Morphology of Flowering Plants Test - 8

The leaf base bear two lateral small leaf like structures called stipules.

Bladders of Uricularia and Pitcher of Nepenthes are modification of leaves. They are modified to catch insects that is insectivorous plants.

In Racemose inflorescence, flowers are born in the way that the position of a younger flower is at the apex or distal end while the old flower is placed towards the base and the arrangement is referred to as acropetal arrangement.
So the correct option is 'Distal'

Drupe is an indehiscent fruit in which an outer fleshy part and surrounds a shell of hardened endocarp with a seed. Mango is an example of drupe.

Pomegranate is the fruit which is formed from inferior ovary having succulent testa. Chambered compartment bears many seeds generally red in colour when ripened.

Morphology is the branch of science in which we study about form, size, colour, structure and relative position of various parts of organisms.

Potato is a modified stem as it contain nodes in form of eyes on potato tubers which germinate to produce new potato plants if placed in suitable conditions.

Tinospora develops adventitious roots having chlorophyll and perform photosynthesis. This kind of roots develops from stems andhang in air.

In basalplacentation, the placenta develops at the base of ovary and a single ovule is attached to it,

The edible part of Coconut is endosperm and embryo. The water inside the coconut is cellular embryo and white kernel surrounding it is main edible part that is endosperm.

When the several pistils of thesame flower are separate and the ovary belongs to a single free carpel, it is called apocarpous.

 Duckweeds of the genus Wolffia are the world's smallest flowering plants.

In some plants, like grass,Monsteraand the banyan tree, roots arisefrom parts of the plant other than theradicle and are called adventitious roots.

Monstera has Adventitious roots. These roots arise from parts of the plant other than the radicle.

In recemose inflorescence indefinite growth occurs and bears a number of flowers due to active growing point.

Aleurone layer of maize grain is rich in proteins. It is the outermost layer of the endosperm followed by the inner starchy endosperm.

A seed is made up of a seed coat and an embryo.

Sweet potato and potato are example of analogous organs as they perform same function that is storing food. But potato is a modified stem but sweet potato is modified root.

Stipules are the small lateral outgrowth of the leaf base which protect the young leaf and its axillary buds in young stage. It is a green leafy structure.

The root is covered at the apex by a thimble-like structure called the root cap.

The hilum is a scar on the seed coat through which the developing seeds were attached to the fruit.

The whorl perianth represents undifferentiated calyx and corolla. Its individual units are called tepals.

In epigynous flowers, the margin of thalamus grows upward enclosing the ovary completely and getting fused with it, the other parts of flower arise above the ovary.

Fabaceae are the sources of pulses such as gram, arhar,sem, moong, soyabean.

Zostera is a marine angiospermic plant. The plants have broad leaves that help them in floating on water surface, the root is poorly developed.

Pea tendrils and Opuntia spines are homologous organs because they have the same origin (nodes) and are modifications of leaves but perform different functions. Lemon thorns and cucurbit tendrils are both modifications of stem and are homologous organs.
