The innermost matrix of chloroplasts, called the stroma, contains metabolic enzymes and multiple copies of the chloroplast genome. Chloroplasts also have a third internal membrane called the thylakoid membrane, which is extensively folded and appears as stacks of flattened disks in electron micrographs.
No, animal cells do not contain chloroplast because chloroplast functions as the source of photosynthesis. Chloroplast is part of the Plastid group, which are specific organelles which specifically function in organic plant organisms. This group, in general, supplies the energy storage and the synthesis of metabolic materials, e.g. photosynthesis.
