Mike has four aquatic plants of the same size and the same species. He submerges the plants in a separate beaker filled with 200 ml of water. She then sets each beaker under a different intensity of light. Mike observes that, of the four plants, the plant in the beaker under the most intense light gives off the most gas bubbles in a 20 minute period.Which of the following statements best explains Mike’s observations?

|
Cells decompose most quickly under the most intense light.
|
|
|
Water evaporates from plants faster under the most intense light.
|
|
|
Photosynthesis occurs at the highest rate under the most intense light.
|
|
|
Gases in the leaves of plants expand most under the most intense light

Explanation:
Detailed explanation-1: -The plants can be categorized into four main types. Submerged plants, emergent plants, floating plants, and algae.
Detailed explanation-2: -Hydrilla grows completely submerged under water since it is a aquatic organism.
Detailed explanation-3: -Plants undergo photosynthesis, which is the process where carbon dioxide, water, and sunlight are transformed into sugar and oxygen. Even though they look different than terrestrial plants, aquatic plants, or plants that live on the water’s surface or are submerged underwater, also undergo photosynthesis.
Detailed explanation-4: -Like terrestrial plants, most aquatic plants (other than free-floating plants) derive their nutrients from the sediment or soil.
