Why are lysosomes important to the health of cells?(1 point) Responses
They allow cell organelles to move freely through the cell as needed.
They create cell boundaries and make cells rigid.
They break down worn-out cell parts that are no longer needed.
They move proteins around the cell.
They break down worn-out cell parts that are no longer needed.

The plant would not be able to make glucose and oxygen.
Roots are underground and are not exposed to sunlight.
Prokaryotes lack membrane-bound organelles.

What would happen to a plant if the chloroplasts in its cells became damaged?(1 point) Responses
The plant would not make glucose and oxygen.
The plant would be unable to make protein.
The plant would be unable to reproduce.
The plant would not have a rigid structure.
Using your understanding of the function of chloroplasts and specialized cells, infer why plant root cells lack chloroplasts.(1 point) Responses
Roots require fewer nutrients.
Root cells have two central vacuoles.
Roots are underground and are not exposed to sunlight.
Root cells have many mitochondria.

Prokaryotes lack a cell membrane on the outside.
Prokaryotes lack membrane-bound organelles.
Prokaryotes use RNA instead of DNA.
Prokaryotes lack ribosomes to make proteins.
