FAQs on Female Gametophyte: Carpel Video Lecture - NEET

1. What is a carpel in the female gametophyte?
Ans. A carpel is the female reproductive structure found in the flower of angiosperms. It consists of three main parts: the stigma, style, and ovary. The carpel plays a crucial role in the production of female gametes and the fertilization process.
2. How does the carpel contribute to the development of the female gametophyte?
Ans. The carpel contains the ovary, which houses the ovules. The ovules are responsible for the production of female gametophytes, also known as embryo sacs. Within the ovule, the female gametophyte undergoes development and maturation, eventually leading to the production of eggs for fertilization.
3. What is the function of the stigma in the carpel?
Ans. The stigma is the receptive surface of the carpel, and its main function is to receive pollen grains during pollination. It is often sticky or covered in hairs to facilitate pollen adhesion. The stigma plays a crucial role in the fertilization process by capturing and recognizing compatible pollen for successful reproduction.
4. How does the style assist in the fertilization process?
Ans. The style is the elongated part of the carpel that connects the stigma to the ovary. Its primary function is to provide a pathway for the pollen tubes to grow and reach the ovules. After pollen grains land on the stigma, they germinate and develop pollen tubes that travel through the style to deliver sperm cells to the ovules for fertilization.
5. What role does the ovary play in the female gametophyte?
Ans. The ovary is the enlarged basal part of the carpel, and it contains one or more ovules. The ovary protects the developing ovules and provides them with nutrients and support. It also plays a crucial role in the formation of seeds after fertilization occurs. The ovary develops into a fruit, which aids in seed dispersal.
