B3201 - U1 Chap12 Test #3

1. nucleus, creates the pollen tube
4. the female reproductive organ in flowering plants
5. the cell formed from the joining of the sperm nucleus and the egg nucleus
7. haploid generation of a plant that produces male and female gametes that fuse at fertilization to form a diploid sporophyte
8. fertilization, process where one sperm fertilizes an egg and another sperm fuses with two polar nuclei
10. type of virus lifecycle where the virus actively invades and destroys host cells
12. the structure that forms from an ovule
14. diploid generation of a plant that produces haploid spores that develop without fertilization into a gametophyte
16. a sac that contains female gametes
18. part of the stamen that contains cells that undergo meiosis and mitosis to form pollen grains
21. a cell with two pairs of homologous chromosomes
23. part of the pistil that contains one or more ovules
24. the male reproductive organ in flowering plants

1. the type of cell formed when the sperm nucleus and the two polar nuclei join together
2. type of virus lifecycle where the virus uses a host to replicate its DNA but doesn't immediately destroy the host cell
3. nuclei, the two nuclei inside one of the 8 cells produced from the megaspore
6. part of the pistil that is located at the tip of the pistil and is the place where pollination takes place
9. the haploid female gametophyte that will undergo mitosis to produce 8 haploid cells within the embryo sac
11. nucleus, creates two sperm cells after undergoing mitosis
12. part of the pistil that connects the stigma to the ovary
13. the structure that forms from an ovary
15. a grain that contains two haploid cells
17. a cell with half the number of chromosomes as a diploid cell
19. part of the stamen that supports the anther
20. produced from specialized cells in the anther that undergo meiosis, will undergo mitosis to form a tube cell/nucleus and a generative cell/nucleus
22. the food supply for the plant embryo
