Living Environment Regents Review
Lesson 2
1. A structure that performs a specialized function within
a cell is known as
(1) a tissue
(2) an organelle
(3) an organ
(4) a system
2. The ribosome is an organelle that functions in the
process of
(1) phagocytosis
(2) pinocytosis
(3) protein synthesis (4) cellular respiration
3. Which organelle is correctly paired with its function?
(1) nucleus — provides carbohydrates for
fermentation
(2) chloroplast — serves as a site for photosynthesis
(3) centriole — synthesizes digestive enzymes
(4) lysosome — packages cellular products
4. In plant cells, which organelle is most closely
associated with aerobic respiration?
(1) mitochondrion
(2) chloroplast
(3) lysosome
(4) nucleolus

9. Which structures carry out life functions within cells?
(1) tissues
(2) organ systems
(3) organelles
(4) organs
10. Homeostasis in unicellular organisms depends on the
proper functioning of
(1) organelles
(2) insulin
(3) guard cells
(4) antibodies
11. After a cell was treated with a certain chemical, the
ribosomes stopped functioning. Which cell activity
was immediately affected by this change in ribosome
function?
(1) intracellular transport
(2) protein synthesis
(3) aerobic respiration
(4) excretion of metabolic wastes
12. Which metabolic process is most closely associated
with the organelle represented in the diagram below?
5. Which organelle contains hereditary factors and
controls most cell activities?
(1) nucleus
(2) cell membrane
(3) vacuole
(4) endoplasmic reticulum
6. The function of the contractile vacuole in many
freshwater protozoans is to
(1) store carbon dioxide
(2) aid in mechanical digestion
(3) eliminate wastes such as ammonia
(4) eliminate excess water
(1) intracellular digestion
(2) aerobic respiration
(3) synthesis of glycogen
(4) hydrolysis of lipids
7. Some plants remove excretory products from the
cytoplasm by
(1) excreting them by pinocytosis
(2) transporting them into vacuoles for storage
(3) secreting them into cell nuclei
(4) eliminating them by the action of contractile
vacuoles
8. Which structures are found in every living cell?
(1) a plasma membrane and cytoplasm
(2) chloroplasts and mitochondria
(3) a cell wall and nucleus
(4) centrioles and chromosomes

13. The diagram below represents two cells, X and Y.
Which statement is correct concerning the structure
labeled A?
(1) It aids in the removal of metabolic wastes in
both cell X and cell Y.
(2) It is involved in cell communication in cell X, but
not in cell Y.
(3) It prevents the absorption of CO 2 in cell X and 0 2
in cell Y.
(4) It represents the cell wall in cell X and the cell
membrane in cell Y.
14. Studies of fat cells and thyroid cells show that fat cells
have fewer mitochondria than thyroid cells. What
would a biologist most likely infer about fat tissue?
(1) it does not require energy
(2) it has energy requirements equal to those of
thyroid tissue
(3) it requires less energy than thyroid tissue
(4) it requires more energy than thyroid tissue
15. One difference between plant and animal cells is that
animal cells do not have
(1) a nucleus
(2) chloroplasts
(3) a cell membrane
(4) centrioles

Lesson 2
Base your answer to questions 16 through 18 on on the information below and on your knowledge of
biology. The diagrams represent two different cells and some of their parts. The diagrams are not drawn to
scale.
16. Identify the organelle labeled X in cell B.
17. Identify an organelle in cell A that is the site of autotrophic nutrition.
18. Which statement best describes these cells?
(1) Cell B lacks vacuoles while cell A has them.
(2) DNA would not be found in either cell A or cell B.
(3) Both cell A and cell B use energy released from ATP.
(4) Both cell A and cell B produce antibiotics.
Base your answer to questions 19 through 21 on the diagrams below of two cells, X and Y, and on your
knowledge of biology.
19. State one function of the organelle that you identified in the previous question.
20. Select one lettered organelle and write the letter of that organelle in the space below. Identify the organelle
you selected.
21. Identify one process that is carried out in cell Y that is not carried out in cell X.
