Differentiate between
1 >Parenchyma and sclerenchyma.
2 >Apical and lateral meristematic tissues.
3> Collenchyma and Chlorenchyma
4> Xylem and pholem
Answers
Answer:
1. Parenchyma is made up of cells having very thin cell wall that is uniformly thickened.
Sclerenchyma is made up of a thick and rigid cell wall composed of lignin and other substances.
2. Lateral meristems occur at the cambium and are responsible for secondary growth (i.e. plant widening / thickening)
Apical meristems give rise to new leaves and flowers, while lateral meristems are responsible for the production of bark.
3. Chlorenchyma is a type of parenchyma cells which contains chloroplast. People may confuse between chlorenchyma and collenchyma ,but both are different.
Collenchyma cells are elongated cells with thickened cell walls that provide structure and support for plants. There are four types of collenchyma cells
4. Xylem is the complex tissue of plants, responsible for transporting water and other soluble nutrients to the plants and the flow is unidirectional which is from root to the upper part of the plant,
Phloem is responsible for transporting food produced from photosynthesis from leaves to non-photosynthesizing parts of a plant such as roots and stems.
