| Term | Definition |
|---|---|
| hyphae | single filaments of fungus |
| mycelium | vegetative part of a fungus, consisting of a mass of branching, thread-like hyphae. |
| Plasmogamy | cytoplasm of two parent cells fuse together |
| karyogamy | fusion of two nuclei |
| phaeophyta | brown algae |
| cell cycle | a series of events that takes place in a cell as it grows and divides. |
| stem cells | simple cell in the body that is able to develop into any one of various kinds of cells. |
| differentiation | development from the one to the many, the simple to the complex, or the homogeneous to the heterogeneous. |
| totipotency | The ability of cells such as an embryonic stem cell to differentiate into any type of body cell. |
| interphase | first step of mitosis- when cells are actually doing things, everything BUT division. |
| M phase | division |
| nuclear division | duplicated chromosomes separate to form two genetically identical daughter nuclei. |
| Cytokinesis | cytoplasm of a cell is physically divided to form two daughter cells housing the newly formed nuclei. |
| G1 phase | this is where growth happens, some cells stop and differentiate while some will die. |
| S phase | SYNTHESIS- DNA replication/copying |
| endoreplication | cells undergo interphase but do not divide |
| chromatin | mass of genetic material composed of DNA and proteins that condense to form chromosomes. |
| What is produced by mitosis? | 2 daughter cells |
| gametes | sex cell (sperm and eggs) |
| zygote | a cell formed when 2 gamete cells are joined by occurrence of sexual reproduction. |
| haploid | cell has only one set of chromosomes |
| diploid | 2 complete sets of chromosomes, 1 from each parent. |
| Syngamy | joins haploid(gametes) cells to form new unique diploid(zygote) cell. |
| gametophyte | haploid stage of a plant. produces HAPLOID gametes |
| mushrooms | basidiomycota |
