Botany and Plant Science

Here the micropyle, chalaza and funicle are in a straight line. This is the most primitive type of ovule, e.g. piper, polygonum, cycas.

It is effective mechanical tissue of growing organs where it can give strength and elasticity.

Middle lamella is colloidal in nature. It is composed of magnesium and calcium pectate.

These are found in the stem and leaf sheaths of many monocots particularly grass.

Velamen is a spongy, multiple epidermis that covers the roots of some epiphytic or semiepiphytic plants, such as orchids.

When phloem and cambium are present on both sides of xylem, the vascular bundles are called bicollateral vascular bundles.

The older, nonliving central wood of a tree or woody plant, usually darker and harder than the younger sapwood. It is also called duramen.

A tangential section is a longitudinal section of a stem where the section is perpendicular to the tangent or radius of the stem.

Here, solid core of xylem is surrounded by phloem.

Cleistogamy or automatic self-pollination describes the trait of certain plants to propagate by using non-opening, self-pollinating flowers.

Embryo sac is the female gametophyte in which the diploid embryo develops.

The scion is a cutting that is located on the sides of the plant. This cutting is most commonly grafted onto the root system of another plant. The scion is selected to be cut especially for its flowers, stems, leaves, flowers and fruits. The genes in the scion are able to be duplicated by the scion plant.

This is the correct option as a flower is not involved in vegetative reproduction. Only the vegetative parts of a plant take part in it, i.e. root, stem and leaf.

This is the correct option. Ferns and mosses are non-flowering and reproduce by the method of spore formation.

This is the correct option. Stamen is the male reproductive part of a flower.
