2. Differentiate the following (AS 1)
- Meristematic tissue and Ground tissue
- Apical meristem and lateral meristem
- Parenchyma and collenchyma
Sclerenchyma and parenchyma
- Xylem and phloem
- Epidermis and bark
Answers
Answer:
•••Xylem and phloem:
Xylem transports only minerals and waters from the roots. Phloem transports food materials that are prepared by the green parts of the plants to other parts of the plant. Xylem is the dead tissues at maturity, but no cell contents. Phloem is the living tissue, but not with the nucleus.
•••Epidermis and Bark:
Bark is the outer covering of the plant made of sclerenchyma.
Epidermis is the inner layer of the bark
•••Parenchyma and sclerenchyma:
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 and collenchyma:
Parenchyma has a thin cell wall of their cells, and are made up of cellulose. Whereas collenchyma cells have an uneven cell wall made up of pectin and hemicellulose. There is a hard and thick cell wall present of the sclerenchyma cells, which is made up of the lignin.
•••Apical meristem and lateral meristem:
Primary or apical meristem is the tissue from which the main stem of a plant arises while lateral meristem is the one from which the plant grows laterally. ... Apical meristems are responsible for the primary growth of the stems and roots of the plants and hence they will help increase length and height of the plant.
Meristematic tissue and Ground tissue:
Meristematic tissue and ground tissue are two types of tissues found in plants. ... The cells in the ground tissue are incapable of dividing. The main difference between meristematic tissue and ground tissue is their location, function, and the ability to divide.
