Standard 3

Students will understand that the organs in an organism are made of cells that have structures and perform specific life functions.

Objective 1

Observe and describe cellular structures and functions.

• 1. Use appropriate instruments to observe, describe, and compare various types of cells (e.g., onion, diatoms).

  2. Observe and distinguish the cell wall, cell membrane, nucleus, chloroplast, and cytoplasm of cells.

  3. Differentiate between plant and animal cells based on cell wall and cell membrane.

  4. Model the cell processes of diffusion and osmosis and relate this motion to the motion of particles.

  5. Gather information to report on how the basic functions of organisms are carried out within cells (e.g., extract energy from food, remove waste, produce their own food).
