  1. 2. The scientific study of living organisms and their interactions with each other and their environments.
  2. 5. The liquid component of blood, where blood cells are suspended.
  3. 7. Organelles in eukaryotic cells responsible for generating energy in the form of ATP through cellular respiration.
  4. 9. Systems: The skeletal system, providing support, protection, and assistance in movement.
  5. 10. Cells: Cells that have specific structures and functions suited to perform particular tasks in the body.
  6. 16. Organisms composed of multiple cells.
  7. 19. Tissue that contracts to produce movement in animals.
  8. 20. Membrane-bound sacs within cells that store substances such as water, nutrients, or waste products.
  9. 21. Wall: A rigid outer layer that provides structural support to plant cells, fungi, and some bacteria.
  10. 22. A structure made up of different tissues working together to perform specific functions in the body.
  11. 25. The central organelle that contains the genetic material (DNA) and controls cellular activities.

  1. 1. Cellular structures that synthesize proteins.
  2. 3. Organelles in plant cells that conduct photosynthesis, converting light energy into chemical energy.
  3. 4. The gel-like substance within cells that surrounds the organelles.
  4. 6. Relating to the process of breaking down food into absorbable nutrients.
  5. 8. System: The system of the heart and blood vessels responsible for circulating blood throughout the body.
  6. 11. Tissue: A group of similar cells working together to perform a specific function.
  7. 12. Pertaining to the circulation of fluids, often referring to the circulatory system.
  8. 13. The basic structural and functional units of living organisms.
  9. 14. Specialized structures within a cell that perform specific functions, e.g., mitochondria, nucleus, chloroplasts.
  10. 15. A simple sugar that serves as a primary source of energy in living organisms, particularly through cellular respiration.
  11. 17. Membrane: Also known as the plasma membrane, it surrounds the cell, regulates what enters and exits the cell, and provides structural support.
  12. 18. Cells: Eukaryotic cells found in plants, characterized by a cell wall, chloroplasts, and a central vacuole.
  13. 23. Tissue that transmits electrical impulses in animals.
  14. 24. Cells: Eukaryotic cells found in animals, lacking a cell wall and often having a round or irregular shape.
