Carbon dioxide passes through the plasma membrane of cells by:
Correct answer: D. Simple diffusion
- A. Active transport
- B. Phagocytosis
- C. Facilitated diffusion
- D. Simple diffusion
Explanation

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
