3. | Both Statement I and Statement II are correct and Statement II correctly explains Statement I |
4. | Only Statement II is correct |
I: | Plant cells possess cell walls, plastids and a large central vacuole which are absent in animal cells. |
II: | Animal cells have centrioles which are absent in almost all plant cells. |
1. | Cell wall helps in cell-to-cell interaction and provides barrier to undesirable macromolecules. |
2. | Cell wall consists of cellulose, hemicellulose, pectins and proteins. |
3. | The primary wall is capable of growth. |
4. | The secondary wall is formed on the outer (towards middle lamella) side of the cell. |
1. | Cell wall is made up of peptidoglycans |
2. | 80S type of ribosomes are present in the cytoplasm |
3. | Mitochondria contain circular DNA |
