Castor seed with endosperm, perisperm, and caruncle
The correct answer to the question is option 'c', which is Castor. Castor seeds are a unique example of seeds that possess endosperm, perisperm, and caruncle.

Endosperm
Endosperm is a nutrient-rich tissue found within the seeds of flowering plants. It serves as a source of energy and nutrition for the developing plant embryo. In Castor seeds, the endosperm plays a crucial role in providing the necessary nutrients for the germination and growth of the plant.

Perisperm
Perisperm is another type of nutritive tissue that surrounds the embryo in certain seeds. It is derived from the nucellus or integuments of the ovule. In Castor seeds, perisperm functions to store reserve food materials that are essential for the early stages of seed germination and seedling development.

Caruncle
A caruncle is a specialized structure found in some seeds that serves as an additional source of nutrients and aids in seed dispersal. It is often located at the micropylar end of the seed and can vary in size and shape. In Castor seeds, the caruncle helps in the absorption of water and nutrients during germination, contributing to the successful establishment of the plant.
In conclusion, Castor seeds are a prime example of seeds that possess endosperm, perisperm, and caruncle, highlighting the diverse and specialized structures present in different plant seeds.
