| 1. | Sieve Cells | 2. | Albuminous Cells |
| 3. | Tracheids | 4. | Vessels |
| Statement I: | In a dicotyledonous leaf, the adaxial epidermis general bears more stomata than the abaxial epidermis. |
| Statement II: | In a dicotyledonous leaf, the adaxially placed palisade parenchyma is made up of elongated cells, which are arranged vertically and parallel to each other. |
| 1. | Sclereids | 2. | Fibres |
| 3. | Parenchyma | 4. | Collenchyma |
| Statement I: | In collenchyma, cell walls are thickened at corners due to deposition of cellulose, hemicellulose and pectin. |
| Statement II: | Sclerenchyma consists of lignified cell walls and possesses pits. |
| A. | Companion cells help in maintaining the pressure gradient in the sieve tubes. |
| B. | Gymnosperms lack vessels in their xylem |
| C. | The xylem vessels are devoid of cytoplasm |
| D. | Xylem fibres may be septate or aseptate |
| E. | A mature sieve element in phloem possesses cytoplasm, vacuole and nucleus. |

| 1. | Protecting the plant from salt stress. |
| 2. | Increased photosynthesis in monocots. |
| 3. | Providing large spaces for storage of sugars. |
| 4. | Inward curling of leaves in monocots. |
| Statement I: | Parenchyma is living but collenchyma is dead tissue. |
| Statement II: | Gymnosperms lack xylem vessels but presence of xylem vessels is the characteristic of angiosperms. |
