Two Types of Cells Prokaryotic and Eukaryotic

Prokaryotic NO nucleus or Organelles Bacteria

Eukaryotic Cells Have a nucleus and organelles Plant cells, animal cells

Organelles:

Plant/Animal Cell Nucleus- Control Center, Holds DNA Cell Membrane- Controls what enters and leaves the cell Mitochondrion- Makes ATP (energy) Ribosome- Makes Proteins

Plant Cells Only Cell Wall- Protection Chloroplasts- Photosynthesis

Transport Cell membrane- controls what enters or leaves the cell. Semi-permeable- some things can go through, some things cannot.

Everything wants to be: Equal

How do we flow? High to Low (NO energy Needed) Diffusion- movement of particles from high to low, NO energy Osmosis- Movement of water from High to low, NO energy

From Low to High- You MUST BUY! ENERY (ATP) is needed Active Transport- movement of molecules from Low to high

Osmosis Hypotonic Solution: High Water- Cell Swells Hypertonic Solution: Low Water- Cell Shrinks Isotonic Solution: Equal Water- Cell Stays the same

Photosynthesis CO2 + H2O + Sunlight → C6H12O6 + O2 Plants do it. Happens in the Chloroplast (Green) Formula CO2 + H2O + Sunlight → C6H12O6 + O2 Produces Oxygen Gas

Cell Respiration C6H12O6 + O6 → H2O + CO2 + ATP ALL LIVING things do it Happens in the Mitochondrion Opposite of Photosynthesis Formula C6H12O6 + O6 → H2O + CO2 + ATP

Two Types Aerobic- with oxygen Anaerobic- without oxygen Humans: Lactic Acid Formation Yeast/Bacteria: Alcoholic Fermentation
