Q. No.Plant tissues are classified into two main groups, meristematic and permanent, mainly on the basis of:
1. their location
2. time of their origin during the plant life
3. capability of division
4. degree of differentiation
Identify the incorrect statement regarding the anatomy of flowering plants:
1. Plants have cells as the basic unit.
2. Different organs in plants show differences in their internal structure.
3. Within angiosperms, dicots and monocots are anatomically different.
4. Adaptations to diverse environments are seen in external structures only.
The meristem which occurs between mature tissues in a plant body is known as:
| 1. Secondary meristem | 2. Intercalary meristem |
| 3. Lateral meristem | 4. Cylindrical meristems |
Permanent tissues in a plant body are formed following division of cells in:
1. Primary meristems only
2. Secondary meristems only
3. Both primary and secondary meristems
4. Neither primary nor secondary meristems
The sieve tube elements and the companion cells are connected by:
1. sieve pores in their common transverse wall
2. sieve pores in their common longitudinal wall
3. pit fields in their common longitudinal wall
4. pit fields in their common transverse wall
Cells of this tissue are living and show angular wall thickening. They also provide mechanical support. The tissue is
| 1. Xylem | 2. Sclerenchyma |
| 3. Collenchyma | 4. Epidermis |
In which of the following pairs of parts of a flowering plant is epidermis absent?
| 1. | Root tip and shoot tip | 2. | Shoot bud and floral bud |
| 3. | Ovule and seed | 4. | Petiole and pedicel |
The terminal and axillary buds arise from
| 1. apical meristem | 2. intercalary meristem |
| 3. lateral meristem | 4. parenchyma |

Which of the following is true about tracheids and vessels
1. Tracheids are multicellular with narrow lumen
2. Tracheids are unicellular with wide lumen
3. Vessels are multicellular with wide lumen
4. Vessels are unicellular with narrow lumen
