seeds nodes and husk of coconut it gives mechanical support it also protects plant parts
hope it would help you
Answer:
PARENCHYMA :-
❉The cells of parenchyma aree soft,thin walled and loosely packed.
❉They store food ,bears chloroplasts contain larger cavities.
❉Cell wall is primary made up of cellulose.
❉Cells are oval , round and rectangular in shape.
COLLENCHYMA :-
❉The cells of collenchyma are thick walled and compactly arranged.
❉They give mechanical strength in young tissue of stem.
❉Cell wall has deposition of extra cellulose.
❉Cells are elongated , round and spherical in shape.
SCLARENCHYMA :-
❉ It is a dead tissue.
❉Cells are thick walled.
❉Inter cellular spaces are absent.
❉It provides mechanical strength.
