3 components of cell theory |
1.all living organisms are composed of one or more cells 2.cells are the basic unit of structure and organization of all living things 3.cells arise only from other cells |
|
|
What are organelles? |
Specialized internal cell structures that carry out protein synthesis and energy transformation |
|
|
Define Nucleus |
Center of an atom, made up of neutrons and protons. |
|
|
Eukaryotic Cells |
Plant & Animal Cells Contain: Cell Wall(cellulose), chloroplasts, vacuoles,ER, Nucleus, Golgi Apparatus, Mitochondria, Cell Membrane, Cytoskeleton, DNA, ribosomes |
|
|
Prokaryotic Cells |
Bacteria Cells Contains: Cell Wall(Pepdidoglycan), Cell Membrane, Cytoskeleton, DNA, Ribosomes |
|
|
Plasma Membrane |
Flexible, selectively permeable boundary that helps control what enters and leaves the cell |
|
|
Selectively Permeable |
Membrane allows some substances to pass through while keeping others out |
|
|
Fluid Mosaic Model |
Phospholipids create "sea" where molecules float. Different substances a pattern(mosaic) is created on surface |
|
|
Transport Proteins |
Proteins that create tunnels through which certain substances enter and leave the cell |
|
|
Major differences between plant & animal cells |
Animal- have centrioles and lysosomes Plant- have cell wall(cellulose) and chloroplasts |
|
|
Ribosomes |
Help manufacture proteins |
|
|
Rough/Smooth ER |
Folding membrane system in eukaryotic cells that is the site for all protein and lipid synthesis |
|
|
Golgi Apparatus |
Flattened stack of tubular membranes that modifies proteins |
|
|
Vacuoles |
Membrane bound vesicle for temporary storage of food, enzymes and waste |
|
|
Lysosomes |
Uses enzymes to digest excess or worn-out cellular substances |
|
|
Centrioles |
Plays a role in cell division and is made of microtubules |
|
|
Mitochondria |
Converts fuel into energy that is available to rest of cell |
|
|
Chloroplast |
Double membrane organelle that captures light energy & converts to energy through photosynthesis |
|
|
Cell Wall |
Surrounds outside of plasma membrane, protects cell |
|
|
Cilia |
Move cell itself. Move substances past cells |
|
|
Flagella |
Help in cell movement |
