In this unit you will learn about:
Applying Newton's first law to answer some true/false statements about why objects move (or not).
Plant cells have a cell wall in addition to a cell membrane, whereas animal cells have only a cell membrane. Plants use cell walls to provide structure to the plant. Plant cells contain organelles called chloroplasts, while animal cells do not. Chloroplasts allow plants to make the food they need to live using photosynthesis.
In this lesson you will learn about:
In this unit you will learn about:
