What is sexual reproduction? (between mitosis and meiosis)

Meiosis.

Meisois is is the reproduction of the sex cells (sperm and egg), while mitosis is between a regular cell. Another difference is that Meiosis splits into 4 cells, while mitosis splits into 2.

Hope this helps!

Mitochondria produce atp, a high energy compound. atp is used for all sorts of enzyme-mediated reactions, such as making proteins/nucleotides/etc, certain compounds cross the cell membrane, muscles move, etc.  without this source of energy, a cell will die. it will not be able to repair itself, defend against pathogens, etc.

Ibelieve the answer is a-broad because that is a leafed plant.
