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
