Cell growth and division : - Coggle Diagram
Cell growth and division :
chromosomes - tread like structures found in the nucleus they occur in pairs - homologous pairs - usually formed after cells divide
46 chromosomes in humans
Gene: is a section of chromosome coding e.g eye color , blood type
cells in our body - have an exact copy of all the gene's
Cytokinesis - Division of cytoplasm
animal cells separate to form daughter cells
cell divison - spilting of cell
Meiosis - division of sex cells
Mitosis - divison of stomatic cells
Diploid - has sets of chromosome's
Haploid - unpaired chromosomes
Cells that divide - skin cells and embroys
Passed on cells - germ cell - future generation shall have gene's present -
Stomatic cells - aren't passed on
Devlopment of cells - cell cycle
Mitosis - process - interphase - DNA is copied ready for cell division - centrosomes microtubes attach
Metaphase - chromosomes line up against cell equator - centroiles extend fibres from mitotic spindle then attach to the chromatids
Ana phase - centromere's divide - chromatids separate by spindle and are pulled to opposite poles .
Telophase - chromosomes at poles - membranes formed around each nucleus divides -
