Write the modes of asexual reproduction in the following organisms.
Bryophyllum, Potato, Yeast, Rhizopus, Penicillium.

Which is better mode of reproduction, sexual or asexual?Why?

Read the following statements and find out the incorrect statements. a. Asexual reproduction is common among single celled organisms, and in plants and animals with relatively complex organisations. b. In yeast, the division is unequal and small buds are produced that remain attached initially to the parent cell which eventually gets separated and mature into new yeast organism (cells). c. Vegetative reproduction is also a type of asexual reproduction. d. While in animals and other simple organisms the term vegetative reproduction is used unambiguously, in plants, the term asexual reproduction is frequently used. e. Water hyacinth is also called 'Terror of Bengal.'

Read the following statements carefully and select the appropriate option given below. (i) Reproduction is defined as a biological process in which an organism gives rise to the young ones (offspring) similar to itself. (ii) Adventitious buds arise from the notches present at margins of leaves of Bryophyllum. (iii) Asexual reproduction is common among single celled organisms, and in plants and animals with relatively simple organisations. (iv) A few plants exhibit unusual flowering phenomenon, some of them such as bamboo species flower only once in their life time, generally after 50-100 years. (v) The events of asexual reproduction though elaborate and complex, follow a regular sequence.

Write the structures of the following organic compounds. 2,5, 6- Trimethyloctane. Hexane - 2, 4 - dione. 5 - Oxohexanoic acid.

Read the following statements carefully and select the appropriate option given below. (i) Bisexual animals that possess both male and female reproductive organs, are hermaphrodites. (ii) In seed plants, pollen grains are the carriers of male gametes and ovule have the egg. (iii) Events in sexual reproduction before the formation of zygote are called post-fertilisation events. (iv) Sexual reproduction involves the formation and fusion of gametes, (v) Animals are categorised into oviparous and viviparous based on whether the development of the zygote takes place outside the body of the female parent or inside.

In asexual reproduction, offsprings are produced by a single parent with or without the involvement of gamete formation. Name the asexual reproductive structures a and b given below. (a ) hydra (b ) penicillium

Although sexual reproduction is a long drawn, energy intensive complex form of reproduction, many groups of organisms in kingdom Animalia and plantae prefer this mode of reproduction. The reason for this is
