  1. 2. is a type of cell which doesn’t contain a true nucleus or membrane-bound organelles and has “free floating” DNA.
  2. 8. is composed of microtubules and protein filaments that is found throughout the inside of a eukaryotic cell to maintain the cell’s shape, movement as well as cell division.
  3. 11. is a small set of microtubules (organelles) located in the cytoplasm of most animal cells near the nuclear envelope.
  4. 13. is the jellylike material that takes up most of the space inside the cell containing organelles and surrounds the nucleus.
  5. 15. different, small membrane-bound organelles that help move materials, such as proteins and other molecules, from one part of a cell to another (intracellular transport).
  6. 16. is a membrane-bound cell organelle that contains digestive enzymes that break down excess or worn-out cell parts and are used to destroy invading viruses/ bacteria.
  7. 17. (membranes shaped like pancakes) a type of organelle that is found inside the cells, which functions to package up proteins and transfer them to different parts of the cell.
  8. 18. is a type of cell that contains membrane-bound organelles like mitochondria, an endoplasmic reticulum, and possesses a (true) clearly defined nucleus.
  9. 19. is found in all cells and separates the inside of the cell from the outside and it regulates the transport of materials entering and exiting the cell.

  1. 1. is a subcellular structure that performs one or more specific jobs in the cell which works together with other structures to carry out important functions.
  2. 3. is a structural layer surrounding some cells, providing both structural support and protection, outside the cell membrane which can be tough and flexible.
  3. 4. refers to the cell membrane’s ability to differentiate between different types of molecules, allowing some molecules through while blocking others to pass in and out of the cell.
  4. 5. is also known as the powerhouse of the cell making energy (ATP) of the cell by taking nutrients, breaking them down, and creating energy rich molecules for the cell.
  5. 6. is a sphere-shaped structure within the cytoplasm of a cell that provides protein in the site of protein synthesis for the cell.
  6. 7. is a space within the cytoplasm of a cell, enclosed by a membrane and contains fluid/liquid for the cell which helps to maintain water balance.
  7. 8. theory contain 3 important points indicating that living things are composed of one or more cells, that the cell is the basic unit of life and that cells come from existing cells
  8. 9. is the center part (mind of the entire cell) of the cell with an important role to control the regulations and the activities of the cell of DNA and information.
  9. 10. are proteins inside a cell or on its surface, which receive a signal by receiving extracellular molecules and the membrane proteins that allow communication between the cell and extracellular space.
  10. 12. is a network of membranes inside a cell in which proteins and other molecules move and designed to synthesize enzymes for respiration.
  11. 14. is a type of lipid (fatty acids compound) molecule that is the main component of the cell membrane, which acts as a barrier to the passage of molecules in and out of the cell.
