Cells and Cell Division by Mind Map: Cells and Cell Division

1. Cell Structure and function

1.1. Plasma Membrane

1.1.1. Controls movement of molecules

1.1.2. Molecules give cell molecular identity, genetically determined, responsible for important cell properties.

1.1.3. Encloses Cytoplasm

1.2. Cytoplasm

1.2.1. Water with proteins, salts and sugars

1.2.2. Cytoskeleton=Microtubules and microfilaments shaping and supporting to cell

1.2.3. Contains organelles

1.3. Organelles (little organs)

1.3.1. Endoplasmic Reticulum: Smooth in lipid synthesis rough involved in protien synthesis

1.3.2. Golgi Complex: Sorts, chemically modifies and packages protiens from rough ER

1.3.3. Lysosome: digests materials

1.3.4. Mitochondrion: gives cell fuel through breakdown of glucose to make ATP

1.3.5. Nucleus: contains genetic info that controlls cell structure and function

1.3.6. Nucleolus: where RNA for protien synthesis is made

2. Cell Cycle

2.1. Interphase

2.1.1. Grow and carry out life functions for survival

2.1.2. Non-Reproductive Stage

2.1.3. May stay in interphase for individuals life span

2.2. Mitosis

2.2.1. cells are Reproducing

2.2.2. external signals trigger

2.2.3. preperation for mitosis begins during Interphase where chromosomes duplicate

2.2.4. Goal is to sort chromosomes into 2 identical sets

2.3. Cytokinesis

2.3.1. cytoplsm and cell membrane divide up between two nuclei

2.3.2. cells return to interphase

2.4. Significance of mitosis and Cytokinesis

2.4.1. Increases Cell Number

2.4.2. Makes replacement cells

2.4.3. Cancer results when cell reproduction is out of control

3. New node
