Collenchyma in plants:
1. Only I, II, and III are correct
2. Only I, II, and IV are correct
3. Only II, III, and IV are correct
4. Only I, III, and IV are correct
| I: | occurs in layers below the epidermis in most of the dicotyledonous plants. |
| II: | consists of cells that are much thickened at the corners due to deposition of cellulose, hemicellulose, and pectin. |
| III: | never contains chloroplasts. |
| IV: | provides mechanical support to the growing parts of the plant such as the young stem and petiole of a leaf. |
