Multiple Choice

Why was the development of photosynthesis so important to the evolution of life on Earth?

It led to the formation of the ozone layer, which protected life from harmful UV radiation.

It facilitated the development of multicellular organisms by increasing the availability of nitrogen.

It allowed for the conversion of solar energy into chemical energy, providing a sustainable energy source for living organisms.

It enabled the synthesis of complex carbohydrates, which are essential for DNA replication.

Verified step by step guidance

Photosynthesis is a process used by plants, algae, and some bacteria to convert light energy, usually from the sun, into chemical energy stored in glucose, a type of sugar.

The development of photosynthesis was crucial because it allowed organisms to harness solar energy and convert it into a form that could be used to fuel various biological processes.

This process involves the absorption of light by chlorophyll, a green pigment in the chloroplasts of plant cells, which then uses this energy to convert carbon dioxide and water into glucose and oxygen.

The oxygen produced as a byproduct of photosynthesis was released into the atmosphere, leading to the development of an oxygen-rich environment, which was essential for the evolution of aerobic (oxygen-using) organisms.

The ability to convert solar energy into chemical energy provided a sustainable and abundant energy source, supporting the growth and complexity of life forms on Earth, including the development of multicellular organisms.
