Sample Questions/Answers

• (Note: Specific answer choices are included, these are examples and may not be exhaustive.)*

• Anton Van Leeuwenhoek: Famous for observing single-celled protists, blood cells, and bacteria under a microscope.

• Microscopic cork observations: Conducted by Robert Hooke, these were the first records of cells.

• Prokaryotic Cell Examples: Bacteria.

• Eukaryotic Cell Characteristics: DNA bunched together in the middle, with organelles not covered by a membrane. Cells also have a nucleus and are not bacteria.

• Homeostasis Purpose: To keep cells alive.

• Cell characteristics shared by all cells: Surrounded by a cell wall (or membrane), containing DNA, cytoplasm, organelles; some have nuclei.

• Cell Theory Components: Cells come from existing cells, the cell is a structural and functional unit in organisms, all living things are made of cells.

• Cell Parts: Study diagrams and their functions (e.g., 7-2A and 7-2B)

• Cell Parts and Functions: Understand the function of each part of a cell, like the ribosomes, Golgi body, nucleus and other cellular structures like endoplasmic reticula.

• Materials making cells: Recognize components like lipids, protein and carbohydrates that make up cell membranes.

• Processes in cell function: Learn about diffusion, osmosis and active transport

• Photosynthesis location: Occurs in chloroplasts

• Photosynthesis inputs: Carbon dioxide, water

• Photosynthesis output: Carbohydrate/glucose

• Cellular Respiration location: Occurs in mitochondria

• Cellular Respiration output: ATP (energy)

• Cell Materials: Use the examples of water, food, wastes and other substances that make up a cell

• Microscopes and stains: Understand cell components using microscope functions
