Vegetative propagation is common among angiosperm Runner produces adventitious roots from the nodes and grow. Among lower plant groups a type exhibit that pattern of growth. (a) Identify the plant and its growth (b) What are the speciality of leaves in that group?

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.

Plants living in swamps from which some special roots arise vertically upwards and come out the soil. a. What is the special roots? b. What is its function?

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.'

In some lower and higher plants offspring are produced shows greater similarity and it occurs mainly through asexual reproduction,in higher plants the process ocuurs through vegetative propagation. a) What is vegetative propagation? b) Give two suitable examples.

Among the following, select the correct statements. (a) In majority of higher plants and animals, growth and reproduction are mutually exclusive events. (b) In non-living objects growth is byaccumulation of material on the surface. (c) An isolated metabolic reaction outside the body of an organism, performed in a test tube is neither living nor non-living. (d) All organisms, from the prokaryotes to the most complex eukaryotes can sense and respond to environmental cues.
