Idea for Classroom Use

Cells are the smallest functional units of life in all organisms. Ask students, do all cells look the same? Which structures might be the same in both a plant and an animal cell? Which might be different?

Have students read and discuss the Plant Cell and Animal Cell infographics. In pairs, have students create a Venn diagram (or use the one provided) comparing and contrasting the two types of cells. When finished, have student discuss their findings as a class, summarizing the similarities and differences noted.

Ask students, how do cell structures relate to their function? One example of this is that plant cells have chloroplasts that allow them to perform photosynthesis for energy, but animal cells do not have chloroplasts since they get their energy elsewhere.      


organisms that have a well-defined shape and limited growth, can move voluntarily, acquire food and digest it internally, and can respond rapidly to stimuli.


smallest working part of a living organism.


part of the cell in plants and other autotrophs that carries out the process of photosynthesis.


living or once-living thing.


process by which plants turn water, sunlight, and carbon dioxide into water, oxygen, and simple sugars.


organism that produces its own food through photosynthesis and whose cells have walls.
