Animal cell
Nucleus Cell membrane Ribosomes Mitrochondria Cytoplasm
Plant cell
All
Cell wall
vacuole
chloroplast
Artery function
Carries oxygenated blood from heart to organs
Except pulmonary artery
Artery structure
Thick muscular walls as under a lot of pressure
Vein function
Carry blood from body to heart deoxygenated
Vein structure
Thin walls blood under low pressure has valves
Capillaries function
Exchange of gases nutrients and waste products between blood and veins
Capillaries structure
1 cell thick
Low blood pressure
Found in muscles and lungs
Magnification

Arthur Luther Martin
Structure of heart
Deoxygenated Oxygenated
Right Left
Atrium
Ventricle
Why is left side thicker
It pumps blood to rest of body
Cardiac output triangle
Cats outside
Sometimes very
Happy running
Order for blood
Rv, pa, (lungs), pv,la,lv,a,(body),vc,ra
Cardiac output
Volume of blood forced into aorta per min
Stroke volume
Volume of blood forced into aorta per contraction
Heart rate
Number of times heart beats per min
Photosynthesis
Carbon. Light
Dioxide +water-> glucose+oxygen
Chlorophyll
Limiting factors
Light intensity
Carbon dioxide
concentration
Temp
Guard cells
Open- gain water through osmosis was become turgid open and allow co2 to enter
Close-loose water through osmosis reducing water loss on hot windy days
Control- transpiration and photosynthesis
Transpiration
Enters through roots Moves for cell to cell through osmosis Travels up stem by xylem Water lost through stomata Conditions that inrease this high temp windy
Translocation
Glucose produced in chloroplast
Dissolves to form sucrose
Sucrose transported and used for energy transported in phloem
Sucrose can be packaged and used as starch
Nitrogen cycle
Nitrogen fixing- special bacteria convert nitrogen gas to ammonia which the plants use.
Day 1/5
Menstruation lining breaks down
Day 6-14
Uterus lining thickens new egg matures
