The term ‘clone’ cannot be applied to offspring formed by sexual reproduction because:

Offspring do not possess exact copies of parental DNA. DNA of only one parent is copied and passed on to the offspring. Offspring are formed at different times DNA of parent and DNA of offspring are completely different.

Amoeba and Yeast reproduce asexually by fission and budding respectively, because they are:

Microscopic organisms Heterotrophic organisms Unicellular organisms Uninucleate organisms.

A few statements with regard to sexual reproduction are given below: (i) Sexual reproduction does not always require two individuals. (ii) Sexual reproduction generally involves gametic fusion. (iii) Meiosis never occurs during sexual reproduction (Iv) External fertilisation is a rule during sexual reproduction. Choose the correct statements from the options below:

i and iv i and ii ii and iii i and iv

A few statements describing certain features of reproduction are given below:(i) Gametic fusion takes place(ii) Transfer of genetic material takes place(iii) Reduction division takes place(iv) Progeny has some resemblance with parents. Select the options that are true for both asexual and sexual reproduction from the options given below:

i and iii

ii and iii

ii and iv

i and iii

A multicellular, filamentous alga exhibits a type of sexual life cycle in which the meiotic division occurs after the formation of zygote. The adult filament of this alga has

Haploid vegetative cells and Diploid gametangia

Diploid vegetative cells and Diploid gametangia

Diploid vegetative cells and Haploid gametangia

Haploid vegetative cells and Haploid gametangia.

Pollination by Bat is called :

Omithorphily Entemophily Cheropterophily Hydrophily

Anemophily takes place by:

By Bird By Bat By Snail By Wind

Entemophily take place by

By Bird By Bat By Wind By Insect

In higher plants, meiosis occurs?

During formation of gametes During fertilization During embryogenesis In seeds

Earthworm is:

Unisexual Bisexual Asexual Neutral

In animals, juvenile phase is followed by,

reproductive phase senescent phase old age vegetative phase.

Vegetative propagation in Pistia occurs by

sucker offset runner rhizome

The most significant feature of vegetative propagation is that

It is a method of producing a large number of individuals genetically identical to the parent.

It is a method of producing a large number of individuals genetically different from the parent.

It ensures that the progeny individuals are resistant to diseases and pests.

It is an age old practice.

The terms homothallic and monoecious are used to denote

Unisexual condition

Bisexual condition

Staminate flowers

Pistillate flowers.

External fertilisation occurs in majority of

Fungi

Liverworts

Algae

Mosses

Appearance of vegetative propagules from the nodes of plants such as sugarcane and ginger is mainly because

Nodes have meristematic cells Nodes are located near the soil Nodes have non-photosynthetic cells Nodes are shorter than internodes

Offspring formed by sexual reproduction exhibit more variation than those formed by Asexual reproduction because

Gametes of parents have qualitatively different genetic composition Genetic material comes from parents of two different species Greater amount of DNA is involved in sexual reproduction Sexual reproduction is a lengthy process

There is no natural death in single celled organisms like Amoeba and bacteria because:

Parental body is distributed among the offspring They are microscopic They reproduce by binary fission They cannot reproduce sexually

There are various types of reproduction. The type of reproduction adopted by an organism depends on

The organism’s habitat, physiology and genetic makeup Morphology and physiology of the organism Morphology of the organism The habitat and morphology of the organism

Choose the correct statement amongst the following

Dioecious organisms are seen in both plants and animals

Dioecious organisms are seen only in vertebrates

Dioecious organisms are seen only in plants

Dioecious (hermaphrodite) organisms are seen only in animals
