Answers to the questions of last week:
1. What is meant Dy vogtuaVAN propagation in the flowering plants? Explain briefly four advantages of vegetative propagat- ion.
Ans. In some cases, flowering
of their plants can reproduce more: own kind without the use of: gametes produced in the sex organs of flowers, but from stems, roots. or leaves. Since these are the vegetative parts of the plant normally used for nutrition, sc this way of reproduction in plante is known as vegetative propagation It is similar to the process of regeneration in certain animals Four advantages of vegetative propagation are stated as Follows:-
(1) The new offspring are exactly alike the parent plants, from which thry are detached off, iL colour, shape and size. This advantage is favourable to the growth of the new plants. (2) The new plants depend on. their own activity to grow, so there is no need to depend on the. processes of pollination and dis- persal of seeds by agents such as wind
, insects, water and animals. (3) The period of time needed for the growth and development of the new plants is short as food and buds are present already.
(4) By vegetative reproductión, the same species of new offspring. can be propagated and increased more in quantity.
2. Describe, with the aid or diagrams, the external features. of (a) a bulb, (b) a rhizome, and (c) a corm, and show how these structures may bring about veget- ative reproduction?
ins. (a) A bulb-----e.g. Union
A bulb is the underground enuut containing a dish-like ster from which fleshy thick and whitish leaves embedded. From the base of the dish-like stem advent- itious roots are developed. During reproduction the terminal bud - develops into the aerial shoot while the exillary bud finally becomes daughter bud for the growth of the next season,

Adventitious roots
(b) A rhizome
-e.g. Ginger
A rhizome is a swollen,, hori
zontal and under-ground stem bear-
ing prominent terminal buds, axillary buds,, scale leaves and adventitious roots, he stored
food is evenly distributed through -out the stem.
The aerial shoots die every year and in the following year growth is carried on by one more lateral buds. It continues to grow year after year in this condition.

A corm is a roughly

and vertical undergrou bears all the parts found in a. rhizome. Usually a corm grows deep in the soil, and
and possesses axillary buds, adventitious and contractile roots. Ex the corm is enclosed by brown colour scale-leaves.
In spring the growth of th buds forms aerial shoots; the terminal buds bear leaves and flowers while the lateral buds bear only leaves. A new corm le developed at the base of the aerial shoot.

Questions for This week
1. What is meant by pollination in flowers? Explain briefly the types of pollination? How does a wind-pollinated flower differ from an insect-pollinated flower. 2. Describe, with the help of a Labelled diagram, the struc of a neamed Insect-pollinated flower, and state the function of the various parts of the flower. What changes, would occur in the Parts of the flower after fertili zation?
