Question

cheek cells red blood cells think about cell theory and the cell models you have seen. then, select the true statements about these human cells. the cells were formed when other human cells divided. each cell has a cell membrane and a cytoplasm that contains cell parts. each cell contains parts that work together to carry out processes necessary for life. the cells cannot be represented by models because their structures are too complex.

Explanation:

According to cell - theory, all cells come from pre - existing cells. Also, all cells have a cell membrane and cytoplasm with organelles (even if simple in some cases like red blood cells which lack a nucleus but still have other cell parts). Cells have parts that work together for life processes. And cells can be represented by models despite their complexity.

Answer:

The cells were formed when other human cells divided.
Each cell has a cell membrane and a cytoplasm that contains cell parts.
Each cell contains parts that work together to carry out processes necessary for life.
