passive transport: transport requiring no energy
active transport:
type of transport requiring energy
osmosis: movement of water from high to low concentration
active transport
type of transport requiring energy
co-transport protein
simultaneously moves an ion and another material into the cell
cell cycle (mitosis & meiosis)
mitosis
Cell division in which the nucleus divides into nuclei containing the same number of chromosomes
4 phases
Prophase
Metaphase
Anaphase
Telophase
chromatin
Combination of DNA and its histone proteins in the nucleus.
sister chromatids:
Duplicate copies of DNA attached at a centromere
G1 Phase
first growth stage of interphase in which cell grows and performs its normal functions
S Phase
the portion of interphase during which DNA is replicated.
G2 Phase
The second growth phase, of the cell cycle, Cells prepare to divide and wait for a signal
