- scutellum
- perisperm
- tapetum
- coleoptile
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The albuminous seeds retain a part of endosperm as it is not completely used up during embryo development, e. g., wheat, maize barley, etc., However, in some seeds such as black pepper and beet, remnants of nucellus are also persistent.
This residual persistent nucellus is called perisperm.
This residual persistent nucellus is called perisperm.

Sexual Reproduction in Flowering Plants
Sexual reproduction in flowering plants takes place or happens when the production of a new organism occurs from two parents by making use of their gametes or sex cells. Both sexual and asexual reproduction can be found in plants. Nearly all flowering plants reproduce sexually. Flowers play a captious role in the process as it carries both the male and female reproductive parts commonly known as androecium and gynoecium respectively.
An individual flower comprises the following parts -
- Pedicle
- Calyx
- Petals
- Sepals
- Stamen
- Pistil
- Receptacle
