Cell (Intro) | Ch 6
All organisms are made of cells, the simplest collection of matter.
Electron Microscope (Types)
Scanning: Create 3D Images of a cell's structure
Transmission: Study a cell's internal ultrastructure
Cell Fractionation (Basics & Tools)
Separates cells to its organelles which helps us study its function by using a Centrifuge
What 4 organelles are in every cell type?
- Plasma Membrane
- Cytosol (Semifluid)
- Chromosome (Carry Gene)
- Ribosome (Make Protein)
Prokaryotic (Basics & DNA & Associations)
Has no nucleus or membrane bound organelles so the DNA is in the nucleoid.
Includes Bacteria & Archaea.
Eukaryotics (Basic & Associations)
Has a nucleus and membrane bound organelles.
Includes Protists, Fungi, Animals, and Plants
Eukaryotics vs. Prokaryotics in Size.
Eukaryotics are larger. But their size is limited by cellular metabolism.
Light: Focuses Light. For Cells, Nucleus, & Bacteria.
Electron: Focuses Electron. For Organelles, Bacteria, & Atoms.
What 3 organelles are in animal cells only?
Lysosomes, Centrosomes, and Flagella
What 4 organelles are in plant cells only?
Chloroplasts, Central Vacuole, Cell Wall, and Plasmodesmata
