No. | Tissue | Structural feature | Function |
1. | Collenchyma | Cell walls with high water content | Photosynthesis in young stems |
2. | Parenchyma | Suberized cell walls | Storage of food |
3. | Sclerenchyma | Lignified cell walls | Mechanical strength |
4. | Digestive glands | Dense cytoplasm | Breaking the substrate without water |
A) 1 and 2
B) 2 and 3
C) 1 and 4
D) 1 and 3
Correct Answer: D
Solution :
Collenchyma is a living tissue, consists of non-lignified, cellulosic thick walled cells. Each cells contains an average of about 60.70% of water. The primary function of collenchyma is to provide support but in yong steins, due to presence of chlorophyll it also takes part in photosynthesis. Sclerenchyma tissue consists of lignified. thick walled cells. It provides mechanical support to the plant organs.You need to login to perform this action.
