In the start of the light cycle, light-dependent reactions harness energy from the sun in order to create chemical bonds. These bonds are known as ATP and NADPH. These are the molecules that carry energy which are made in the stroma. The stroma is where the Calvin cycle takes place.
<h2>Anterior-posterior orientation</h2>
Explanation:
Flatworms have an anterior-posterior orientation and as a result more coordinated and deliberate movement is established
- Flatworms also called Platyhelminthes are a phylum of relatively simple soft-bodied invertebrate animals
- They are the largest phylum of acoelomates and are found in marine,freshwater and even in some damp terrestrial environments
- Movement in some flatworms is controlled by longitudinal,circular and oblique layers of muscle
- Flatworms anterior end helps in moving towards their food while the posterior end ensures that these organisms walk away from irritants
