What problem may occur after injury if platelets are deficient?
Answer and explanation
Correct answer: Blood clotting will be difficult
Platelets are small cell fragments in the blood that gather at an injured site and help initiate clot formation. A clot forms a temporary seal over a damaged blood vessel, reducing blood loss and supporting repair. If platelet numbers are low, clotting becomes slower or inadequate, so bleeding may continue for longer after an injury. Therefore option A is correct; the other choices are unrelated effects involving oxygen, digestion, or plant stomata.
