In a dicot stem, the pericycle is present on the inner side of the endodermis and:
1. | above the phloem, in form of semi-lunar patches of sclerenchyma |
2. | above the xylem, in form of semi-lunar patches of sclerenchyma |
3. | above the phloem, in form of semi-lunar patches of collenchyma |
4. | above the xylem, in form of semi-lunar patches of collenchyma |
In a dicot stem the term 'starch sheath' is used for:
1. | Epidermis with guard cells | 2. | Hypodermis |
3. | Endodermis | 4. | Pericycle |
The vascular bundles in a dicot stem are:
1. conjoint, open with endarch protoxylem
2. conjoint, closed with endarch protoxylem
3. conjoint, open with exarch protoxylem
4. conjoint, closed with exarch protoxylem
The hypodermis of a dicotyledonous stem:
1. | is parenchymatous and synthesizes and stores food |
2. | is collenchymatous and provides mechanical strength to the young stem |
3. | is sclerenchymatous and provides mechanical strength to the young stem |
4. | is parenchymatous and provides mechanical strength to the young stem |
The ring arrangement of vascular bundles is a characteristic feature of:
1. | Monocot stem | 2. | Dicot stem |
3. | Monocot root | 4. | Dicot root |
A conjoint and open vascular bundle will be observed in the transverse section of
1. | Monocot root | 2. | Monocot stem |
3. | Dicot root | 4. | Dicot stem |
