In this context, the term "Response area" seems to refer to specific organelles or structures within eukaryotic cells that play crucial roles in maintaining cellular functions. Based on the descriptions provided, it appears that "Response area" can be completed with terms such as "nucleus," "plasma membrane," "mitochondria," "vacuole," and "chloroplast" depending on the specific function being described.
Therefore, the completed passage might look something like this:
- "The nucleus is responsible for housing genetic material that controls the activities of the cell."
- "The plasma membrane forms the boundary that controls what enters and leaves both the plant and animal cell."
- "The mitochondria help the cell to function because they break down glucose, also known as sugar, to provide the cell with energy."
- "The vacuole is a structure that allows the cell to store things like food and waste."
- "The plant cell also contains chloroplasts, which are structures that are not found in the animal cell. This is because they allow the plant cell to do photosynthesis and make its own food."
So, the final answer for "Response means ______." could be words like "nucleus," "plasma membrane," "mitochondria," "vacuole," or "chloroplast," depending on the specific definition applicable to the context provided.
