Test: Morphology of Flowering Plants - 1 - NEET MCQ

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

Topic in NCERT: THE LEAF

Line in NCERT: "The leaf is attached to the stem by the leaf base and may bear two lateral small leaf like structures called stipules."

In Cymose type of inflorescence the main axis terminates in a flower, hence is limited in growth. The flowers are borne in a basipetal succession.

Topic in NCERT: THE INFLORESCENCE

Line in NCERT: "In cymose type of inflorescence the main axis terminates in a flower, hence is limited in growth. The flowers are borne in a basipetal order."

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

Topic in NCERT: MORPHOLOGY OF FLOWERING PLANTS

Line in NCERT: "The wide range in the structure of higher plants will never fail to fascinate us. Even though the angiosperms show such a large diversity in external structure or morphology, they are all characterised by presence of roots, stems, leaves, flowers and fruits."

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

Topic in NCERT: placentation

Line in NCERT: "In basal placentation, the placenta develops at the base of ovary and a single ovule is attached to it, as in sunflower, marigold."

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

Topic in NCERT: THE INFLORESCENCE

Line in NCERT: "In racemose type of inflorescences the main axis continues to grow, the flowers are borne laterally in an acropetal succession."

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

Topic in NCERT: Aleurone layer

Line in NCERT: "The outer covering of endosperm separates the embryo by a proteinous layer called aleurone layer."

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

Topic in NCERT: THE SEED

Line in NCERT: "The ovules after fertilisation, develop into seeds. A seed is made up of a seed coat and an embryo. The embryo is made up of a radicle, an embryonal axis and one (as in wheat, maize) or two cotyledons (as in gram and pea)."

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

Topic in NCERT: Structure of a Dicotyledonous Seed

Line in NCERT: "The hilum is a scar on the seed coat through which the developing seeds were attached to the fruit."

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.

Topic in NCERT: Position of floral parts on thalamus

Line in NCERT: "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.

The cells proximal (towards the root tip) to the meristematic zone in the root tip represent the zone of cell elongation. The root tip is composed of several distinct zones, including the meristematic zone, zone of cell elongation, zone of differentiation, and zone of maturation. These zones are responsible for different processes involved in root growth and development.

Topic in NCERT: Regions of the Root

Line in NCERT: "The cells proximal to this region undergo rapid elongation and enlargement and are responsible for the growth of the root in length. This region is called the region of elongation."

A: In a pinnately compound leaf a number of leaflets are present on a common axis, the rachis, which represents the midrib of the leaf as in neem.
B: In palmately compound leaves, the leaflets are attached at a common point, i.e., at the tip of petiole, as in silk cotton.

Topic in NCERT: Types of Leaves

Line in NCERT: "A leaf is said to be simple, when its lamina is entire or when incised, the incisions do not touch the midrib. When the incisions of the lamina reach up to the midrib breaking it into a number of leaflets, the leaf is called compound. The compound leaves may be of two types. In a pinnately compound leaf a number of leaflets are present on a common axis, the rachis, which represents the midrib of the leaf as in neem. In palmately compound leaves, the leaflets are attached at a common point, i.e., at the tip of petiole, as in silk cotton."

Drupes, also known as stone fruits, are characterized by having a hard and stony endocarp. The endocarp is the innermost layer of the fruit wall and is often hard and stony in drupes, enclosing the seed(s) within. Examples of drupes include fruits like peach, plum, cherry, and mango, where the endocarp is hard and stony, giving them the name "stone fruits".
