An ovule which becomes curved so that the nucellus and embryo sac lies at right angles to the funicle is :-
1 Campylotropous
2 Anatropous
3 Orthotropous
4 Hemitropous
Explanation:
D An ovule which becomes curved so that the nucellus and embryo sac lies at right angles to the funicle is a hemitropous ovule. The body of the ovule is placed transversely at right angles to the funicle and the micropyle and chalaza lie in one straight line in hemitropous ovules. - Ovule have been separated into (6) categories based on their shapes.

Pappus is modified
1 calyx
2 corolla
3 bracts
4 gynoecium
Explanation:
A The Pappus is modified calyx or sepals. In Asteraceae the pappus is the part of an individual floret that surrounds the base of the corolla tube in flower.

Trimerous flower, superior ovary and axile placentation is characteristics of
1 Liliaceae
2 Cucurbitaceae
3 Solanaceae
4 Compositae
Explanation:
A Trimerous flower, superior ovary and axile placentation is characteristics of Lilliaceae. The plants owned by this family are monocotyledonous plants. They are extensively distributed worldwide. Trimerous flowers have floral appendages or whorls in threes, like three petals, three sepals etc. In axile placentation the placenta is present in axial position and the ovules are attached to in the multilocular ovary.

3 Outer whorl of four larger stamens and inner whorl of two smaller stamens
4 Outer whorl of two smaller stamens and inner whorl of four larger stamens
Explanation:
D The common name of Brassica campestris is mustard. It is a characteristic of Brassica family and found in Brassica campestris. Tetradynamous is a floral condition in which the flower contains 6 staments out of which 4 are longer and two are shorter.

Long filamentous threads protruding at the end of a young cob of maize are-
1 Anthers
2 Styles
3 Ovaries
4 Hairs
Explanation:
B In maize the male inflorescence occupies the terminal position on the main axis, whereas the female inflorescence (ear or cob) is borne on modified lateral branches in the axils of leaves. The ear producing branch has short internodes and bears a female spike at its apex. Each spikelet has a pair of small membranous glumes and two florets. The feathery styles of the female florets are long and emerge out of the cobs to expose stigma for wind pollination.
