Lysosomes are important to the health of cells because they break down worn-out cell parts that are no longer needed. This process helps in recycling cellular components and maintaining cellular homeostasis.

The plant would not have a rigid structure.
If the chloroplasts in a plant's cells became damaged, the plant would not make glucose and oxygen. Chloroplasts are essential for photosynthesis, the process by which plants convert light energy into chemical energy, producing glucose and oxygen as byproducts.
