BIOLOGY M.C.Q (1 Marks)

In the given diagram '$C$' represent radicle

Solanaceae $\rightarrow$ Polyandrous, epipetalous and dithecous anther.

Liliaceae $\rightarrow$ Polyandrous, epiphyllous and dithecous anther.

Internodes do not elongate and the axis gets condensed. The apex produces different kinds of floral appendages laterally at the successive nodes instead of leaves.

Therefore, both $A$ and $R$ are true and $R$ is correct explanation of $A$.

This also accompanies the sulphur containing glucosides which hydrolyses them in to glucose and isothiocynates $(oil)$.

Androecium indefinite stamens, gynoecium pentacarpellary to indefinite. syncarpous, ovary superior.

It can be accrescent (sepals grow in size, remain green and may cover the fruit, e.g.,$ Brinjal, Chillies$) or marcescent (sepals do not grow with the growth of fruit and become dry, e.g., $Guava, Piper$).

filaments of $ 9 $ stamens are fused forming one bundle and the other bundle is represented by the filament of the tenth free stamen $ (A_1 + (9)).$

Placentae highly swollen, ovules are maximum per locule in this family.

In tetradynamous conditions four stamens remain long and two short.

Its root and leaves are used as vegetables.

plants mostly herbs stem with latex / oil ducts and most evolved and advanced among dicot.

called epicalyx $(hypocalyx)$ which is modification of bracteoles is characteristic of the Malvaceae flowers.

Thalamus is conical or convex with gynoecium at top and other part below it,

ovary is superior and other parts inferior.

e.g., Liliaceae, Malvaceae and Solanaceae.

Hypocotyl elongates and pushes the radicle but the seed and fruit hangs like Damocle's sword from the tree.

It is found in mangroves (e.g., $Rhizophora, Sonneratia$).

In albuminous seeds, embryo not consumed all endosperm. So it persists in the mature seed.

In these seeds food stored in endosperm.
