Exploring Cells Edit

Objectives for this lesson: Edit

1. Observe, draw, label and measure cells based on specific guidelines. make sure your right

2. Observe and identify certain organelles of plant and animal cells.

3. Observe the effect of salt solution on Elodea leaf cells.

4. Compare the structure of various cells for evidence that they are suited to their functions.

N.J. Core Curriculum Content Standards Edit
