Cells (types) Flashcards
Cells
There are many types of cells but they can all be categorized as either Prokaryotic or Eukaryotic
- The basic unit of all living things.
- Are made up of “little organs” called organelles.
EUKARYOTE
Eukaryotes
Any cell that is not bacteria (includes plants and animals)
•Larger
•Newer, more recently evolved
•Have membrane-bound organelles
•Have membrane bound nucleus that contains DNA in double helix (chromosomes)
Two Main Types of Eukaryotes that we are familiar with are
PLANTS and ANIMALS
Lysosomes, nucleus, nucleolus, Golgi body, centrioles, mitochondria, vacuole, chloroplast, rough and soft ER
Flagella, pseudopodia, cytoskeleton, chromosomes, cilia, cell membrane, cytoplasm, ribosomes, cell wall
PROKARYOTE
Prokaryotes •Bacteria •Very small •Oldest cells on Earth •Very simple: No membrane- bound organelles including a nucleus •DNA circular found in cytoplasm
Flagella, pseudopodia, cytoskeleton, chromosomes, cilia, cell membrane, cytoplasm, ribosomes, cell wall
Typical plant cell
- Has cell wall (Plant Skeleton)
- Has chloroplasts (for photosynthesis)
- Square shape
- Have Cell Membrane •Have Mitochondria •Have Nucleus
- Have Ribosomes •No Lysosomes
Vacuole, chloroplast, cell wall
Flagella, pseudopodia, cytoplasm, cytoskeleton, nucleolus, chromosomes, cilia, nucleus, Golgi body, cell membrane, ribosomes, mitochondria, rough and soft ER
Typical bacteria
- No Nucleus (DNA tangled in cell)
* No Chloroplasts •NO Mitochondria •Have Cell Membrane •Have Ribosomes
Typical animal cell
- No cell wall
- No chloroplasts •Have Cell Membrane •Have Mitochondria •Have Nucleus
- Have Ribosomes
Lysosomes, centrioles
Flagella, pseudopodia, cytoplasm, cytoskeleton, nucleolus, chromosomes, cilia, nucleus, Golgi body, cell membrane, ribosomes, mitochondria, rough and soft ER
Organelles
- Cell Membrane- Acts as boundary and bouncer determining what comes in and what gets out (phospholipids)
- Nucleus- Contains DNA (genetic information) “Brain of cell”
- Ribosomes- Makes protein (RNA gives code from DNA –translation)
- Chloroplasts- performs Photosynthesis (makes sugar from sunlight)
- Mitochondria- performs Cellular Respiration- Breaks sugars and releases usable energy
