Question

think about cell theory and the cell models you have seen. then, select the true statements at these human cells. the cells cannot be represented by models because they belong to a multicellular organism. the cells were formed when other human cells divided. each cell has a cell membrane and a cytoplasm that contains cell parts. each cell carries out processes that are necessary for life.

Explanation:

• Cell theory states that all cells come from pre - existing cells. So, the statement "The cells were formed when other human cells divided" is true.
• All cells (prokaryotic and eukaryotic) have a cell membrane and cytoplasm. Human cells are eukaryotic, so "Each cell has a cell membrane and a cytoplasm that contains cell parts" is true.
• Each cell, whether it is a red blood cell, brain cell, heart cell or eye cell, carries out processes like metabolism (e.g., energy production through cellular respiration) which are necessary for life. So, "Each cell carries out processes that are necessary for life" is true.
• Cells of multicellular organisms can be represented by models. For example, we can have models of animal cells (which human cells are a type of) to show their structure. So, "The cells cannot be represented by models because they belong to a multicellular organism" is false.

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 carries out processes that are necessary for life.
