Study Notes
Fertilization Process
- Fusion of one sperm nucleus with the egg cell is called syngamy.
- Fusion of the remaining sperm with the secondary nucleus is termed double fertilization.
Gametophytes and Egg Cells
- The mature female gametophyte in flowering plants is known as the embryo sac.
- Generally, there is one egg cell present in the embryo sac.
Role of Synergids
- Synergids serve as guides for pollen tube growth toward the egg cell, facilitating fertilization.
Polar Nuclei Fusion
- The nucleus formed from the fusion of the polar nuclei is referred to as the triploid nucleus.
Pollination
- The transfer of pollen grains from anthers to stigma is called pollination.
- Self-pollination and cross-pollination are the two types of pollination.
Types of Pollination
- Self-pollination involves the transfer of pollen within the same flower.
- Cross-pollination involves the transfer of pollen from one flower to another.
Apomixis in Plant Breeding
- Recurrent forms of apomixis are beneficial for plant breeding as they allow for the combination of desirable traits without sexual reproduction.
Confirmation of Apomictic Nature
- The nature of apomictic plants can be confirmed through genetic analysis or evaluating seed formation without fertilization.
Endosperm Function
- The primary function of the endosperm in flowering plants is to provide nutritional support to the developing embryo.
Asexual Reproduction
- Asexual reproduction in plants involves the formation of new individuals from a single parent plant without fertilization.
Types of Asexual Reproduction
- The two types of asexual reproduction are vegetative reproduction and asexual seed formation.
Categories of Vegetative Reproduction
- Vegetative reproduction can be categorized into natural and artificial methods.
Types of Underground Stems
- Four types of underground stems include rhizomes, tubers, bulbs, and corms.
Example of Rhizome Reproduction
- An example of a plant that reproduces through rhizomes is bamboo.
