Students examine microscopic life by conducting a scientific investigation. In this cell analysis lesson, students define the prokaryotic and eukaryotic cells and discuss their word origins. Students view each type of cell on slides...

Students observe the general structure and organelles of plant and animal cells. Students prepare microscope slides of elodea, onion, check, and cork and identify the cells by size and shape as unicellular, multicellular, plant or animal.

Take a peek inside a plant or animal cell, and examine the structure and function of each organelle.

Take an interactive quiz over the classification of living things. After completing the quiz, check your score, and then revisit any incorrect question for further review.
