Lysosomes are important to the health of cells because they break down worn-out cell parts that are no longer needed. They contain enzymes that digest cellular debris, helping to recycle components and maintain cellular health.
Why are lysosomes important to the health of cells?(1 point) Responses They move proteins around the cell. They move proteins around the cell. 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 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.

Which of the following organelles provide structure and rigidity to a plant cell?(1 point) Responses chloroplast chloroplast ribosome ribosome cell membrane cell membrane cell wall
The organelle that provides structure and rigidity to a plant cell is the cell wall.
What would happen to a plant if the chloroplasts in its cells became damaged?(1 point) Responses The plant would be unable to make protein. The plant would be unable to make protein. The plant would not have a rigid structure. The plant would not have a rigid structure. The plant would be unable to reproduce. The plant would be unable to reproduce. The plant would not make glucose and oxygen.
If the chloroplasts in a plant's cells became damaged, the plant would not make glucose and oxygen. Chloroplasts are responsible for photosynthesis, the process by which plants convert sunlight, carbon dioxide, and water into glucose and oxygen.
Using your understanding of the function of chloroplasts and specialized cells, infer why plant root cells lack chloroplasts.(1 point) Responses Roots are underground and are not exposed to sunlight. Roots are underground and are not exposed to sunlight. Root cells have many mitochondria. Root cells have many mitochondria. Root cells have two central vacuoles. Root cells have two central vacuoles. Roots require fewer nutrients.
Plant root cells lack chloroplasts because roots are underground and are not exposed to sunlight. Since chloroplasts are responsible for photosynthesis, which requires light, root cells do not need them as they do not participate in this process.
What is the main difference between prokaryotic and eukaryotic cells?(1 point) Responses Prokaryotes lack a cell membrane on the outside. Prokaryotes lack a cell membrane on the outside. Prokaryotes use RNA instead of DNA. Prokaryotes use RNA instead of DNA. Prokaryotes lack ribosomes to make proteins. Prokaryotes lack ribosomes to make proteins. Prokaryotes lack membrane-bound organelles.
The main difference between prokaryotic and eukaryotic cells is that prokaryotes lack membrane-bound organelles. Eukaryotic cells have organelles that are surrounded by membranes, while prokaryotic cells do not have these membrane-bound structures.
