Cell Parts and Functions Gaiser Life Science Know Is a cell one part or do many parts make up a cell? Explain in complete sentences. Evidence ? Page 23 Clarifying ?s Cell Parts and Functions Information Types of cells 1. animal 2. plant 3. bacteria prokaryote - cells that have no nucleus or specialized organelles Example: bacteria and blue-green algae eukaryote - cells that have a nucleus and organelles Example: plant and animal cells Page 24 Clarifying ?s eukaryote Cell parts – plant & animal Cell Parts and Functions Information - cells that have a nucleus and organelles Example: plant and animal cells nucleus (AKA brain) - controls the cells activities nuclear membrane - protects and defines the nucleus chromatin - genetic material nucleolus – makes ribosomes cytoplasm mitochondria – cell substance between nucleus & cell membrane – has consistency of jelly (AKA the powerhouse of the cell) – produces energy Page 24 Clarifying ?s Cell Parts and Functions Information endoplasmic reticulum (ER) – 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 vacuoles (AKA mailroom) – receives proteins and distributes throughout cell (AKA storage tank) – stores food/water until needed lysosomes – breaks down larger pieces of food into smaller ones cell membrane (AKA gate keeper) – lets things in and out of cell golgi bodies Page 25 Clarifying ?s cell membrane Cell Parts and Functions Information cell membrane (AKA gate keeper) – lets things in and out of cell Cell parts – plants only chloroplast chloroplast – captures sun’s energy to produce food (sugar) cell wall 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 Summary: Page 25 This PowerPoint was created from Charlene Shea’s lecture notes by Tim Paterek.
