Prokayote Cell
No nucleus and no membrane bound organelles
Ex
: bacteria
Eukaryote Cell
Nucleus and membrane bound organelles
Sexual Reproduction
(+)Produces gentically different offspring
1 disease not likely to kill all
(-)have to find mate
Asexual Reproduction
(-)Produces identical individuals
1 disease could wipe out population
(+)no mate
Autotroph
Make own energy (from sunlight)
Ex
: plant
Heterotroph
Consume others
Homeostasis
stay in balance
Ex
: sweat/shiver/sugar levels
Adaptations
Physical
: part of body
Behavioral
: the way they act
Growth of cells
More cells
Development of cells
specialized cell (differientation)
Organization
cell>tissue>organ>organ system>organism
Reasons cell differientation doesn't work correctly
Mutation
When you add an
enzyme
catalyst
to the
reactants
it reduces the
activation energy
to make
products
.
Draw water molecule
4 Reasons H

O is important
transport
chemical reactions
specific heat
controls temp.
Solute
being dissolved (particles)
Solvent
Dissolves particles

Covalent Bonds
share electrons
Ionic Bonds
held together by opposite charges
Adhesion
stick to a solid
Cohesion
water sticks to water (hydrogen bond)
Buffers
Prevent pH from changing
Importance of Carbohydrates
Energy

Importance of glucose
main source of energy
Four different polysaccharides
starch (plants store excess glucose)
glycogen (animals store excess glucose)
chitin (exoskeleton)
cellulose (cell of plant-fiber)
Importance of Proteins
structural (muscle)
functional (enzymes)
How enymes work
Substrate fits into active site of enzymes like a key and the enzyme changes shape causing substrate to break into products
Importance of consuming lipids
stored energy
cell membrane
Key characteristic of Lipids and characteristic's importance
Doesn't dissolve in H
2
O
Keeps things from getting inside or outside
Makes up cell membrane
Momomer of Carbs
monosaccharide
Monomer of Proteins
Amino Acids
Monomer of Lipids
Fatty Acids
Monomer of Nucleic Acids
nucleotides
Importance of 2 Nucleic Acids
DNA
: genetic blueprint
RNA
: makes proteins- AA
Types of Lipids
Saturated/Unsaturated
Wax
Steroids
Phospholipids
Cilia
small hair-like structure
used for movement
Ex
: humans/paramecium
Organelle
structure within a cell that carries out a specific function
Endocytosis
when a cell takes in a large particle
Diffusion
movement of particles from high to low concentration
Osmosis
movement of water from high to low concentration
Why cells are the size they are
Depends on surface area vs. volume
Why Cells are shaped a specific way
Function of a cell
Ex
: skin cell (flat- surface)
Robert Hooke
discovered first cell
dead cork
Anton van Leeuwenhoek
1st living cell
moving in pond water
Robert Brown
1st organelle
nucleus (biggest organelle)
Cell membrane
selectively premeable
fluid mosaic model
Ribosomes
make proteins
Rough ER
transports ribosomes
Smooth ER
transports carbs and lipids
Mitochondria
makes ATP
cristae (membrane)
own DNA
glucose to ATP
Both cells
Vacuole
storage
Nucleus
Command center
directs all organelles
Golgi Apparatus (Bodies)
"Post office"
package, process, secrete
Vesicles
Transport
Cloroplast (Plastids)
absorb sunlight to make sugar
own DNA
sunlight to glucose
plant cells only
Cilia
movement
hair-like structure
Nucleolus
make ribosomes
Lysosomes
contain digestive enzymes
Ex
: food, waste, orld cell
disease- Tay Sach syndrome
(star-shaped)
Cell Wall
Plant only
supports and protects
Flagella
movement
long-whip
Ex
: sperm
Hypertonic solution
solute concentration is hight in the solution than in cell
Hypotonic solution
solute concentration is lower in solution than in the cell
Isotonic solution
solute concentration is equal inside and outside of cell
Passive transport
doesn't use energy
High to Low
no ATP
Active Transport
uses energy
Low to High
ATP
Facilitated Diffusion
use protein to hel go across membrane
high-low
Sodium Potassium Pump
every two potassium for every 3 sodium
