Question Why are lysosomes important to the health of cells?(1 point) Responses They create cell boundaries and make cells rigid. They create cell boundaries and make cells rigid. They break down worn-out cell parts that are no longer needed. They break down worn-out cell parts that are no longer needed. They allow cell organelles to move freely through the cell as needed. They allow cell organelles to move freely through the cell as needed. They move proteins around the cell. They move proteins around the cell.
The correct response is: They break down worn-out cell parts that are no longer needed.
Lysosomes are important to the health of cells because they break down worn-out cell parts that are no longer needed.
Which of the following organelles provide structure and rigidity to a plant cell?(1 point) Responses chloroplast chloroplast cell membrane cell membrane ribosome ribosome cell wall
The correct response is: cell wall. The cell wall provides structure and rigidity to a plant cell.
The correct answer is: They break down worn-out cell parts that are no longer needed.
Lysosomes are membrane-bound organelles that contain enzymes capable of breaking down a variety of molecules, such as proteins, carbohydrates, lipids, and nucleic acids. These enzymes help in the process of digestion and recycling within the cell.
To find the answer, you can eliminate the incorrect options by understanding their functions:
- "They create cell boundaries and make cells rigid" is incorrect because lysosomes are not involved in cell boundary formation or rigidity.
- "They allow cell organelles to move freely through the cell as needed" is incorrect because the function described here is performed by the cytoskeleton, not lysosomes.
- "They move proteins around the cell" is incorrect because protein transport is performed by other organelles like the endoplasmic reticulum and Golgi apparatus.
By the process of elimination, the correct answer is "They break down worn-out cell parts that are no longer needed." Lysosomes play a crucial role in cellular recycling and maintenance by breaking down unused or damaged cellular components, such as organelles, debris, and macromolecules. This process, called autophagy, helps maintain the health and proper functioning of cells.
