D. Both are sources of energy because Carbohydrates provide the cells for short term energy but lipids store the energy for when it's needed.
Answer:
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
things needed to carry out the photosynthesis:
- Chlorophyll. Chlorophyll, the pigment in plants that makes them green, is essential to the photosynthetic process.
- Sunlight. The process cannot work without an energy input, and this comes from the sun.
- Water
The process of photosynthesis is commonly written as:
6CO2 + 6H2O → C6H12O6 + 6O2
This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll into a sugar molecule and six oxygen molecules, the products.
