Review for the Seven Organelles

A runner is competing in a 10 km track meet and just before completing the race, the runner is nearly out of breath and the energy needed to finish the race. Which cell structure is most affected by this lack of energy?

• Nucleus

• Ribosomes

• Mitochondrion

• Plasma Membrane

What can be used to distinguish between eukaryotic and prokaryotic cells?

• Only eukaryotic cells come from preexisting cells.

• Only prokaryotic cells are the smallest unit of living organisms.

• Only prokaryotic cells contain ribosomes.

• Only eukaryotic cells contain membrane-bound organelles.

The diagram above shows a plant cell. Which structure is found in plant cell but is absent in an animal cell?

• 1

• 2

• 3

• 4

Which Organelle is correctly paired with its function

• Ribosomes-site of energy production

• Vacuole-storage of excess water

• Nucleus-converts light energy into chemical energy

• Chloroplast-controls cell activities

Which of the following is the correct order for the levels of a multicellular organisms from the simplest part to the most complex?

• Tissue→Organs→Cells→Organ Systems→Organism

• Cells→Tissue→Organs→Organ Systems→Organism

• Organism→Organ System→Organs→Tissue→Cells

• Organs→Tissues→Cells→Organ System→Organism

The inner membrane of the mitochondria consists of a series of folds. How might this be advantageous to the cell?

• It increases surface area for energy production

• It allows for more efficient conversion of light energy to chemical energy

• It reduces the need for transport proteins

• It creates a specialized compartments for lipid storage

What structure is most directly responsible for maintaining homeostasis in a cell?

• Chloroplast

• Cell Wall

• Plasma Membrane

• Vacuole

Studies of fats cells and muscle cells show that fat cells have fewer mitochondria than muscle cells. A biologist would most likely infer that fat tissue:

• Requires less protein than muscle tissue

• Requires an equal amount of energy as muscle tissue

• Requires more protein than muscle tissue

• Requires less energy than muscle tissue

A diagram of a cell is shown here, in which structure is protein synthesized?

• 1

• 2

• 3

• 4

Which 2 organelles contain their own DNA and ribosomes and therefore are thought to have lived on their own at one time?

• nucleus and Golgi apparatus

• mitochondria and chloroplasts

• lysosomes and vesicles

• Rough ER and Smooth ER
