Question

compartments in eukaryotic cells
note – use this slide as a quiz. write out what you know and then look back at your notes and add to your answer in a different color
compartments

• nucleus →
• endoplasmic reticulum →
• golgi apparatus →
• vesicles →
• lysosomes →
• microsomes - peroxisomes →
• mitochondria →
• chloroplasts →
• vacuoles →

Explanation:

To answer about the compartments in eukaryotic cells, we can describe each:

• Nucleus: Contains genetic material (DNA), controls cell activities, site of transcription.
• Endoplasmic Reticulum (ER): Rough ER (with ribosomes) synthesizes proteins; Smooth ER synthesizes lipids, detoxifies, stores calcium.
• Golgi Apparatus: Modifies, sorts, packages proteins/lipids from ER for transport (vesicles) or secretion.
• Vesicles: Small membrane sacs; transport materials (e.g., from ER to Golgi, or for exocytosis/endocytosis).
• Lysosomes: Contain hydrolytic enzymes; digest macromolecules, recycle cell components (autophagy).
• Peroxisomes (and Microsomes): Peroxisomes break down fatty acids, detoxify (e.g., H₂O₂); Microsomes (ER fragments) are used in lab studies.
• Mitochondria: “Powerhouse”; aerobic respiration, ATP production (via oxidative phosphorylation).
• Chloroplasts (in plant/algal cells): Site of photosynthesis; convert light energy to chemical energy (glucose).
• Vacuoles (large in plants): Store water, nutrients, waste; maintain turgor pressure, aid in cell growth.

If the task is to list/explain these, the above covers key functions/roles. For a quiz, writing these details (then adding more from notes) would work.
