Question

Are integuments haploid or diploid?

Answer 1

Haploid cell

1. A haploid is a type of cell that has only one set of chromosomes (n).
2. Gametes are an example of haploid cells.

Diploid cell

1. The cells that have two sets of chromosomes (2n) are called diploids.
2. Zygotes, plant cells, and animal cells are some examples of diploid cells.

Integuments

1. Integuments in plants are one or two layers of protective covering surrounding the ovule.
2. They have a small opening through which the pollen enters the ovule called a micropyle.
3. Their main function is to protect the ovule in the nucellus and after fertilization, it converts into a seed coat.
4. The outer integuments develop into thick testa and inner into thin tegmen during embryonic growth.
5. Integuments are diploid in angiosperms as well as in gymnosperms.
