Which of the following is a part of a epidermal layer?
1 Guard cell
2 Root hair
3 Trichomes
4 All of the above
Explanation:
Exp:D The part of epidermal layer is guard cells, trichomes and root hair. Guard cells surrounded by special modified epidermal cells called subsidiory or accessory cells which protect guard cells. Trichomes occur on the shoot trichomes either unicellular as Cannabis Sativa mostly multicellular which may be unbranched as sunflower.

The most primitive type of stele is
1 eustele
2 solentstele
3 protostele
4 siphonostele
Explanation:
Exp:C The most protostele is given by jafferey pith is absent. It is following type. Haplostele:- The central soild pore of xylem is smooth as selaginella crausina. Actinostele:- That is star shaped surrounded by phloem and pericycle as lycopodium serratum and lycopodium psilotum.

Which one is responsible for opening and closing of stomata?
1 Rise in \(\mathrm{pH}\) of guard cell causes hydrolysis of starch
2 Cytokinins and cAMP are requireds
3 Absicisic acid promotes closure
4 All of the above
Explanation:
Exp:D The opening and closing of stomata is regulated by the integration of environmental signals and endogenous hormonal stimuli. When there is the rise in \(\mathrm{pH}\) it causes hydrolysis of starch into sugar which accumulates in guard cell which result in the opening of cell for this mechanism cytokinins and CAMP are required. - Abscisic acid is the stress hormone which results in the close stomata.

Cork cambium is also called
1 phellem
2 phellogen
3 phelloderm
4 none of these
Explanation:
Exp:B Cork cambium also called phellogen. Phellum is also called cork cells. Phelloderm is also called secondary cortex.

The division of an individual vascular cambial cell results in the formation of
1 two xylem mother cells
2 two phloem mother cells
3 one xylem and one phloem mother cell
4 one xylem or one phloem mother cell and one cambium cell.
Explanation:
Exp:C Vascular cambial cell results in the formation of one xylem and one phloem mother cell. Cell division by the cambium produces xylem and phloem. As secondary phloem and xylem tissue accumulates it both increases the girth of the stem and forms wood and bark.
