explain, where they are presnt with functions.
Parenchyma, Collenchyma, Sclerenchyma
Answers
Answer:
The function of parenchyma cells is in the storage of foods, in gaseous exchange, and in photosynthesis, while collenchyma cells provide mechanical support and elasticity to the plant, the sclerenchyma cells provides mechanical support to the plant. It also supports transportation of water and nutrients to the plants

Answer:
Parenchyma : The cells of this tissue are living, with thin cell walls. Cells can be oval or round in shape. They have a large central vacuole and a dense cytoplasm. The parenchyma tissue is located in the soft parts of the plant such as cortex and pith. It mainly acts as a packing tissue, providing mechanical support. It also helps in the storage of food. Based on the specific functions, parenchyma can be further classified into Aerenchyma and Chlorenchyma.
Collenchyma : These cells are living cells and have an elongated shape. The corners of the cell wall are thickened. There is very little intercellular space present. The collenchyma tissue can be located in the leaf stalks, below the epidermis etc. Its main function is to provide flexibility to the plants as well as mechanical support.
Sclerenchyma: The cells of the sclerenchyma tissue are dead. The cell wall is very thick due to the deposition of lignin. The cells of this tissue can be in different shapes and sizes. They are generally located in the leaf veins, hard coverings of the seeds and can also be found surrounding the vascular bundle.
