Rahul Pillai answered |
The correct answer is option 'A' - Placenta.
The region within the ovary where one or more ovules are attached is called the placenta. The placenta is an essential structure in the reproductive system of flowering plants. It plays a crucial role in the development and maturation of the ovule.
Here is a detailed explanation of the answer:
1. What is the placenta?
The placenta is a specialized structure found in the ovaries of flowering plants. It is formed by the fusion of the base of the ovary with the funicle, a stalk-like structure that connects the ovule to the ovary wall. The placenta provides the necessary nutrients and support for the developing ovules.
2. Structure of the placenta:
The placenta consists of several components:
- Placental tissue: This is the region within the ovary where the ovules are attached. It contains specialized cells that facilitate the exchange of nutrients and gases between the developing ovules and the surrounding tissues.
- Funicle: The funicle is a stalk-like structure that connects the ovule to the placental tissue. It contains vascular tissues that transport nutrients and water to the ovule.
- Ovule: The ovule is the reproductive structure within the placental tissue. It consists of the embryo sac, which contains the female gametes, and protective coverings such as integuments.
3. Functions of the placenta:
The placenta performs several important functions during the development of the ovule:
- Nutrient supply: The placental tissue provides essential nutrients, such as sugars, amino acids, and minerals, to the developing ovules. These nutrients are transported through the vascular tissues of the funicle.
- Gas exchange: The placenta facilitates the exchange of gases, such as oxygen and carbon dioxide, between the developing ovules and the surrounding tissues. This exchange is crucial for the metabolic processes and respiration of the ovules.
- Waste removal: The placenta also helps in the removal of metabolic wastes produced during the development of the ovules. These waste products are transported away from the ovules through the vascular tissues of the funicle.
- Support and protection: The placenta provides mechanical support and protection to the developing ovules. It acts as a barrier against physical damage and pathogens, ensuring the successful development and maturation of the ovules.
In conclusion, the region within the ovary where one or more ovules are attached is called the placenta. It is a specialized structure that plays a crucial role in the development and maturation of the ovules by providing nutrients, facilitating gas exchange, and offering support and protection.
