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

1.The habitat and morphology of the organism

2.Morphology of the organism

3.Morphology and physiology of the organism

4.The organism’s habitat, physiology and genetic makeup

Vegetative propagule in Agave is:

Examine the figure (A-D) given below and select the right option out of 1-4, in which all the four structures A, B, C, and D are identified correctly:

Options

A haploid parent produces gametes by: 

(1) mitosis 

(2) meiosis 

(3) endomitosis 

(4) amitosis 

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

1. Haploid vegetative cells and diploid gametangia

2. Diploid vegetative cells and diploid gametangia

3. Diploid vegetative cells and haploid gametangia

4. Haploid vegetative cells and haploid gametangia

Encystation in unfavourable conditions followed by multiple fission and sporulation when the favourable conditions return is seen in:
1. Sponges
2. Penicillium
3. Amoeba
4. Yeast

Which of the following plants is monoecious? 

1. Marchantia polymorpha

2. Cycas circinalis

3. Carica papaya

4. Chara

Offspring formed by sexual reproduction exhibit more variation than those formed by asexual reproduction because:

1.Sexual reproduction is a lengthy process

2.Gametes of parents have qualitatively different genetic composition

3.Genetic material comes from parents of two different species

4.Greater amount of DNA is involved in sexual reproduction.
