What is the first stage of the Cell Cycle
G1 (Gap stage 1) Growth Stage 46 chromosomes
Second stage of the Cell Cycle
S (Synthesis) DNA Replicated 92 chromosomes
Third stage of the Cell Cycle
G2 (Gap Stage Two) Organelles replicated inside the cell and the cell is still growing
What is it called when cytoplasm splits creating new cells
Cytokensis
DNA that has yet to be coiled into chromosome form. DNA in this form during interphase
Chromatin
Protein disc that holds homologous chromosomes together
Centroemere
Organelles built of microtubules that move chromosomes within a nucleus during mitosis and meiosis
Centrioles
Identical pairs of chromosomes are present during the stages of mitosis and meiosis.
Sister chromatids
When molecules move from an area of high concentration to low concentration through a cells membrane
Diffusion
When molecules of water move from an area of high concentration one of low concentration through a cells membrane
Osmosis
How do glucose and some ions have to enter the cell?
Faciliated diffusion
Molecules are forced from regions of higher pressure to lower pressure
Filtration
When molecules are too large to enter or exit by normal means and instead have to enter or exit through special carrier protiens
Facilitated diffusion
How do oxygen, carbon dioxide, and steriods enter and exit the cell?
Diffusion
What are the four organic substances?
carbohydrates, proteins, lipids, nucleic acids
What are the 2 main functions of lipids?
provide cell structure and source of ATP production
