| Types of vascular tissue | Present in | |
| I. | Roots | |
| II. | Monocot stems |
A plant with a fibrous root system and leaves with parallel venation would also have:
1. a vascular cambium.
2. secondary xylem and phloem.
3. a cork cambium.
4. none of the above.
| 1. | Casparian strip | 2. | pericycle |
| 3. | apoplast | 4. | symplast |
In the given diagram of section of root of maize, different parts have been indicated by
alphabets. Choose the answer in which these alphabets have been correctly matched
with the parts which they indicate.
| 1. | A = Phloem, B = Xylem, C = Cortex, D = Endodermis, E = Pith, F = Root hair, G =Epidermis |
| 2. | A = Pith, B = Root hair, C = Epiblema, D = Cortex, E = Endodermis, F = Phloem, G= Xylem |
| 3. | A = Root hair, B = Epiblema, C = Cortex, D = Endodermis, E = Pith, F = Xylem, G= Phloem |
| 4. | A = Epiblema, B = Root hair, C = Vascular bundle, D = Cortex, E = Phloem, F =Xylem, G = Pith |
| 1. | The center of the stem or root containing xylem, phloem, and pith |
| 2. | The outer protective layer of the stem or root |
| 3. | The arrangement of vascular bundles in the leaf |
| 4. | The terminal part of the root that absorbs water |
| 1. | only leaves have phloem and only roots have xylem. |
| 2. | root cells have cell walls and leaf cells do not. |
| 3. | a waxy cuticle covers leaves but is absent from roots. |
| 4. | vascular tissue is found in roots but is absent from leaves |
| 1. | D, C, E, A, B | 2. | A, C, E, B, D |
| 3. | C, E, A, D, B | 4. | C, E, D, B, A |
Initiation of lateral roots and vascular cambium during secondary growth take place in ___________.
| 1. | Pith | 2. | Epidermis |
| 3. | Protoxylem | 4. | Pericycle |
In a transverse section of a dicot root, the term stele includes all the following except:
1. Pith
2. Pericycle
3. Vascular bundles
4. Endodermis
| 1. | The innermost layer of the cortex is called hypodermis. |
| 2. | Pericycle is sclerenchymatous. |
| 3. | The pith is large and well developed. |
| 4. | There are usually two to four xylem and phloem patches. |
