A plant without chlorophyll would not be able to photosynthesise because chlorophyll serves to absorb sunlight, which is used to break apart the bonds in water during photosynthesis. A plant that is unable to photosynthesise is not able to create glucose, hence it would likely die unless it was receiving glucose through another source. This is because the plant relies on the energy it gets from breaking down glucose for important internal functions.
Scientists use fossils to study earth history by identifying the fossil and what era it came from. By knowing what era the fossil came from and what location it was found, scientists can make assumptions about the earth formation at that time.
False in a sense because it is not random. It is just that some organisms have more advantageous characteristics than others. These genes are then passed on which makes the likelihood of the next generation surviving greater.
