Answer:
Introduction:
In castor, the proliferation of the outer integumentary cells at the micropyle region is an important process that serves several functions. This process is characterized by the rapid division and growth of the outer integumentary cells, leading to the formation of a specialized structure that plays a key role in the plant's reproduction and survival.
Hygroscopic ability:
The proliferation of the outer integumentary cells at the micropyle region does not have hygroscopic ability. Hygroscopic ability refers to the ability of a substance to absorb moisture from the air. While the outer integumentary cells may play a role in the plant's water balance, they do not have hygroscopic properties.
Myrmecophily:
The proliferation of the outer integumentary cells at the micropyle region does attract ants and helps in myrmecophily. Myrmecophily refers to the interaction between plants and ants, where the plants provide food or shelter to the ants in exchange for protection or pollination. The sugary substances produced by the outer integumentary cells attract ants, which can then help protect the plant from herbivores or pollinate the flowers.
Epiblast:
The proliferation of the outer integumentary cells at the micropyle region is not called epiblast. Epiblast refers to the outer layer of cells in the early embryo of animals. In plants, the outer integumentary cells form the outer layer of the ovule, which later develops into the seed coat.
Sugary substance storage:
The proliferation of the outer integumentary cells at the micropyle region does store sugary substances. The outer integumentary cells produce a sugary substance called nectar, which attracts insects and other animals that can help pollinate the flowers or protect the plant from herbivores.
Conclusion:
In conclusion, the proliferation of the outer integumentary cells at the micropyle region in castor serves several important functions, including attracting ants and other insects, producing sugary substances, and forming the outer layer of the ovule. While this process does not have hygroscopic properties, it is essential for the plant's reproduction and survival.
