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. 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 were formed when other human cells divided. the cells cannot be represented by models because their structures are too complex.

Explanation:

1. For the statement "Each cell has a cell membrane and a cytoplasm that contains cell parts": Both cheek cells (eukaryotic) and red blood cells (though red blood cells lose nucleus and some organelles in maturity, they still have a cell membrane and cytoplasm with components) follow this. All cells (prokaryotic or eukaryotic) have a cell membrane and cytoplasm with cell parts (even if reduced in RBCs).
2. For "Each cell contains parts that work together to carry out processes necessary for life": Cells are functional units, and their organelles/structures (like in cheek cells: nucleus, organelles; in RBCs: membrane, cytoplasm with hemoglobin) work for life processes (e.g., cheek cells for tissue function, RBCs for oxygen transport).
3. For "The cells were formed when other human cells divided": Cell division (mitosis for cheek cells, and red blood cells originate from hematopoietic stem cells via division and differentiation) is how new cells are formed in the human body.
4. For "The cells cannot be represented by models because their structures are too complex": This is false. Models (like 3D models, diagrams) are used to represent cell structures, even complex ones. So this statement is incorrect, but the first three are true. Wait, but in the given image, all four are checked, but we need to identify true ones. So correcting: The fourth statement is false. So the true statements are the first three. But based on the question to select true statements, let's re - evaluate:

• Cheek cells are eukaryotic, red blood cells (mature) are anucleated but still have cell membrane and cytoplasm. So "Each cell has a cell membrane and a cytoplasm that contains cell parts" is true (RBC has cytoplasm with hemoglobin etc.).
• Cells have parts (organelles, structures) that cooperate for life processes (e.g., cheek cells: metabolism, RBCs: oxygen transport), so this is true.
• Cells arise from pre - existing cells (cell division), so this is true.
• Cells can be modeled (diagrams, 3D models, computer models), so the fourth statement is false. So the true statements are:
• 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 were formed when other human cells divided.

Answer:

• 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 were formed when other human cells divided.
