The nucellar tissue is either absorbed completely by developing embryo sac and embryo or small portion may remain as storage tissue. Perisperm is distinct from endosperm, which is another nutritive tissues found in the seed of may angiosperm such as Black pepper, Beetroot and coffee etc. The seed have perisperm is called perispermic seed.

Mention the ploidy of parthenogenetic embryo, parthenocarpic fruit and apomictic seeds in series
1 \(n 2 n 2 n\)
2 \(2 \mathrm{n} n 2 \mathrm{n}\)
3 \(\mathrm{n} 2 \mathrm{n} n\)
4 \(2 \mathrm{n} n \mathrm{n}\)
Explanation:
The ploidy of parthenogenetic embryo, parthenocarpic fruit and apomictic seeds are \(2 n, n\) and \(2 \mathrm{n}\) respectively.

Coconut water from a tender coconut is :
1 Degenerated nucellus
2 Immature embryo
3 Free nuclear endosperm
4 Innermost layers of the seed coat
Explanation:
Coconut water is often referred to as "coconut liquid endosperm' the endosperm is a nutrient - rich tissue inside the coconut seed, and in the case of the coconut, it is largely liquid when the coconut is young. Coconut seed matures the liquid endosperm gradually solidified into white flesh or meat of the coconut. It contains water, sugars, vitamins, minerals and electrolytes, making it a popular natural drink in tropical regions and a great source of hydration.

Micropyle of seed is involved in the passage of
1 Male gametophyte
2 Pollen tube
3 Water
4 Gases
Explanation:
A micropyle is a small or narrow formed by the bulge of the pores during which the pollen enters to the egg cell. In the seeds, there is a micropyle through which the water pierces the seeds in the germination.
