Unit 1 Review: cell theory, organelles, levels of organization

In the 1800s two scientists, Theodor Schwann and Matthais Schleiden, studied different types of organisms. After many years of studying a great variety of organisms, they drew similar but independent conclusions about their observations.

Which answer choice best describes the cell theory?

• The functions of living things occur in cells.

• Cells exist only in multicellular organisms.

• Living things are composed of cells.

• Cells contain hereditary information.

Which list gives the correct characteristics for prokaryotic or eukaryotic cells?

• Prokaryotic Cells: single-celled and have DNA in a nucleus

• Eukaryotic Cells: contain DNA in nucleus, contain membrane-bound organelles

• Prokaryotic Cells: DNA in cytoplasm, include membrane-bound organelles, found in all plants

• Eukaryotic Cells: found only in single-celled organisms, have flagella, no nucleus

Eukaryotic cells and prokaryotic cells have some parts that are different. Which of the following would you find only in a eukaryotic cell?

• A nucleus

• A cell membrane

• DNA in the cytoplasm

• Organelles without membranes

Plants use energy from sunlight, water, and carbon dioxide to produce sugar. Which structure is found only in plant cells and helps plants capture energy from sunlight?

• Cell wall

• Chloroplast

• Vacuole

• Nucleus

Students view two different cells under a microscope. They record their observations in the table shown. Based on the organelles observed, the students determine that cell 2 is a plant cell because it has an organelle that -

• Allows water to enter and exit the cell.

• Contains genetic material.

• Stores water and nutrients.

• Produces its own food.

Which of the following lists includes cellular structures found in both plant and animal cells?

• Chloroplasts, cell wall, cell membrane, cytoplasm

• Vacuoles, cell membrane, nucleus, mitochondria

• Cell membrane, cytoplasm, nucleus, cell wall

• Chloroplasts, vacuoles, cell wall, cytoplasm

The nucleus is a round, double-membrane structure often found in the center of both plant and animal cells. Its function is to -

• Purify water.

• Store fat.

• Generate cytoplasm.

• Contain genetic material.
