2. Cell Parts and Functions Gaiser Life Science

3. Know Is a cell one part or do many parts make up a cell? Explain in complete sentences. Evidence Page 23 ?

4. Types of cells - cells that have no nucleus or specialized organelles - cells that have no nucleus or specialized organelles prokaryote Clarifying ?s Information Page 24 eukaryote - cells that have a nucleus and organelles - cells that have a nucleus and organelles Example: bacteria and blue-green algae Example: plant and animal cells 1. animal Cell Parts and Functions 2. plant3. bacteria

5. Clarifying ?s Information Page 24 Cell Parts and Functions eukaryote - cells that have a nucleus and organelles - cells that have a nucleus and organelles Example: plant and animal cells nucleus (AKA brain) - controls the cells activities (AKA brain) - controls the cells activities nuclear membrane - protects and defines the nucleus - protects and defines the nucleus chromatin - genetic material - genetic material Cell parts – plant & animal nucleolus – makes ribosomes – makes ribosomes cytoplasm – cell substance between nucleus & cell membrane – has consistency of jelly – cell substance between nucleus & cell membrane – has consistency of jelly mitochondria (AKA the powerhouse of the cell) – produces energy (AKA the powerhouse of the cell) – produces energy

6. Clarifying ?s Information Page 25 Cell Parts and Functions endoplasmic reticulum (ER) – an interconnected network of tubules, vessicles, and sacs that produce and transport a variety of cell substances – an interconnected network of tubules, vessicles, and sacs that produce and transport a variety of cell substances ribosomes – produce protein – have the shape of grains of rice – produce protein – have the shape of grains of rice golgi bodies (AKA mailroom) – receives proteins and distributes throughout cell (AKA mailroom) – receives proteins and distributes throughout cell vacuoles (AKA storage tank) – stores food/water until needed (AKA storage tank) – stores food/water until needed lysosomes – breaks down larger pieces of food into smaller ones – breaks down larger pieces of food into smaller ones cell membrane (AKA gate keeper) – lets things in and out of cell (AKA gate keeper) – lets things in and out of cell

7. Clarifying ?s Information Page 25 Summary: Cell Parts and Functions cell membrane cell membrane (AKA gate keeper) – lets things in and out of cell membrane (AKA gate keeper) – lets things in and out of cell Cell parts – plants only chloroplast – captures sun’s energy to produce food (sugar) chloroplast – captures sun’s energy to produce food (sugar) cell wall cell wall – gives the cell rigidity – lets things in and out of cell wall – gives the cell rigidity – lets things in and out of cell Cell parts – bacteria only Has four main components: 1. Cell wall 2. Cell membrane (AKA plasma membrane) 3. ribosomes 4. chromosome
