The color of a star is primarily determined by its surface temperature.
For example, the really hot stars, called White Dwarf stars, have a white surface temperature, while a cooler star would have a more red color.
Both plant and animal cells have a mitochondria! Plant cells have a cell wall, a cell membrane and a chloroplast. Animal cells have a lysosome, where as plant cells usually don't have this present.
If a plant just did photosynthesis then the plant would not have any food and just an abundant amount of ATP. they use cellular respiration to make food they can use to grow
