Biology
Across
- 2. The scientific study of living organisms and their interactions with each other and their environments.
- 5. The liquid component of blood, where blood cells are suspended.
- 7. Organelles in eukaryotic cells responsible for generating energy in the form of ATP through cellular respiration.
- 9. Systems: The skeletal system, providing support, protection, and assistance in movement.
- 10. Cells: Cells that have specific structures and functions suited to perform particular tasks in the body.
- 16. Organisms composed of multiple cells.
- 19. Tissue that contracts to produce movement in animals.
- 20. Membrane-bound sacs within cells that store substances such as water, nutrients, or waste products.
- 21. Wall: A rigid outer layer that provides structural support to plant cells, fungi, and some bacteria.
- 22. A structure made up of different tissues working together to perform specific functions in the body.
- 25. The central organelle that contains the genetic material (DNA) and controls cellular activities.
Down
- 1. Cellular structures that synthesize proteins.
- 3. Organelles in plant cells that conduct photosynthesis, converting light energy into chemical energy.
- 4. The gel-like substance within cells that surrounds the organelles.
- 6. Relating to the process of breaking down food into absorbable nutrients.
- 8. System: The system of the heart and blood vessels responsible for circulating blood throughout the body.
- 11. Tissue: A group of similar cells working together to perform a specific function.
- 12. Pertaining to the circulation of fluids, often referring to the circulatory system.
- 13. The basic structural and functional units of living organisms.
- 14. Specialized structures within a cell that perform specific functions, e.g., mitochondria, nucleus, chloroplasts.
- 15. A simple sugar that serves as a primary source of energy in living organisms, particularly through cellular respiration.
- 17. Membrane: Also known as the plasma membrane, it surrounds the cell, regulates what enters and exits the cell, and provides structural support.
- 18. Cells: Eukaryotic cells found in plants, characterized by a cell wall, chloroplasts, and a central vacuole.
- 23. Tissue that transmits electrical impulses in animals.
- 24. Cells: Eukaryotic cells found in animals, lacking a cell wall and often having a round or irregular shape.
