1) Adenosine Triphosphate (ATP) is the energy currency of cell.Mitochondria release ATP.
2) ER is found in abundant quantity in liver and it lacks ribosomes and functions in lipid manufacture and metabolism, the production of steroid hormones, and detoxification.
3) prokaryotic cells are those that do not have a membrane-bound nucleus and we know that many bacteria donot have proper membrane-bound nucleus therefore organisms like bacteria are called prokaryotic.
4)Chloroplast are green in colour while leucoplast are colourless.
lecucoplast helps in storage of starch, lipids, or proteins while chloroplast helps in the photosynthesis process and in its absence the sun energy cannot be converted in sugar form.
5) Nucleus is the structure where Eukaryotes store their genetic material while nucleoid is the place where Prokaryotes store their genetic material.
Nucleus is large and well organized, whereas nucleoid is small and poorly organized.
