What This Standard Means
What Students Need to Do
- Students observe cells and use what they see to explain that living things are made of cells. They explain that cells carry out life processes and that new cells come from existing cells.
What Mastery Looks Like
- A student can identify cells in onion tissue and explain that a single yeast cell is alive. They can point to a cell division sequence as evidence that new cells come from existing cells.
Common Misconceptions
- Some students think only animals have cells, or that one cell is too small to be alive. Others think new cells appear from nothing as an organism grows.
How to Assess It
- Give students images of onion tissue, one yeast cell, and a cell dividing. Ask them to write what each image shows about cells.

Ways to Teach It
Use a microscope to view onion skin and a drop of yeast water, then sketch the cells you see.
Show a sequence of root tip cell division images. Ask, “What evidence shows where new cells come from?”
Play an evidence sort: match images of onion tissue, yeast, and dividing cells to claims about cells.
Show a risen loaf and a yeast micrograph. Ask how gas made by living yeast cells helped the dough rise.
