Question

think about cell theory and the cell models you have seen. then, select the true statements about these human cells. 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. the cells were formed when other human cells divided. each cell has a cell membrane and a cytoplasm that contains cell parts.

Explanation:

• Cells have organelles like mitochondria, ribosomes etc. that collaborate for life - sustaining functions, validating the first statement.
• Cells can be represented by models (e.g., animal - cell models), so the second statement is false.
• According to cell theory, all cells come from pre - existing cells, supporting the third statement.
• All human cells have a cell membrane and cytoplasm with cell parts, confirming the fourth statement.

Answer:

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