|
The cell would produce more proteins than it needs.
|
|
|
The cell would have chloroplasts that appear yellow rather than green.
|
|
|
The cell would be less able to break down molecules in its cytoplasm.
|
|
|
The cell would be less able to regulate the amount of fluid in its cytoplasm.

Detailed explanation-1: -Answer: C-The cell would be less able to break down molecules in its cytoplasm. Lysosomes are cellular organelles that contain digestive enzymes that help break down and recycle cellular waste, including molecules in the cytoplasm.
Detailed explanation-2: -If lysosomes get ruptured in a cell, the cell dies due to release of hydrolytic enzymes which destroys the cellular components.
Detailed explanation-3: -So, the correct answer is ‘Cell dies’.
Detailed explanation-4: -The completed autophagosome or amphisome fuses with a lysosome, which supplies acid hydrolases. The enzymes in the resulting compartment, an autolysosome, break down the inner membrane from the autophagosome and degrade the cargo. The resulting macromolecules are released and recycled in the cytosol.
Detailed explanation-5: -Lysosomes are major degradative organelles in eukaryotic cells. Their luminal pH is acidic ( 5), and a variety of acid hydrolases in their lumen achieve their degradative function.
