Final Exam Review

Practice with the cell models: name and function of each part

#1 Nucleus Controls with DNA

#2 Cytoplasm Fills cell, holds water, holds cell organelles

#3 ER (transport tubes) Tunnels for movement inside cell

#4 Ribosomes Make protein (enzymes, antibodies, hormones, muscles)

#5 Mitochondria Makes energy from food

#6 Chloroplast Makes glucose from light and CO2 (photosynthesis)

#7 Cell wall Protects plant cell only, made of starch called cellulose

#8 Cell membrane Diffusion : movement of water, food and waste in and out of cell

#9 Vacuole Hole for storage of food, water and waste

Which is animal, which is plant? How do you know? Plant has cell wall and chloroplast

How do you make a vaccine to a virus? Use these words to fill in the blanks antibodies, T4 (wbc) cells, inject, BAM, chemical given by a Dr., immune, kill

So it should read A ) kill a virus using chemicals, heat and radiation (why?) Inject the virus into an animal (why not a plant? Animal will make antibodies using T4 (memory) cells from the immune system Next time animal see the real virus, BAM the T4 cells kill it dead

Antibiotic Chemical given by a Dr. to treat a bacteria

Best way to prevent the spread of disease Wash your hands with soap and water

Pumps blood to deliver food, hormones, O2 and CO2 circulatory

Exchanges O2 for CO2 at the alveoli Respiratory

Breaks big molecules into small molecules so they fit inside a cell digestive

Ovaries and testes reproductive

T4 cells and other wbc to fight off infection immune

Makes chemical hormones that control EVERYTHING! Endocrine

Movement, includes tendons and soft tissue Muscular

Homeostasis Keeping body in balance

How does respiratory and circulatory systems work to maintain homeostasis? Respiratory brings in oxygen Circulatory spreads the oxygen to your body

Dominant gene R; always shows

Recessive gene.r ; only shows if there is 2 recessive genes

Co-dominant gene RW; 2 traits share

RR x rr Write the cross (see above) ___ % wrinkled ____ % round
