Multiple Choice

Students conduct an investigation of plant cells and turgor pressure. They observe and draw the cells shown below. Each cell is from a different plant exposed to a different environment. The cells in the drawings have different shapes due to differences in turgor pressure.

• In cell B water inside the vacuole applies a pulling force on the inside of the cell walls.

• In cell A water inside the vacuole applies an outward pushing force on the cell walls.

• In cell A air on the outside of the cell applies a pulling force on the cell walls.

• In cell B the cytoplasm on the inside of the cell applies a pushing force on the cell walls.

Multiple Choice

Which of the following is true according to cell theory?

• All cells are produced by other cells

• Not all cells grow and develop.

• All cells have chloroplasts.

• Not all organisms are composed of cells

Multiple Choice

In the 1830’s botanist Matthias Schleiden and anatomist Theodor Schwann observed the cells of organisms. They found that plants and animals are both composed of cells. Over a decade later biologist Rudolph Virchow expanded this idea, proposing that all organisms are made of cells. Scientific understanding of cells has continued to grow since this time. Which of the following statements is true about plant and animal cells?

• Both plant and animal cells use energy from food.

• Only animal cells use energy from food.

• Only plant cells contain genetic information.

• Both plant and animal cells make their own food.

Multiple Choice

Students observed and classified the following items into two groups. Which of the following is the most likely criteria used to group the items?

• things that photosynthesize and things that don’t

• plants and things that plants need

• things made up of cells and things that are not made of cells

• multicellular organisms and unicellular organisms

Multiple Choice

Which structures differentiate plant cells from animal cells?

• nucleus, large vacuole, mitochondria

• cell wall, chloroplast, mitochondria

• nucleus, cell wall, chloroplast

• cell wall, chloroplast, large vacuole

Multiple Choice

What is the function of a chloroplast?

• provide support for the cell

• direct all the cells activities

• use energy from sunlight to make glucose

• regulate substances that enter and exit the cell

Multiple Choice

• 1

• 2

• 3

Multiple Choice

The diagram below shows an animal cell and the organelle it contains. What is the function of the cell organelle number 4 in the diagram of a cell shown above?

• store water for the cell

• convert sunlight into chemical energy

• control the activities of the cell

• provide energy for the cell to use

Multiple Choice

The respiratory system is responsible for gas exchange in the body. It takes oxygen into the body and releases carbon dioxide. The lungs are a major organ in the respiratory system. Which of the following identifies the levels of organization that make up the respiratory system in order of increasing complexity?

• lung cell, tissue, lung, respiratory system

• lung, respiratory system, tissue, lung cell

• tissue, lung cell, lung, respiratory system

• respiratory system, tissue, lung cell, lung

Multiple Choice

The leaf of a plant is composed of xylem tissue that carries water, and phloem tissue that carries food, and is covered with a waxy, protective epidermis tissue. What is the structural level of organization of a plant leaf?

• Tissue

• Organism

• Organ

• Cell
