Question

which of the following statements is not true about the evolution of plants? the earliest cells to use photosynthesis gave off oxygen. the earliest plant forms were bryophytes. the earliest plant cells did not use the sun's energy for food. the first photosynthetic cells were prokaryotes.

Answer 1

plant cells have always used the suns energy for food through photosynthesis, so 3 is false

Answer 2

Ans. option). the earliest plant cells did not use the sun's energy for food.

Plants are photosynthetic, autotrophic organisms that use sunlight to make their food. Like other plant cells, earliest plant cells, such as cells of moss and liverworts also used sun's energy and chlorophyll to make food from inorganic nutrients.

Thus, the statement 'the earliest plant cells did not use the sun's energy for food' is not true about the plant evolution.
