Mitochondria is also known as the powerhouse of the cell. It has a double membrane-bound structure. They are found inside the cytoplasm of the cell and synthesize energy in the form of ATP molecules.
What converts stored food into energy in a cell?
Answer and Explanation: The cell part that converts food into energy is the mitochondria. The mitochondria is an organelle enclosed by two membranes. The mitochondria hosts the second two steps of aerobic cellular respiration, the citric acid cycle and oxidative phosphorylation.
What organelle provides temporary storage of food enzymes and waste products?
In plant cells, temporary storage of food enzymes and waste products is provided by the vacuole. In animal cells, this work is done by the lysosomes.
What is the function of chloroplast?
Chloroplasts are the place for the major conversion of the sun’s radiation energy to chemical energy that is usable by organisms. Accordingly, they account for about 50% of the leaf protein [1], and the enzyme ribulose-1,5-bisphosphate carboxylase of chloroplast is by far the most abundant protein on the Earth [2].
Chloroplasts perform photosynthesis during the daylight hours. The immediate products of photosynthesis, NADPH and ATP, are used by the photosynthetic cells to produce many organic molecules.

How do cells deal with waste?
Cells use both diffusion and osmosis to get rid of their wastes. Cells can bias the movement of waste molecules out of and away from themselves. One way is to temporarily convert the waste product into a different molecule that will not diffuse backwards.
How is waste removed from a cell?
Within a cell, lysosomes help with recycling and waste removal through a number of pathways. Rich in powerful enzymes that can break down molecules and even entire organelles and bacteria, lysosomes fuse with sacs carrying cellular debris (via autophagy) or pathogens from outside the cell (via phagocytosis).
An example of such is cell excretion process. The cell clears its waste products by bringing the waste products close to the cell membrane and then closing the cell membrane around the waste products, isolating it from the rest of the cell.
