STAAR Review Day Five Independent Practice
1. Cells of the epithelial tissue are packed closely together in layers. How do epithelial cells protect organs within
the human body?
a. Epithelial cells fight invading bacteria and viruses by entering them and destroying their DNA
b. Epithelial cells provide oxygen to organ cells so that the organs can repair any damage they sustain
c. Epithelial cells form a barrier between the external environment and the internal structures of the body
d. Epithelial cells can change into organ cells through cellular differentiation.
2. Photosynthesis occurs in the leaves of the plant. Leaves absorb light. They take in carbon dioxide during
photosynthesis and take in oxygen during respiration. What specialized role do guard cells have in
photosynthesis?
a. Guard cells contain chloroplasts in which photosynthesis occurs
b. Guard cells convert carbon dioxide into oxygen and water
c. Guard cells store excess food made during photosynthesis
d. Guard cells regulate the opening and closing of the stoma to prevent water loss.
3. In humans, the respiratory system allows for the release of carbon dioxide produced during cellular
respiration and for the intake of oxygen for use during that same process. This process is similar to
which structure in plants?
a. The release of oxygen and intake of carbon dioxide for cellular respiration from the roots
b. The release of oxygen and intake of carbon dioxide for cellular respiration from the stomata
c. The release of oxygen and intake of carbon dioxide for photosynthesis from the roots
d. The release of oxygen and intake of carbon dioxide for photosynthesis from the stomata
4. During a game of tag, how are human body systems interacting to maintain homeostasis
a. The endocrine system is increasing the heart rate which will increase blood flow to muscles, the
nervous is releasing sweat to cool down body, integumentary is sending messages around the
body, and respiratory is increasing in rate to help bring in more oxygen/release more CO 2
b. The endocrine system is producing hormones to increase heart rate which will increase blood
flow to muscles (circulatory), the nervous is not involved during this process, and the
integumentary is increasing in rate to help bring in more oxygen/release more CO2
c. The endocrine system is producing hormones to increase heart rate which will increase blood
flow to muscles (circulatory), the nervous is sending messages to the body to move faster and
move away from “danger”, integumentary is releasing sweat to cool down body, and
respiratory is increasing in rate to help bring in more oxygen/release more CO2
5. A neurologist that specializes in neuroanatomy does several experiments to determine how the structure of a
neuron affects its function. In one of her experiments, she uses a microscalpel to cut off a neurons dendrites.
How do you think this experiment will change the function of a neuron?
The neuron will no longer be able to receive messages because it is missing its dendrites therefore it will not be
able to function at all
6. Sickle cell anemia is a condition caused by a mutation in the gene that encodes for red blood cells. This point
mutation causes red blood cells to be sickle shaped instead of disk shaped. How do you think his change in the
structure of the red blood cells affects their function in patients that have this disease?
Because red blood cells are disk shaped they can go through small blood vessels easily, if they are now sickle
shaped they will not be able to flow through the body which will starve cells of oxygen.
