Copy the picture given above and mark the following : Connective tissue Endothecium Tapetum Sporogenous tissue

Developing pollen obtains its nutrition from (a) Endothecium (b) Tapetum (c) Epidermis (d) Middle layer

Study the following lists {:("List-I",,"List-II"),("A. Endothecium",,"I. present between the pollen sacs"),("B.Tapetum",,"II. Fibrous thickenings"),("C.Stomium",,"III. Outer layer of microsporangium"),("D. Sporogenous tissue ",,"IV. Nourishes the pollen grains"),("",,"V. Centre of microsporangium"):}

Statement -1 : The innermost layer of microsporangium is tapetum. Statement -2 : Glandular tapetum provides nourishment to developing microspores.

Statement -1 : The innermost layer of microsporangium is tapetum. Statement -2 : Glandular tapetum provides nourishment to developing microspores.

Select the incorrect statement w.r.t tapetum. (a) Cells of tapetum are polyploid. (b) Amoeboid tapetum provides ubisch bodies which helps in ornamentation of exine. (C) Tapetal cells show increase in their DNA content. (d) Innermost layer of anther surrounds the sporogenous tissue. (e) Glandular tapetum secretes sporopollenin, pollenkit and compatibility proteins

Sporogenous tissue gets its nourishment from layer of anther wall, which can release not only enzymes but also hormones? (A) Middle layer (B) Epidermis (C) Tapetum (D) Endothecium
