cell divison Flashcards
basic function of the nucleus
contains dna information of a cell
basic function of the endoplasmic reticulum
a network of tubes for transport of molecules
basic function of the mitochondria
makes energy using glucose and oxygen
basic function of the golgi bodies
removing waste
list 3 organelles that are unique to plant cells. what are the basic functions?
cell wall: provides strength and protection
chloroplast: produces energy through photosynthesis
vacuole: stores water and nutrients
list the three main reasons why cell division is important
reproduction, repair, and growth
interphase
strands start to duplicate
prophase
nuclear membrane breaks down and chromosomes become visible
metaphase
the chromosomes line up in the middle
anaphase
sister chromatids become daughter chromosomes, they move to opposite sides, the centerom splits
telophase
daughter chromosomes are no longer visible, new nuclear membrane is formed
cytokinesis
cytoplasm divides
what is cytokinesis, how is it different for plant and animal cells ?
plant: daughter cells dived into a new cell plate
animal: the cell membrane is pinched into a new cell
what is typically the longest phase of the cell cycle?
interphase
