Answer: Some substances pass through small holes in the surface cell membrane. This is called diffusion and does not require the cell to expend energy. Oxygen gets into a cell and carbon dioxide (the product of respiration reactions) leaves it this way. ... small particles (ions or molecules) diffuse more quickly than large ones.
Explanation:
I’m sure the answer is early ancestor.
Answer:
Diffusion- Passive transport
energy required- Active transport
exocytosis- Active transport
osmosis- Passive transport
endocytosis- Active transport
energy not required- Passive transport
facilitated diffusion- Passive transport
Protein pumps- Active transport
Explanation:
Passive transport can be described as the transport of particles along the concentration gradient i.e from an area of higher concentration to an area of lower concentration. This process does not require energy. For example, the phenomenon of osmosis
Active transport can be described as the transport of particles against the concentration gradient i.e from an area of lower concentration to an area of higher concentration. This process requires energy. For example, exocytosis
