• Nucleus Passive transport
• DNA Diffusion
• Mitochondria Osmosis
• E.R. Cellular respiration
• Ribosomes Photosynthesis
• Cell membrane Concentration gradient
• Cell wall Glucose
• Chloroplast

4
CELL CLASSIFICATION

• There are two kinds of cells
• Prokaryotic cells- have no membrane around their
  nuclear material
• Example- bacteria
• Eukaryotic cells- have membrane-bound nucleus and
  many organelles
• Example- plant and animal

5
Types of Cells

• Cells are the basic units of organisms.
• Basic types of cells

Eukaryotic
Prokaryotic
Bacterial Cell
Animal Cell
Plant Cell
6
Cellular Organelles and Functions

• Nucleus- controls cellular activities
• Golgi bodies- package proteins
• Mitochondria- energy producer, site of cellular
  respiration
• Endoplasmic Reticulum- highway out of the nucleus
  for cellular products
• Rough- has ribosomes
• Smooth- no ribosomes

7
Cellular organelles- continued

• Vacuoles/vesicles-storage
• Cell membrane- barrier
• Cell wall- barrier in plant cell
• Chloroplast-site of photosynthesis in plant cell
• Ribosomes-site of protein synthesis
• Lysosomes- waste management
• Cytoplasm- cell soup where organelles sit

8
Cellular Transport

• There are two kinds of cellular transport-
• 1. Active transport-
• Requires energy in the form of ATP
• Used when moving large molecules in or out of
  cell
• Going against the concentration gradient
• Needs transport proteins in membrane

9

• 2. Passive Transport
• Uses no energy
• Diffusion movement of particles from areas of
  high concentration to low concentration (With the
  concentration gradient)
• Osmosis movement of water with the concentration
  gradient
• CO2 , O2 , H2O all cross cell membranes using
  passive transport

10
CONCENTRATION GRADIENT

• Over time, molecules in areas of high
  concentration naturally flow to areas of low
  concentration until an equilibrium on both sides
  of the membrane is reached.

Diffusion in Lungs
12
Osmosis- High to low is the natural flow

Cellular Processes

• Photosynthesis- occurs in chloroplast of
  plant cell
• Uses carbon dioxide and water
• Makes glucose and oxygen
• Cellular respiration- occurs in
  mitochondria
• Uses glucose and oxygen
• Makes carbon dioxide and water and ATP!!!

EQUATIONS for REACTIONS

• Photosynthesis
• 6CO2 6H2O ? C6H12O6 6O2
• Cellular Respiration
• 6O2 C6H12O6 ? 6CO2 6H2O
• What do these equations have in common?
