Detailed explanation-1: -The hypothesis that plants had evolved from species of green algae is associated with the prediction that if green algae and plant members will have similarities in their genomic sequence, then the hypothesis is valid.
Detailed explanation-2: -Scientists believe that green algae and plants have a common ancestor because both organisms undergo photosynthesis and they have similar cell walls. They have the same chlorophyll and store food in the form of starch. They both go through a two stage reproduction.
Detailed explanation-3: -You can place bottles in different amounts of sun to determine how much sunlight is ideal for algae growth. Instead of testing algae, try using duckweed, a small green plant. Duckweed is ideal to test because you can actually count the number of plants that grow under your various conditions.
Detailed explanation-4: -The correct answer is D: Photosynthesis is most active in those wavelengths of light and thus more oxygen is produced by the algae in those regions.
