Mitochondria are the powerhouses of the cell, producing ATP through cellular respiration, which provides energy for cellular functions.
Photosynthesis is the process by which plants, algae, and some bacteria convert carbon dioxide and water into oxygen and glucose, using sunlight as energy.
Solar panels convert sunlight (light energy) directly into electricity (electrical energy) through the photovoltaic effect.
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.
Roots absorb water and minerals from the soil and anchor the plant securely in place.
