(b) Mention the changes a flower undergoes after fertilization.
(c ) How does the amount of DNA remain constant though each new generation which is a combination of DNA copies of two individuals?

Text Solution

Verified by Experts

(a) Unisexual Flower - Papaya
Bisexual flower - Hibiscus ( China Rose)
(b) After fertilisation, the fertilized egg divides several times to form an embryo within the ovule. The ovule develops a tough coal around it and is gradually converted into a seed (containing the baby plant along with food). The ovary of flower develops and becomes a fruit (with seeds inside it). The other parts of flower like sepals, petals, stamens, stigma and style dry up and fall off. Only the ovary is left behind.
(c) In sexual gametes, combine together to form a new cell 'zygote' but the amount fo DNA in zygote does not get doubled. This is because the gametes are special type of cell which contain only half of the amount of DNA as compared to the normal body cell of an organism. So the new cell zygote formed by two gametes cell will have the normal amount of DNA.

Study the following information carefully and answer the given questions based on it The English alphabet is categorised into five groups, each starting with a vowel and encompassing the immediately following consonants in the group. Thus group one consists of A, B, C and D, group two consists of E, F,G and H, group three consists of 1, J, K, L, M and N, group four consists of O, P, Q,R, S and T, and the remaining letters make group five. These groups are assigned values as 10 for each letter of first group, 20 for each letter of second group, 30 for each letter of third group, 40 for each letter of fourth group, and 50 for each letter of group five. When used to form words, the value of each letter should be added up to compute the value of the word. If the word has letters only from the same group the value of the word would be the value of the sum of letters. However, if the letters in a word are from difierent groups, the value of the first letter of the word and any other letter of that group will be the same as that of its individual letter value of its group, but that of a letter from another group will be 'double’ as much as the value of each letter of its group. If we have to find the value of MANGO, its first letter is M (from third group), among A, N, G and O, N is also from third group. Hence value of M + N = 30 + 30 = 60 Now A, G and O belong to first, second and the fourth group respectively. Hence value of A + G + O = double the value of A + double the value of G + double the value of O = 2*10 + 2*20 + 2* 40 = 140. Hence, total value = 140+600 = 200.which one or two or three of the words denoted by A, B and C correspond to the given value. 270 (A)WORK (B)COPY (C)THIS 1) A and B only 2) B and C only 3) A and C only 5) All the three None of these
