6. The intracellular structures are collectively called

  • Organelles
  • Vacuoles
  • Particles
  • Inclusions

7. A structure in the cell which is responsible for the destruction of old or redundant cell components is called

  • The lysosome
  • The ribosome
  • The Vacuole
  • The Golgi apparatus

8. Cell components that are responsible for the sculpting or removal of redundant tissues are called

  • Lysosomes
  • Golgi Bodies
  • Ribosomes
  • Endoplasmic reticula

9. The DNA of a cell instructs the protein synthesis apparatus by

  • Duplicating itself and sending the second copy to the sites of protein synthesis
  • Leaving the nucleus
  • Replicating to produce a smaller single strand molecule called messenger RNA, for the purpose of delivering instructions for protein synthesis
  • Replicating to produce larger molecule for the purpose of protein synthesis

10. Endocytosis

  • A mechanism for cell division
  • A method of excretion for old cell components and waste material
  • Is a multistage mechanism that requires metabolic energy for bringing materials into the cell
  • An internal mechanism for cell movement

11. Cells divide to make more of themselves for both tissue growth and cell replacement purposes. The process is called…

  • Micelle formation
  • Meiosis
  • Mitosis
  • Mycosis

12. The instruction centre for the cell’s activities is

  • The nucleus
  • The lysosome
  • The ribosome
  • The endoplasmic reticulum

13. Cilia are

  • Cells with an extra long process (like a tail) used for movement of the cell in an aqueous environment
  • Cytoplasmic outgrowths that are made of hair they waft particles or fluids along channels
  • Cytoplasmic outgrowths that resemble hairs, they have rhythmic motion designed to waft particles or fluids along channels
  • Cytoplasmic outgrowths that absorb substances in the gut

14. Facilitative diffusion

  • Works in the same way as simple diffusion but with the inclusion of special carrier proteins in the cell membrane without the need for ATP
  • The passive movement ions across excitable membranes
  • Uses ATP
  • The stepwise multistage mechanism for bringing materials into the cell that requires metabolic energy

15. The mitochondria has its own

  • DNA, endoplasmic reticula
  • DNA and Golgi bodies
  • DNA, RNA and ribosomes
  • DNA, RNA and lysosomes

16. The cell moves by use of

  • The cytoskeleton shifts its components from one area of the cell to another creating consistency changes in the cytoplasm
  • The cell uses phospholipid to swim in aqueous surroundings
  • The cell surface glycoproteins change shape to facilitate cell movement
  • The cell cannot move

17. The lipids of the cell membrane

  • Help stabilise the membrane
  • Are hydrophobic (hate water)
  • Are hydrophilic (like water)
  • Act as cell surface identity markers

18. The nucleus contains all but

  • Chromatin (DNA/RNA and their building blocks)
  • Nucleoli
  • Mitochondria
  • Nucleoplasm

19. Cells have

  • A programmed life span
  • A and B are correct (A programmed life span & Die when they are starved of nutrients and or oxygen)
  • Die when they are starved of nutrients and or oxygen
  • Cannot die

20. The Rough Endoplasmic Reticulum

  • A series of channels that prepare cholesterol molecules for the formation of steroids
  • A series of cytoplasmic transport channels dotted with lysosomes
  • A series of cytoplasmic transport channels dotted with ribosomes
  • A series of cytoplasmic folds used to complete the formation of peptides
