Answer:
1)All cells have a plasma membrane, ribosomes, cytoplasm, and DNA.
2)Mitochondria are oval-shaped, double-membrane organelles
3) DNA makes RNA makes Protein. ... The synthesis of proteins occurs in two sequential steps: Transcription and Translation.
4) The main chemical produced by oxidation in peroxisomes is the very cytotoxic (cell toxic) hydrogen peroxide. Fortunately peroxisomes produce copious amounts of the enzyme catalase and this helps break down hydrogen peroxide to water and oxygen.
5) Nucleus is a large, centrally located spherical component of cell. It is enclosed by two nuclear membranes, collectively called nuclear envelope that are connected to the endoplasmic reticulum. Nuclear envelope contains many nuclear pores and encloses the nucleoplasm (liquid ground substance).
