Answer:
4) Chloroplasts, 5) An animal cell with a nucleus, 6) many-celled organisms.
Step-by-step explanation:
4) Chloroplasts are organelles present in eukariotic cells that produce food with the help of sunlight via photosynthesis.
5) Every cell has a nucleus. Bacteriae are prokariotic cells, while vegetal and animal cells are eukariotic cells, in which cytoplasm is exclusive for organells. Hence, the right answer is: An animal cell with a nucleus.
6) Specialized cells are cells that help in functioning of many-celled organisms. Therefore, the right choice is: many-celled organisms.
