Explanation:

• First question: Lysosomes are membrane - bound organelles that contain hydrolytic enzymes. The interior of lysosomes is acidic (pH around 4.5 - 5.0). These enzymes can break down various biomolecules such as proteins, nucleic acids, lipids, and carbohydrates. Ribosomes are involved in protein synthesis. Centrosomes are important for organizing microtubules during cell division. The Golgi complex is mainly involved in modifying, sorting, and packaging proteins and lipids.
• Second question: Active transport is the movement of molecules or ions against their concentration gradient (from an area of lower concentration to an area of higher concentration). This process requires energy (usually in the form of ATP) because it goes against the natural tendency of molecules to move down their concentration gradient. Facilitated diffusion and diffusion (including osmosis, which is the diffusion of water) are passive transport mechanisms that do not require the cell to expend energy as they move molecules down their concentration gradient.

Answer:

• First question: Lysosomes
• Second question: Active transport
