6 multiple choice 1 point
identify the organelle in the image above.
lysosome
mitochondria
endoplasmic reticulum
nucleus
clear my selection

Explanation:

• Mitochondria generate ATP through cellular respiration.
• Lysosomes contain digestive enzymes that break down waste materials.
• Rough Endoplasmic Reticulum is studded with ribosomes and involved in protein synthesis.
• Nucleus contains the cell's genetic material.
• The ability of a cell membrane to allow some molecules to pass while keeping others out is called selective permeability.
• The organelle in the image with a characteristic double - membrane and cristae is mitochondria.

Answer:

• Mitochondria: Generate ATP through cellular respiration
• Lysosomes: Contains digestive enzymes that break down waste materials
• Rough Endoplasmic Reticulum: Studded with ribosomes; involved in protein synthesis
• Nucleus: Contain cell's genetic material
• 5. A. Selective Permeability
• 6. B. Mitochondria
