Yes, all cells have energy. Cells require a constant supply of energy to function, grow, and reproduce. This energy comes from the chemical bonds of organic molecules, such as sugars, which are broken down through processes like cellular respiration.
- Plants: Plants produce their own food through photosynthesis, converting sunlight into energy stored in sugars.
- Animals: Animals obtain energy by consuming plants or other animals, breaking down the organic molecules in their food.
The ultimate source of energy for almost all cells is the Sun. Photosynthetic organisms like plants capture sunlight and convert it into chemical energy, which is then passed along to other organisms through the food chain.
