(a) Draw a sectional view of human ovary. Label the following parts:
(i) Primary follicle
(ii) Secondary oocyte
(iii) Graafian follicle
(iv) Corpus luteum
(b) Name the hormones influencing follicular development of corpus luteum.
OR
(a) Draw an L.S. of pistil showing pollen tube entering into the embryo sac. Label the following:
(i) Nucellus
(ii) Antipodals
(iii) Synergids
(iv) Micropyle
(b) Write the functions of the following :
(i) Synergids
(ii) Micropyle
a)

Figure. Diagrammatic Section view of ovary
b) Gonadotropins i.e., LH (luteinising hormone) and FHS (follicle stimulating hormone).
OR
a)

b)Function of synergids- The synergid cell guides the pollen tube to enter into the ovule through the micropyle.
(ii) Functions of micropyle-The micropyle is remaining as small pore in the seed coat. During seed germination, this facilitates the entry of oxygen and water into the seed.
