write distinct feature of parenchyma ,collenchyma and sclerenchyma
Answers
Answer:
Explanation:
Features of parenchyma:
They form basic packing tissue.
Cells of this tissue are relatively unspecialised and may be oval, rounded or elongated in shape.
Their cell walls are thin.
These cells are living.
They show large intercellular spaces.
Cytoplasm is dense with a small nucleus.
The celss possess a large central vacuole.
Parenchyma provides support to plants and also stores food
Features of Sclerenchyma:
Their cells are dead.
Cells are long and narrow.
Cells are empty and devoid of protoplasm.
Cell walls are highly thickened due to lignin deposition.
There is no internal space inside the cell.
Cells are closely packed, with no inter cellular spaces.
It is a strengthening or mechanical tissue.
Features of collenchyma:
They possess living cells.
It shows deposition of extra cellulose at the corners of the cells.
Inter cellular spaces are generally absent.
Their cells are elongated in shape.
according to my text book this is the answer
Answer:
Parenchyma cells are found in every soft part of the plant, but collenchyma cells are found in specific part of the plant like leaves, stems, and petioles, whereas sclerenchyma cells are found in mature parts of the plants or trees. Parenchyma has a thin cell wall of their cells, and are made up of cellulose. Parenchyma cells are notable for their thin walls, and for being alive at maturity. Collenchyma cells tend to develop thicker secondary cell walls, to support structure. Sclerenchyma cells get both thicker walls and die off at maturity, producing tissues like bark and vascular tissue
