Which membrane-bound cell organelle consisting of a small sac-like structure surrounded by single membranes serves as the

cell's digestive system, allowing material taken from outside the cell to degrade and digest obsolete omponents of the cell?

Lysosome

Peroxisome

Glyoxysome

Polysome

Let’s break down the options:

- Lysosome

- This is the one you’re looking for. Lysosomes are small, membrane-bound sacs packed with enzymes.

- They break down waste materials, cellular debris, and stuff the cell brings in from outside.

- Basically, these are the cell’s garbage trucks and recycling plants rolled into one.

- Peroxisome

- These also have enzymes but focus more on breaking down fatty acids and detoxifying harmful substances—not general cell digestion.

- They’re important for metabolic tasks but aren’t the main digesters.

- Glyoxysome

- Found mostly in plant cells, especially seeds.

- Help convert fats into sugars during germination.

- Not really about digesting cell junk.

- Polysome

- Not a sac or membrane-bound at all.

- It’s a bunch of ribosomes attached to one mRNA strand—it helps ramp up protein production, nothing to do with digestion.

So lysosome is the answer. The rest either do something totally different or don’t even fit the description.
