Botany and Plant Science

There are two types of vascular tissues present in the plants viz. Xylem and Phloem. Xylem is responsible for transport of water and some minerals. Phloem is responsible for transport of food and minerals.

Plants absorb their mineral salt supply from the soil through the roots from the zones of elongation and root hair. The minerals are absorbed as ions which are accumulated by the plants against their concentration in the soil.

Monocarpic plants are those that flowers once during their Iife time, set seeds and then die, e.g.,bamboos.

Salvadora is known for having anomalous secondary growth, which includes the presence of internal and included phloem within the stem.

In Peperomia, leaf cuttings are typically prepared using the entire leaf, including the petiole, to ensure successful propagation.

Epiphyllous buds are adventitious buds that arise from the surface of a leaf. They are a form of vegetative propagation found in plants like Bryophyllum.

A) The midrib is the large strong central vein in the middle of the leaf.
B) The lamina is the broad green part of the leaf in which photosynthesis takes place.
C) Leaf base is the lowermost part of the leaf from where it attaches to stem or branch.
D) Stamen is the male reproductive part present on a flower.
So the correct option is 'Stamen'.

A simple pinnate compound leaf is one where the leaflets are attached directly to the rachis, which is known as unipinnate.

In Opuntia (cactus), the areoles are specialized structures that represent modified axillary buds or nodes, from which spines or flowers grow.

Venation is the arrangement of veins on the leaves. It is basically of 2 types, reticulate and parallel. Reticulate venation involves irregular distribution of veins to form a network. Parallel venation involves the veins running parallel to each other. In pinnate or unicostate venation, the lamina has a single principal vein or midrib. It produces lateral veins. In palmate or multicostate venation, lamina has more than one principal vein. In Canna, the venation is pinnately parallel. 

Compound leaves are of two types, namely pinnately compound leaves and palmately compound leaves. In palmately compound leaf, the leaflets are arranged at the tip of the petiole. It is further divided into 5 types depending upon the number of leaflets present at the tip of the petiole.

In unifoliate, there is only one terminal leaflet is attached at the top of petiole. Example includes citrus.

In bifoliate, two leaflets are attached side by side at the terminal end of petiole. Example includes Balanites roxburghii.

In trifoliate, three terminal leaflets are attached at the terminal end of petiole. Example includes Aegle marmelos.

In quadrifoliate, four leaflets are attached to the tip of petiole. Example includes Paris quadrifolia.

In multifoliate, five or more leaflets are present at the tip of petiole in the form of fingers of the palm. Example includes Parthenium (common weed).

Thus, the correct answer is 'Multifoliate.'

Parallel venation, in which veins run parallel to one another from base to the tips of the leaf. Reticulate venation in which veins are arranged in a net like a pattern on both sides.
