Cell Membrane:
- The outer border of a cell
- Controls what gets in and out of the cell
- Made of lipids and proteins
Nucleus:
- Largest organelle (animal) cell
- Holds DNA (Instructions to build organisms)
Organelle (Small Fat Bubble):
- Small Membrane-bound compartments inside a cell
Nuclear Membrane:
Nuclear Pore:
- Control what gets in and out of the nucleus
Nucleolus:
Prokaryotes:
- Do not have a nucleus
- Very primitive
Eukaryotes:
- Cells with a nucleus and other organelles
- More advanced
Endoplasmic Reticulum:
- Pathway for proteins and RNA inside the cytoplasm
Cytoplasm:
- gel-like substance
- made of water + protein
Ribosomes:
Golgi Apparatus:
- Series of flattened membrane discs
Steps of making a protein:
- RNA leaves the nucleus and floats down RER until it hits a ribosome
- The ribosome reads directions on the RNA and connects proper amino acids to build the protein
- Protein slides down ER to end
- Part of the ER pinches off to form a transport vessel that merges into Golgi to repeat → until protein reaches its final destination
Mitochondria:
- Powerhouse of the cell
- Site of aerobic respiration (glucose →ATP)
Coristae:
- Highly folded membrane inside mitochondria where aerobic respiration takes place
Lysosome:
- Filled with acid & enzymes to digest recycle worn-out cell plants
Vacuole:
- Storage compartment in cell for extra stuff ( water, colored pigments)
- Largest vacuole in plants
- Hundreds of smaller vacuoles in animals
Cytoskeleton:
- A network of fine fibers in a cell that provide support
Plant Cells:
- Rectangle
- Brick
- Cell Wall
- Support, made of cellulose
- Cell membrane
- Mitochondria
- Grana
Animal Cell:
- Round Sphere
- Cell Membrane
- Mitochondria
Grana:
- Many membrane discs inside chloroplasts
- Membranes hold chlorophyll
