Figure 1.3 Some properties of life

How do these organisms get ENERGY? What do they need ENERGY for?. Figure 1.3 Some properties of life. Cell Energy. Work is done when anything is moved. This biological work demands energy. The cellular form of ENERGY is ATP. ATP stands for Adenosine Triphosphate. ATP.

Photosynthesis Part 2

Photosynthesis Part 2. In green plants, photosynthesis occurs within organelles called chloroplasts . Chloroplasts contain photosynthetic membranes arranged in flattened sacs called thylakoids which contain chlorophyll. Thylakoids are arranged in stacks called grana .
