Photosynthesis takes place inside plant cells in small things called chloroplasts<span>.</span>
Answer:
Fossils are the remains of ancient plants and animals that were buried millions of years back. These are found to be embedded in the sedimentary types of rocks. The earliest known direct fossils are not obtained in the present day, but the imprints of these fossils are explored in many of the places. These were the ancient micro-fossils such as bacterias, cyanobacteria that existed about 3.5 billion years back.
Some of the direct evidence of fossils are obtained from the rocks in the western part of Australia and the southwestern part of Greenland.
Thus, the imprints of these fossils are found in many rocks at different places, and this suggests the existence of life during that particular time frame.
Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results. -ally :)

The second one is a bit too big I will send it right now.
