Each carpel of Gloriosa encloses 60 ovules, out of which \(27 \%\) became abortive and another \(13 \%\) could not be fertilized due to various reasons. How many seeds occur in the capsule if all the remaining ovules are fertilized in the lone flower of the plant?
1 36
2 76
3 108
4 180
Explanation:
: Ovules in the ovary become seeds when the ovary is developing into a fruit. Since Number of fertilized ovule will be equal to number of seeds produced Gynoecium of Gloriosa contains 3 carpels, number of ovules in each carpel is given \(=60\) Therefore, number of ovules in 3 carpels \(=60 \times 3=180\) abortive ovules \(=27 \%\) unfertilized ovules \(=13 \%\) Therefore, total number of fertilized ovules \(=100-(27\) \(-13)=60\) So, No of seeds in a cone flowers of Gloriosa \(=60 \%\) of \(180=\frac{60 \times 180}{100}=108\)

Explanation:
A Funiculus:- The stalk by which on ovule or seed is connected to the placenta in the ovary. Funiculus after seed formation develope into the stalk of seed. Scar of ovule:- The body of the ovule fused with the funicle in the region called hilum. The hilum is the scar that is present on the seed Zygote:- The fertilized egg is called zygote. The two celled zygotic stage till the initiation of organs in embryo is commonly called proembryo stage Inner Integument:- Ovule has one or two protective envelope called integuments. The inner integument forms the tegmen

Parachute mechanism of seed dispersal is seen in:
1 Poppy
2 Helianthus
3 Plumbago
4 Lotus
Explanation:
B Parachute mechanism:- some seeds are light and float in the wind. These seeds land and grow in new places. It is a characteristic of family compositae (Asteraceae family), e.g. Helianthus (sunflower).
