Study Guide BIO 108 Exam #3, CCL Cell organelles, Mitosis, Meiosis 1. ATP-what is it used for The energy produce from ATP is use to power: muscle contraction, Active transport, excretion (exocytosis), molecular synthesis Basically, for growth, movement and reproduction 2. Autosomes: a set of one chromosomes. 3. Cell Cycle: G 0 ,G 1 , G 2 , S, M *G 1= GAP (from cell division(M mitosis) DNA synthesis(S)) / proteins / # of organelles Growth S=DNA synthesis/replication.Chromosomes double,each consist of two sister chromatids. *G 2 =S M: A lot of metabolic activity Protein synthesized for cell division.

Mitotic Phase-M - Mitosis-nuclear division - Cytokynesis-cytoiplasmic division leading to 2 daughter cells. 4. Characteristics of all cells: All organism are made up of one unicellular or multicellular cells Cell is the basic unit of life Cells have complex organizations New cells arise from pre existing cells 5. Characteristics of plant cells : A large central vacuole A cell wall composed of cellulose Plastids, cell wall, Large vacuoles. T hree things that animal cell doesn’t have. 6. Chromatin-description, when is it visible? (Cell cycle) Chromatin : untangle DNA

1.Long strands of DNA wrapped around proteins 2. White spotty areas: diffuse masses **** Visible when chromosomes are diffused. ****When the cell divides, the chromatin reorganizes so that the chromosomes become visible. 7. Chromosomes-when are they visible? Chromosomes are visible in their condense state. When the cell divides, the chromatin reorganizes so that the chromosomes become visible. 8. Cilia and flagella: functions, what they are made of Cilia and flagella are both extension of the cytoplasm Flagella : 1 or few ( sperm are flagelatted ) undulating motion Cilia: shorter , more numerous , propel cell , move around protist , move debris and mucus past their cells 9. Cytoplasmic streaming Intracellular motility Movement of the cytoplasm 10.Density dependent inhibition and cancer cells Cancer cell do not exihibit density dependent inhibition.

11.Diploid cells 2n , the number of chromosome 12. DNA replication-when? DNA Replication occurs prior to Meiosis In both mitosis and meiosis DNA replication occurs during interphase before cell division. 13. Endosymbiont theory : A small prokaryote came to live symbiotically inside larger prokaryote which eventually evolved into a eukaryote. The prokaryote evolved into mitochondrion. 14.Fate of vesicles that emerge from E.R.
