A) nervous system
B) skeletal system
C) digestive system
D) cardiovascular system

This organelle is usually small and round in shape. It breaks down larger food molecules into smaller ones, digests waste, recycles old parts and breaks down a cell quickly after it dies. What is this cell organelle called?
A) vacuole
B) mitochondria
C) cytoplasm
D) lysosome

Respuesta :

1.c

it is proven that the plant cell is shaped by the cell wall whilst the animal cell is shaped by it's membrane (cell membrane) in other terms an animal cell doesn't have cell wall and vacuole
