Rafflesia arnnoldi is a species of flowering plant in the parasitic genus Rafflesia. It is noted for producing the largest individual flower on earth. It has a very strong and horrible odour of decaying flesh, earning it the nickname "corpse flower"

The male gametophyte in angiosperm is reduced to
1 one cell
2 two cells
3 three cells
4 four cells
Explanation:
In pinus the male gametophyte is much smaller than the female gametophyte. It is made up of three cells. The male gametophytes of angiosperms is composed of one tube cell and one generative cell. This generative cell divides to form two male gametes. So, the angiospermic male gametophyte is 3 -celled.

Double fertilization is a characteristic of:
1 angiosperms
2 gymnosperms
3 thallophytes
4 all plants
Explanation:
- Double fertilization is a characteristic of angiosperm. It was first discovered by S.G. Nawaschin (1898). Double fertilization where a triploid endosperm is formed as a result of the fusion of secondary polar nuclei a male gamete. A diploid zygote is formed by the fusion of a haploid egg cell and a haploid male gamete.

Double fertilization (or triple fusion) leading to initiation of endosperm in angiosperms, requires
1 fusion of 4 or more polar nuclei and the second male gamete only
2 fusion of 2 polar nuclei and second male gamete only
3 fusion of one polar nucleus and second male gamete only
4 all the above type of fusions in different types of angiosperms
Explanation:
Double fertilization (or triple fusion) leading to initiation of endosperm in angiosperms, requires fusion of Two polar nucleus and second male gamete only.
