32. The cell theory was developed with the help of the light microscope.
The cell theory states that:
1. all organisms are composed of cells
2. cells are the basic unit of structure and function in living things
3. cells come from pre-existing cells

33. Cell Theory People:
a. Anton von Leeuwenhoek  saw living things in pond water
b. Robert Hooke  named the cell
c. Matthias Schleiden  plants made of cells

34. d. Theodore Schwann  animals made of cells
e. Rudolph Virchow  all cells come from other cells

35. Total Magnification = eyepiece(ocular lens) x objective lens
Eyepiece = 10x Objectives = 10x, 40x Greatest possible magnification = 400x
Ex. Total magnification 600x = Eyepiece 10x X Objective 60x

36. Under the microscope, letters get put upside down and backwards.
Ex. “J” appears as “___”.

37. Parts of the microscope:

40. nucleus– controls the cell (where DNA is found)
Ribosomes – site of protein synthesis (make proteins)

Endoplasmic reticulum– series of channels that act as a transport system

41. Golgi Apparatus – packs, sorts and ships molecules
Mitochondria –powerhouse; makes energy; site of cellular respiration
chloroplast – site of photosynthesis

43. Plant cells are different from animal cells in three ways:
plant cells have a cell wall, animal cells do not
plant cells have chloroplasts, animal cells do not
plant cells have larger vacuoles

Guided Notes

58. Cell Membrane
The Cell membrane (plasma membrane) is made up of two layers of lipid, so it is called a lipid bilayer

59. Proteins can also be found inside the membrane
Proteins can also be found inside the membrane. They can act as receptors, channels and pumps.
The lipid bilayer contains phospholipid molecules with nonpolar tails and polar heads.

60. Their hydrophobic tails are “water hating”, while the hydrophilic heads are “water loving”.
They are arranged in the membrane with the tails together and the heads on the outside.

62. Most biological membranes are “selectively permeable”, or some substances can pass across the membrane while others cannot

63. The semi permeability of the cell membrane is most closely associated with the maintenance of homeostasis.
Two main types of transport are active and passive.

64. Passive Transport – does not require energy; moves molecules from high concentration  low concentration.
diffusion – molecules move from high  low
osmosis – water moves from high  low (water moves from less salt to more salt)
facilitated diffusion– large molecules move from high  low through a transport protein

65. Active Transport – requires energy (ATP); moves substances from low concentration  high concentration.
equilibrium – the concentration of dissolved substance is the same throughout a system.

66. What happens to a cell when …
it is placed in a solution with a higher salt concentration – it will shrink
it is placed in a solution with the same salt concentration – stays the same
it is placed in a solution with lower salt concentration – it will swell and burst

67. Photosynthesis is the conversion of sunlight into chemical energy.

68. Equation: CO2 + H2O + Light  C6H12O6+ O2
Carbon Dioxide + Water + Light  Glucose (sugars) + oxygen
Photosynthesis occurs in the chloroplast and the sunlight required for the reaction is absorbed by the chloroplast pigment chlorophyll.

69. There are 2 stages to photosynthesis:
1. light reactions (Electron Transport Chain)
2. Calvin Cycle (dark reactions)

70. Cellular Respiration is the process that releases energy by breaking down glucose and other food molecules in the presence of oxygen.
Equation: C6H12O6 + O2  CO2 + H20 + ATP (energy)
Glucose + oxygen  Carbon Dioxide + water + ATP

71. Cellular respiration occurs in the mitochondria.
The most energy is made during aerobic cellular respiration (36 ATP / molecule of glucose)
There are 3 stages to aerobic cellular respiration:
Glycolysis
Kreb’s Cycle
Electron Transport Chain

72. Anaerobic respiration occurs when there is a lack of oxygen for the cells.
Anaerobic respiration has 2 stages:
Glycolysis
fermentation

73. There are 2 types of fermentation:
Lactic Acid
Forms lactic acid as a byproduct.
Lactic acid creates sore muscles after exercising.

74. Alcoholic
Forms ethanol as a byproduct.
Used in making alcohol.
