These are difference between collenchyma and sclerenchyma.
Collenchyma |
Sclerenchyma |
1. The cells of collenchyma are living and have the cytoplasm and the nucleus. |
1. The cells are dead. They do not have the cytoplasm and the nucleus. |
2. The collenchyma cells have thickening of cellulose and pectin at the corner of its cells. |
2. The sclerenchymatous cells do not have such thickenings. |
3. They provide mechanical support and elasticity to the plant organ. |
3. They mainly provide mechanical support to plant and rigidity to the plant. |
4. Collenchyma cells may contain chlorophyll and can also help in the manufacture of starch and sugar. |

Take four peeled potato halves and hollow each one out to make potato cups. One of these potato cups should be made from a boiled potato. Put each potato cup in a trough containing water. Now,
(a) keep cup A empty
(b) put one teaspoon sugar in cup B
(c) put one teaspoon salt in cup C
(d) put one teaspoon sugar in boiled potato cup D.
Keep this setup for two hours. Then observe the four potato cups and answer the following :
(i) Explain why water gathers in the hollowed portion of B and C?
(ii) Why is potato A necessary for this experiment?
(iii) Explain why water does not gather in the hollowed out portions of A and D.
