Stomata are openings found on the underside of leaves that allow gas exchange. An omnivore would eat both insects and seeds as part of its diet. Mitochondria are known as the powerhouse of the cell, as they take in glucose and oxygen during respiration and give off carbon dioxide, water, and energy.
