Unformatted text preview: iosperm is the sporophyte. 3. Know diagram of flower 4. Know diagram of male and female gametophytes 5. The cell types present in the mature pollen grain are the generative cell and then tube cell. male mature pollen grain contains generative and tube cell 6. A pollen tube is a tube formed after germination of the pollen grain that function in the delivery of sperm to the ovule; develops from the tube cell. pollen tube function is delivery of sperm to ovule 7. The process responsible for converting the microsporocyte to a microspore is meiosis. microsporocyte to a microspore happens from MEIOSIS 8. The primary difference between a microsporocyte and a microspore is that microsporocytes are diploid (2n) while microspores are haploid (n). microsporocytes are DIPLOID and microspores are HAPLOID 9. The process responsible for converting the megasporocyte to a megaspore is meiosis. megasporocyte to a megaspore happens from MEIOSIS 10. The primary difference between a megasporocyte and a megaspore is that megasporocytes are diploid (2n) and megaspores are haploid (n). megasporocytes are DIPLOID and megaspores are HAPLOID 11. Three mitotic divisions are required for conversion of the megaspore to the female gametophyte . three mitotic divisions convert the megaspore to the female gametophyte 12. One mitotic division is required to convert the microspore to the male gametophyte. one mitotic division converts the microspore to the male gametophyte 13. What are the functions of… G enerative ce ll - divides and produces 2 sperm cells which remain inside the tube cell T ube cell - produces the pollen tube E gg cell A padal cells - function unknown P olar cells - combine with sperm to give rise to endosperm S ynergids - help attract and guide pollen tube to the embryo sac 14. Double fertilization is the union of two sperm cells with different nuclei of the female gametophyte. This ensures the endosperm will develop only in ovules where the egg has been fertilized. double fertilization ensures endosperm will develop only in ovules where egg is fertilized 15. The part of...
