If the dicot stem is stained for starch. The most intense colouration would develop in:
1 epiblema
2 phloem
3 endodermis
4 pith
Explanation:
Exp:C The inner most layer of the cortex is the endodermis. It consisting of barrel shaped elongated compact cells having no inter cellular spaces. It contain starch grain and thus the endodermis may be termed as starch sheath.

In dicot stem secondary growth is due to the activity of:
1 apical meristem
2 lateral meristem
3 cork
4 bark
Explanation:
Exp:B Lateral meristems are seen at the lateral sides of roots and stem in plant. It consists of two meristems called cork cambium and vascular cambium. In a dicot stem, secondary growth occurs due to lateral meristem.

In dicot stem, vascular bundles are
1 Numerous scattered
2 Arranged in a ring
3 Without cambium
4 Surrounded by bundle sheath
Explanation:
Exp:B The vascular bundles of monocotyledonous stem are like those of dicotyledonous stem in consisting of xylem towards the centre of the stele and phloem towards the periphery. The vascular bundles of monocotyledonous stem do not passes a cambium layer. Which found in dicotyledonous stems. Each bundle remains more or less completely surrounded by a sheath of sclerenchyma cells and bundle sheath.

Chronological sequence of cellular layers from the periphery towards the cortex in an old dicot stem is
1 epidermis, hypodermis, cortex, endodermis
2 epidermis, phellem, phellogen, phelloderm
3 epidermis, hypodermis, phellogen, phelloderm
4 epidermis, phellogen, phellem, endodermis
Explanation:
Exp:B The transverse section of typical young dicotyledonous stem shows that the epidermis is the outer most protective layer of stem covered with a thin layer of cuticle. It may be bear trichomes and few stomata, the cells arranged in multiple layers between epidermis and pericycle constitute of a few layers of collenchymatous cells. Just below the epidermis which provide mechanical strength to young stem. Cortical layers below hypodermis consist of rounded, then walled parenchymatous cells with consipicuous inter cellular spaces the cells of the endodermis are rich in starch grains.
