Cell Organelles
1. All living things are made of cells 2. The cell is the basic structural and functional unit of life. 3. All cells come from pre-existing cells. Cell Theory
Prokaryote vs Eukaryote v.s. Protists
Prokaryotes Simple and small cells Bacteria Cells!!! Unicellular (is a single celled organism)
Prokaryotes No Nucleus Cell Wall Cell Membrane Cytoplasm DNA in one big loop floating around. Ribosomes: For building proteins
OMG SO SMALL These are prokaryote E. coli bacteria on the head of a pin.
Eukaryotes Animal Cells, Plant Cells, and Protists Has a Nucleus Chromosomes (DNA) inside of the nucleus Membrane-bound organelles (Cell Wall Cell Membrane, Cytoplasm, Ribosomes, etc.) Bigger and more complicated than prokaryotes
Cell Membrane Protects the cell and controls what enters and leaves the cell Made of phospholipid (and protein channels) In ALL cells Protein Phospholipid
Cell Wall Located outside of the cell membrane of plant cells and bacterial cells Protects the cell and keeps plant cells from bursting Made of cellulose (carbohydrate)
Nucleus Directs all cellular activities Contains DNA Which type of cells have this again?
Ribosome Site of protein synthesis (place where proteins are made) In ALL cells That looks familiar…what is a polypeptide?
Mitochondria Converts and releases energy for the cell to use Site of Cellular Respiration
Chloroplast Captures solar energy and converts it into usable energy Site of photosynthesis
Gel-like substance that organelles are suspended in. Found in everything. Cytoplasm
