biology

• Ribosomes are small, spherical organelles responsible for protein synthesis in the cell.
• Mitochondria are responsible for producing energy through aerobic respiration.
• The nucleus contains the genetic material (DNA) that controls all cellular activities.
• The cytoplasm is the gel-like substance inside the cell that contains various organelles and is the site of many cellular processes.
• The cell membrane is a selectively permeable barrier that separates the cell from its environment.
• Chloroplasts are green structures found only in plant cells where photosynthesis occurs.
• The nucleus is the control center of the cell and contains genetic material (DNA).
• Lysosomes break down unwanted materials inside cells using enzymes.
• Vacuoles store water, nutrients, and waste products within cells.
