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
Cross 2 blue egged platypus’ (Bb)
• B= blue egg• .b= white egg• Predict • % blue egg• % white egg• Get a teacher check
