Answer 1

Ans 1...Yes all the living organism are made up of cells.

Cell is the structural and functional unit of body of any organism.cells furthur form tissue then tissue form organ and then organ form organ system and various organ system then form and work.together as a living body.

Ans 2...diffeence

ans 3...ER and golgi apparatus are highly similar structure so first we need to differentiate these... ribosomes are quite different we can do separately.

Ribosomes....these are tiny struvtures present over the rough endoplasmic reticulum whivh perform the function of translation.they bind to the mRNA and convert it into protein

Ans 4.... function of mitochondria... mitochondria are considered the power house of cell.they are involved in ATP synthesis

Chloroplast ... chloroplast cells are the cells responsible for photosynthesis in plants.these are not found in animals
