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
