Plant cells have plastids essential in photosynthesis. They also have a further layer termed cell wall on their cell exterior.
The fossil record of animals goes back about 600 million many years for the Ediacaran period of time, or rather before.
Hydrothermal vent mussels and shrimps Most animals rely on biomass and bioenergy made by vegetation and phytoplanktons (collectively known as producers) as a result of photosynthesis.
