Male gametes in angiosperms are formed by the division of
1 Microspore
2 Generative cell
3 Vegetative cell
4 Microspore mother cell
Explanation:
Male gametes in angiosperms are formed by the division of generative cell. It is formed during the microspore's first division and divides into two sperm cells in the pollen grain or pollen tube. As a result, the generative cell is never "Free" from the vegetative cell.

Which of the following is a total root parasite?
1 Cuscuta
2 Rafflesia
3 Santalum
4 Monotrapa
Explanation:
Rafflesia arnoldii is a species of flowering plant which belongs to the parasitic genus Rafflesia. It is the most famous species as it produces the biggest individual flower on earth and is also known as the corpse lily or stinking corpse lily. They lack in chlorophyll and does not prepare their own food. They take their food along with water and minerals from the roots of the host plant and depend on the host, such plant is known as a total root parasite.
Velamen tissue is found in epiphytes. Such as in orchids and clivia species aerial roots. It is a multilayered tissue that is spongy in nature which covers the aerial roots of epiphytic plants such as Orchids. It helps in the absorption of water.
