Structure of Living Organisms

Across

• 1. A jelly-like material that contains dissolved nutrients and salts and structures called organelles. It is where many of the chemical reactions happen. (9)
• 3. Plant and bacterial cell walls provide structure and protection. Only plant cell walls are made from cellulose. (4, 4)
• 4. Tiny structures where protein synthesis occurs. (9)
• 5. It is permeable to some substances but not to others and so controls the movement of substances in and out of the cell. (4, 8)
• 6. These can rotate or move in a whip-like motion to move the bacterium. (8)
• 8. Organelles that contains the enzymes for respiration, and where most energy is released in respiration. (12)
