question 4 (4 points)
(02.03 lc)
which best describes the function of chloroplast?
a allows certain molecules to enter and exit the cell
b makes food during photosynthesis
c detoxifies waste products
d packages proteins into vesicles

Explanation:

First Question (Which organelle contains enzymes to break down waste?)

• Option a: Chloroplasts are involved in photosynthesis, not waste breakdown.
• Option b: Lysosomes contain hydrolytic enzymes that break down waste materials, cellular debris, and foreign invaders in the cell.
• Option c: Mitochondria are the powerhouses of the cell, producing ATP (energy), not breaking down waste.
• Option d: Ribosomes are involved in protein synthesis, not waste breakdown.

• Option a: The cell membrane (or plasma membrane) controls the entry and exit of molecules, not chloroplasts.
• Option b: Chloroplasts contain chlorophyll and are the site of photosynthesis, where plants (and some other organisms) make food (glucose) using light energy, carbon dioxide, and water.
• Option c: Organelles like peroxisomes or lysosomes (in some cases) are involved in detoxification, not chloroplasts.
• Option d: The Golgi apparatus is responsible for packaging proteins into vesicles, not chloroplasts.

Answer:

b. Lysosome
