Which of the following statements about the evolution of early plants is most accurate? Question 4 options: A) Competition for light drove the evolution of plants that could use the red light that reached deeper down into the water. B) There is no CO2 in water, so plants were limited to living at the surface where their leaves could be exposed to the air. C) Early aquatic plants evolved vascular tissue to move photosynthate around the plant. D) Some early plants evolved cellulose to add protection in the harsher environments. E) Heterotrophs were the largest threat on land to early autotrophs moving to live on land.

A. There is too much oxygen in the water B. There is no carbon dioxide in the water. C. The chloroplasts do not function underwater. D. The available light is less intense underwater
