You are shown two slides of plant tissue parenchyma and sclerenchyma how
Can you identify the scelernchyma
Answers
Characters of Parenchyma:
1. The cells are generally oval or spherical in shape.
2. These cells are large and are not packed closely, i.e., intercellular spaces are present.
3. Each cell has a large central vacuole and a peripheral cytoplasm with a prominent nucleus.
4. These living cells are found in the soft parts of the plants, i.e., root, stem, leaves, flowers, and fruits.
5. The important functions of these cells are storage of food, filling up spaces between other tissues and providing support to the plant. When they contain chloroplasts as in leaves, they help in the synthesis of food.
Characters of Sclerenchyma:
1. Cells are thick-walled, hard and contain little or no protoplasm.
2. The cells are oval, polygonal and are of different shapes.
3. The cells are dead and the nucleus is absent.
4. These cells are packed closely, i.e., intercellular spaces are absent.
5. The cell wall is evenly thickened with lignin and perforated with pits.
6. They provide strength and rigidity to the plant parts with hardness.
