•Unicellular
•Can be heterotrophic
or autotrophic
•Protozoans, algae
•Eukaryotic
•Have nucleus
• Some have cell wall
•Mainly unicellular

What shape is “Gina”?
Equilateral triangle
Bryophytes
Gymnosperms
Angiosperms
•Non-vascular
•No xylem or phloem
•Examples are mosses
•They are small
•Have to be near water
•No pollen, seeds, flowers, or fruits
•Vascular
•Xylem to move water
•Phloem to move food
•Examples are conifers
•Have pollen (sperm)
•Have seeds on cones
•No fruits or flowers
•Vascular
•Xylem to move water
•Phloem to move food
•Examples are flowering plants like
oak trees, corn, and roses
•Have pollen (sperm)
•Have seeds in fruits
•Have flowers
ROOT, STEM, LEAF



Roots are adapted to absorb
water with root hairs
Leaves are adapted for
photosynthesis by being flat
and green
Stems move water with
xylem
FLOWERS AND FRUITS






Flowers have bright petals to
attract pollinators
Pollen (Sperm) can be transferred
by animals
When egg joins with pollen, a
seed is formed in the ovary
The ovary becomes the fruit
Fruit surrounds and protects
seed
Fruit also helps get baby plants
in seeds away from parent plant
Annelids
Insects
Amphibians
Mammals
•Segmented worms
•No backbone
•“breathe” through
skin
•Closed circulatory
system
•External fertilization
•External
development
•No backbome
•Three body segments
•Six legs
•Wings
•Open circulatory
system
•External fertilization
•Females may store
sperm
•External
development
•metamorphosis
•Have backbone
•Moist skin
•Gills when young,
lungs when adult
•Three chambered
heart
•Cold-blooded
•External fertilization
•External
development
•Metamorphosils
•Jelly like egg
•Backbone
•Hair
•Milk glands
•Lungs
•Four chambered
heart
•Warm-blooded
•Internal fertilization
•Internal
development
•Amniote egg
VIRUS STRUCTURE
 A virus is not made of
cells
 It is nucleic acid (DNA
or RNA) surrounded by
protein coat (Capsid)
VIRAL REPRODUCTION
•
•
•
Virus can’t reproduce
unless it is inside a living
cell
The virus uses the cells
enzymes and ribosomes to
make DNA and protein
New viruses either bud
off of the cell or the cell
bursts, releasing lots of
viruses
BACTERIA
•
Made of cells
•
Can be killed by
antibiotics
•
Examples of disease
caused by bacteria is
strep throat
VIRUS
•
•
•
•
Not made of cells
MUCH SMALLER THAN
CELLS
Can’t be killed by antibiotics
Example of diseases caused
by viruses are AIDS (HIV),
Smallpox, Influenza
Malaria
Individuals who
have the sickle
cell trait
(heterozygous)
aren’t as affected
as homozygous
individuals
Mosquitoes
transmit malaria
PKU
Individuals who
have PKU can’t
break down
phenylalanine
If it builds up it
can cause mental
retardation
Keep individuals
with
PKU on a diet,
they don’t have
brain damage
Lung
Cancer
Diabetes
Skin
Cancer
Lung cancer is
uncontrolled
growth of cells in
the lungs
Diabetes results
from when the
pancreas fails to
make enough
insulin
Light skinned
people don’t have
the natural
melanin
protection of
darker skinned
people
Individuals who
smoke are more
likely to get lung
cancer
Individuals who
are overweight
and who don’t
exercise seem to
be more affected
Overexposure to
sunlight can
trigger the
changes that lead
to skin cancer
B-cells
T- helper
cells
• White blood
cell
• Make
antibodies
• White blood
cell
• Help
coordinate
immune
response
T-killer cells
• White blood
cell
• Kill virus
infected cell
PASSIVE IMMUNITY
•
•
•
•
•
Person does NOT
make memory cells
or antibodies
Antibodies only are
transferred
Doesn’t provide longterm protection
Natural: from
breastfeeding
Artificial: Rabies
“shot”
ACTIVE IMMUNITY
•
•
•
•
Person DOES make
antibodies AND
memory cells
Provides long term
immunity
Natural: you have
disease
Artificial – you get
a VACCINATION
