Eukaryotes


Organisms with
genetic
material enclosed in a
nucleus
Eukaryotes


Have genetic material enclosed in a
nucleus
Have
cytoplasm
Have a
cell membrane
Prokaryotes


Lack a
nucleus
Have
genetic
material in a single
loop
and plasmids
May have a
cell wall
,
cell membrane
, and cytoplasm
Sperm cells


Have
half
the
genetic
information
Have a
long tail
Have
mitochondria
Have
enzymes
Nerve cells


Transmit impulses with long axons
Have myelin
insulation
Have
dendrites
for connectivity
Muscle
cells


Contract
Contain
protein
fibers
Have
mitochondria
for
energy
production
Root hair cells


Increase
surface
area
Lack
chloroplasts
Xylem cells


Have
thick walls
with
lignin
Have no
internal structures
Are for
water transport
Phloem cells


Contain
vessel
cells
Have
sieve plates
for
sugar movement
Have
companion
cells for
energy supply
Bacterial Division


Bacteria multiply via
binary
fission every
20
minutes
Stem cells


Undifferentiated cells found in
bone marrow
or
embryos
Stem cells


Useful in leukemia treatment by forming new
bone marrow
and
blood cells
Stem Cells in Leukemia Treatment
1.
Destroy
existing bone marrow with
radiation
2.
Transplant
donor bone marrow for new cell
formation
Therapeutic
cloning

Creates
embryos
with patient genes for
immune system-friendly
transplants
Some
objections
exist to embryonic stem
cells
due to ethical concerns
Upper
and lower
epidermis


Protect the leaf
Stomata


Allow
gas exchange
Guard cells


Regulate
stomata
opening
Palisade
mesophyll

Contains
chloroplast-packed
cells
Spongy mesophyll


Aids in
gas diffusion
Xylem


Transports
water
Phloem


Transports
sugars
Meristem


Contains
stem
cells for
growth
Transpiration


1. Constant
evaporation
of water from
leaves
2. Replaced from
roots
3. Cools the
leaf
4. Aids in
mineral transport
Pathogens


Bacteria
,
viruses
, protozoa, and fungi that cause communicable diseases
Digestive enzymes


Catalyze reactions, break down proteins,
starch
, and
lipids
into simpler forms
Cardiovascular diseases


Involve
fatty
deposits in coronary arteries
Treated with
statins
and
stents
Faulty
heart valves can be replaced with mechanical or
animal
valves
Cancer


Mitosis
regulation prevents
tumor growth
Genetic
and
environmental
factors can lead to cancer development
