DF LEP Bio Cell Proc
DF LEP Bio Cell Processes
| Question | Answer |
|---|---|
| mitosis | division of the nucleus in body cells |
| meiosis | division of the nucleus in sex cells |
| cytokinesis | the process of dividing the cytoplasm to form 2 cells (happens during telophase) |
| the 4 stages of mitosis | prophase metaphase anaphase telophase |
| interphase | a time of growth, function & preparation for mitosis |
| replication | the copying of genetic material |
| sister chromatids | the chromosome & it's copy, attached by a centromere |
| daughter cells | the 2 cells resulting from mitosis, exactly like each other & the original |
| spindle fibers | used as a guide for chromosomes to move along during mitosis |
| chromatin | threadlike genetic material found in nucleus |
| sex cell AKA gamete | sperm or egg cell |
| cellular respiration | produces energy when food molecules are broken down |
| photosynthesis | process in which producers change light energy into chemical energy |
| metabolism | the total of all chemical activities of an organism |
| endocytosis | a method in which cells can bring a large molecule into the cell |
| passive transport | uses no energy, includes diffusion & osmosis |
| osmosis | the transport of water molecules across the cell membrane |
| diploid cell | contains chromosomes found in homologous pairs |
| carbon dioxide | an end product of respiration, a raw material of photosynthesis |
| oxygen | an end product of photosynthesis, a raw material of respiration |
| active transport | transport requiring energy |
| diffusion | movement of molecules from an area of high concentration to an area of lesser concentration |
