Cell membrane: The semi-permeable layer surrounding the cell that controls what enters and exits the cell, maintaining homeostasis (no specific author or date provided).
Nucleus: The control center of the cell that contains genetic material (DNA) and regulates activities such as growth and reproduction (no specific author or date provided).
Mitochondria: Organelles known as the "powerhouses" of the cell, responsible for producing energy through aerobic respiration (no specific author or date provided).
Ribosomes: Tiny structures where protein synthesis occurs, translating genetic instructions into proteins (no specific author or date provided).
Chloroplasts: Organelles found in plant cells that contain chlorophyll and are the site of photosynthesis, converting light energy into chemical energy (no specific author or date provided).
Cell wall: A rigid outer layer found in plant, fungi, and some prokaryotic cells that provides structural support and protection (no specific author or date provided).
