Review Cells and the organization of life before starting →Ideas to recall
- Cells represent the smallest autonomous structural and functional units capable of sustaining life.
- Prokaryotes lack membrane-enclosed organelles; eukaryotes maintain compartmentalized internal environments.
- Plant cells possess rigid cellulose cell walls, chloroplasts, and large central vacuoles that animal cells lack.
- Multicellular organisms organize specialized cells into tissues, organs, organ systems, and integrated organisms.
Use these ideas to reason through each question; answer-specific explanations appear only after you check a response.
