Reproduction in Organisms Questions — NEET Biology

Q1

Vegetative reproduction of Agave occurs through

A rhizome

B stolon

C bulbils

D sucker

Correct Answer

Option C

Solution

(c) Agave reproduces vegetatively through bulbils — modified buds that form new plants.

Q2

A population of genetically identical individuals obtained from asexual reproduction is

A Callus

B Clone

C Deme

D Aggregate

Correct Answer

Option B

Solution

(b) A clone is a population of genetically identical organisms produced by asexual reproduction.

Q3

During regeneration, modification of an organ into another organ is known as

A Morphogenesis

B Epimorphosis

C Morphallaxis

D Accretionary growth

Correct Answer

Option B

Solution

(b) Epimorphosis: new cells proliferate from a blastema to form the missing structure.

Q4

What is true for cleavage?

A Size of embryo increases

B Size of cells decrease

C Size of cells increase

D Size of embryo decreases

Correct Answer

Option B

Solution

(b) Cleavage involves rapid cell division without growth — cell number increases, cell size decreases.

Q5

Offsets are produced by

A Meiotic divisions

B Mitotic divisions

C Parthenogenesis

D Parthenocarpy

Correct Answer

Option B

Solution

(b) Offsets are vegetative propagules produced by mitotic divisions — genetically identical to parent.

Q6

Which of the following pairs is not correctly matched?

A Rhizome - Banana

B Binary fission - Sargassum

C Conidia - Penicillium

D Offset - Water hyacinth

Correct Answer

Option B

Solution

(b) Sargassum reproduces by fragmentation, not binary fission.

Q7

In ginger vegetative propagation occurs through

A Offsets

B Bulbils

C Runners

D Rhizome

Correct Answer

Option D

Solution

(d) Ginger propagates through underground rhizomes.

Q8

Cells become variable in morphology and function in different regions of embryo. The process is

A differentiation

B metamorphosis

C organisation

D rearrangement

Correct Answer

Option A

Solution

(a) Differentiation: cells acquire specialized form and function during development.

Q9

A perennial plant differs from biennial in

A having underground perennating structure

B having asexual reproductive structures

C being tree species

D not dying after seasonal production of flowers

Correct Answer

Option D

Solution

(d) Perennials survive and flower multiple times across more than two years.

Q10

In an egg, the type of cleavage is determined by

A shape and size of the sperm

B size and location of the nucleus

C amount and distribution of yolk

D number of egg membranes

Correct Answer

Option C

Solution

(c) Amount and distribution of yolk determines the type (holoblastic/meroblastic) and depth of cleavage.
