Mitochondria are the powerhouses of the cell, producing ATP through cellular respiration, which provides energy for cellular functions.
Solar panels convert sunlight (light energy) directly into electricity (electrical energy) through the photovoltaic effect.
Photosynthesis is the process by which plants, algae, and some bacteria convert carbon dioxide and water into oxygen and glucose, using sunlight as energy.
Roots absorb water and minerals from the soil and anchor the plant securely in place.
The outer core is a liquid layer composed mostly of iron and nickel, and it lies beneath the mantle and surrounds the solid inner core.
