**Step-by-Step Solution:** 1. **Understanding the Seed Structure**: A seed is the mature form of an ovule, which develops after fertilization. It consists of several parts, including the embryo, endosperm, and seed coat. 2. **Identifying the Components**: - **Embryo**: This is formed when the sperm fertilizes the egg cell. The fertilized egg, called a zygote, develops into the embryo. - **Endosperm**: This is the nutritive tissue that provides food for the developing embryo. It is formed from the fertilization of the polar nuclei by sperm. - **Seed Coat**: This is the outer protective layer of the seed, which is derived from the integuments of the ovule. ...

Read the following statements carefully - (A) The lipid component of the plasma membrane mainly consists of phosphoglycerides. (B) Polar molecules can pass through the lipid bilayer of the plasma membrane, therefore they do not require carrier proteins to facilitate their transport. (C ) The secondary wall is capable of growth and it is formed on the outer side of the primary wall.
