Question

which of the following combinations correctly match an organelle with its function?
□ endoplasmic reticulum: site of protein and lipid production
□ golgi apparatus: protein processing and packaging
□ chloroplast: conversion of sunlight energy to usable cellular energy
□ mitochondrion: conversion of food to usable energy
□ lysosome: internal support; cell and organelle movement

Explanation:

• Endoplasmic reticulum synthesizes proteins (rough ER) and lipids (smooth ER).
• Golgi apparatus modifies, sorts, and packages proteins for transport.
• Chloroplasts perform photosynthesis, converting sunlight to chemical energy (glucose).
• Mitochondria carry out cellular respiration, breaking down food to produce ATP (usable energy).
• Lysosomes digest waste, not provide internal support (a function of the cytoskeleton).

Answer:

endoplasmic reticulum: site of protein and lipid production, Golgi apparatus: protein processing and packaging, chloroplast: conversion of sunlight energy to usable cellular energy, mitochondrion: conversion of food to usable energy
