Morphology of Flowering Plants Test - 3

This option is correct. Maize plant contains water-containing schizolysigenous cavities in vascular bundles as it is a monocot.

Radicle is the first part of a seedling (a growing plant embryo) to emerge from the seed during the process of germination.
Roots that grow from any part of plant other than the radicle or its branches are called adventitious roots (L. adventitious— extraordinary). They branch like the tap root. A mass of adventitious roots along with their branches constitute an adventitious root system. Adventitious root system may be underground or aerial. They generally develop from stem nodes, intermodals, leaves, etc.

In the given list, four plants have composite fruits developed from an inflorescence.
They are pineapple, mulberry, jackfruit and fig.

In racemose inflorescence younger flowers are born at the apex or distal end while older flowers are at the base, this type of succession is acropetal succession. Thus, the position of youngest floral bud would be distal.

The correct sequence of the zones of the root in the vertical section from its distal to the proximal end is C, B, E, A, D.
C - Root cap zone
B - Zone of meristems
E - Zone of elongation
A - Root hair zone
D - Zone of maturation

In maize, the fibrous roots is a nodal root system where the roots originate at one of the lower stem nodes of the plants.

The presence of root pockets is a feature of aquatic plants, hence, it is found in Eichhornia.

Podostemon is a hydrophyte and its body is mainly made of roots. It is a genus of plants in the family Podostemaceae.

Bulbil is a reduced stem. It is a special modification for reproduction of the plant. Example: Agave and Lily.

Potatoes are borne on the axil of scaly leaves. They possess small buds in the axil of scaly leaves from where new potatoes are produced.
