Differentiate between parenchyma and collenchyma.
in a table format please
Answers
Answer:
Parenchyma cells are the type of living plant cells, which are known for healing and repair mechanism, and food storage. Collenchyma cells are known for providing mechanical support to the plants, by protecting the delicate inner part of the plant. Sclerenchyma cells are the matured dead cells and are found in wooden part or hard stem of the plant.

here's your answer ⭐
Listed below are some differences between these cells:
What it means
Parenchyma Cells: Originate from ground and protoderm meristems
Collenchyma Cells : Originate from pro-cambium. Epidermal layer of plants are composed of collenchyma cells.
Location
Parenchyma Cells: Found in every delicate plant part
Collenchyma Cells : Specifically found in leaves, stems and petioles
Cell type
Parenchyma Cells: Living and unspecialized cells
Collenchyma Cells : Living and specialized cells
Shape of the cell
Parenchyma Cells: Isodiametric generally,
Collenchyma Cells : may vary in shape Elongated cells
Cell wall
Parenchyma Cells: Present and thin-walled
Made of cellulose
Collenchyma Cells : Present, uneven cell wall
Made of pectin and hemicellulose
Intercellular spaces
Parenchyma Cells: Present between cells
Collenchyma Cells : Less space present
Function
Parenchyma Cells: Food storage
Gaseous exchange
Photosynthesis
Collenchyma Cells : Renders mechanical support
Elasticity
hope it helps you
