2. Differenciate in between 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:
Apical meristem and lateral meristem
1) apical meristem: location =at the tip of root and stem , function = increase the length of the root and stem .
2)lateral meristem : location =lateral sides of root and stem , function = increase diameter of root and stem

Answer:
meristematic tissue is the group of cells that has the ability to easily divide.
ground tissue are tissue of plantother in epidermis and vascular tissue.
APICAL MERISTEM is - it is present in growing tip of the stem and roots and in creases the length
LATERAL MERISTEM- it is present at the lateral side of stem and roots it will help to growth and it will increases truth
PARENCHYMA- it is consisting a thin cells wall with inter cellular spaces and no deposit are observed .
COLLENCHYMA- it is consisting a thick cell walls without a inter cellular spaces but they have a deposits of pectin .
SCALERENCHYMA- it has cells that both primary and secondary cell walls it has ability to have very low photosynthetic.
PARENCHYMA- it has cells that have thin primary cell walls and lack of secondary cell walls and it is easily allow to molicules to enter in the cell
XYLEM- this tissue contains XYLEM vessels , tracheids and it helps the transportation water from soil to roots and to all of the body
PHOLEM- it contains PHOLEM- vessels and companion cells and it transportation food and water to all of the body
EPIDERMIS- is the inner layer of bark
BARK- is outer layer of covering plant of mode of schelrrychma
