  1. 1. The living substance within a cell, consisting of cytoplasm and the nucleus.
  2. 3. A group of cells with similar structure and function, working together to perform specific tasks within an organism.
  3. 5. Organisms composed of more than one cell, exhibiting specialized cell types and complex organization.
  4. 6. Thread-like structures composed of DNA and protein, carrying genetic information and located in the nucleus of eukaryotic cells.
  5. 7. Organelles responsible for producing energy (ATP) through cellular respiration, known as the "powerhouses" of the cell.
  6. 9. Membrane-bound organelles containing digestive enzymes, responsible for breaking down waste materials and cellular debris.
  7. 11. Organelles found in plant cells, responsible for photosynthesis and containing chlorophyll pigment.
  8. 12. Cells lacking a true nucleus and membrane-bound organelles, characteristic of bacteria and archaea
  9. 14. membrane A selectively permeable membrane that surrounds the cell, regulating the passage of substances into and out of the cell.
  10. 16. wall A rigid structure that surrounds the cell membrane in plant cells, providing support and protection.
  11. 18. The basic structural and functional unit of all living organisms, capable of independent existence and reproduction.
  12. 19. Units of heredity composed of DNA, containing instructions for the synthesis of proteins and influencing traits in organisms.

  1. 1. Temporary projections of the cell membrane in certain unicellular organisms, used for locomotion and capturing prey.
  2. 2. Cells containing a true nucleus and membrane-bound organelles, characteristic of plants, animals, fungi, and protists.
  3. 4. Organisms consisting of a single cell, capable of performing all necessary life functions independently.
  4. 8. Cellular organelles responsible for protein synthesis, translating genetic information from mRNA into proteins.
  5. 10. The gel-like substance within the cell membrane, containing organelles and other cellular structures.
  6. 13. Membrane-bound sacs within the cytoplasm of plant and fungal cells, involved in storage, digestion, and waste removal.
  7. 15. Organelles found in plant cells, responsible for functions such as photosynthesis, storage, and pigment synthesis.
  8. 17. The central organelle of a eukaryotic cell, containing the cell's genetic material (DNA) and controlling cellular activities.
