  1. Cells Click to start

  2. A Cell membrane B Ribosomes C chloroplasts Mitochondria D Question 1 What is found only in plant cells?

  3. Wrong Answer! Chloroplasts contain chlorophyll, the green pigment needed for photosynthesis Try Again

  4. A Cytoplasm B chloroplasts C Nucleus Endoplasmic reticulum D Question 2 Where do most cellular reactions take place?

  5. Wrong Answer! Most cellular reactions occur in the cytoplasm, some occur in the membranes of organelles e.g.mitochondria Try Again

  6. A Nucleus B Cytoplasm C Ribosomes Mitochondria D Question 3 Where does respiration occur?

  7. Wrong Answer! Mitochondria are the organelles responsible for respiration. Respiration PRODUCES energy Try Again

  8. A Mitochondria B Chloroplasts C Ribosomes ATP D Question 4 If a cell was responsible for making enzymes, which are …………, which organelle would the cell contain a lot of?

  9. Wrong Answer! Enzymes are proteins. The Ribosomes are involved in protein synthesis and the Endoplasmic reticulum packages the proteins. Try Again

  10. A Nucleus B Plasmid C DNA is usually circular Cell wall made of peptidoglycan D Question 5 What feature is not found in a bacterial cell?

  11. Wrong Answer! The long strand of DNA (the bacterial chromosome) is usually circular and found free in the cytoplasm. Bacterial cells do not have a nucleus Try Again

  12. A Identification used for Ella B Strands of carbohydrate C Bacterial identification Protein strands involved in movement D Question 6 What are flagella?

  13. Wrong Answer! Flagellum (pleural flagella) are long protein strands that lash about and are used to move bacteria. Try Again

  14. A Oxygen B Carbon dioxide C Glucose Water D Question 7 Yeast cells are another single–celled microorganism, which under aerobic conditions produce ………., used to make bread rise?

  15. Wrong Answer! Yeast can respire aerobically, with oxygen to break down glucose into carbon dioxide and water, CO2 is used to make bread rise Try Again

  16. A Methanol B Ethene C Ethanol Vodka D Question 8 Yeast respires anaerobically to produce alcohol, that is correctly called?

  17. Wrong Answer! Fermentation (anaerobic respiration) breaks down sugar to produce ETHANOL and carbon dioxide Try Again

  18. A Large Surface Area B Close to the Xylem vessels C Large permanent vacuole Has a cellulose cell wall D Question 9 Cells become specialised in order to carry out particular jobs, which statement is FALSE about how the root hair cell is specialised to absorb water and minerals?

  19. Wrong Answer! All plant cells have a cell wall, this is not a feature which helps the root hair cell absorb water Try Again

  20. A Organ B Tissue C System Organ system D Question 10 A group of cells with similar structure and function is called a ………?

  21. Wrong Answer! There are different types of tissue, muscular tissue can contract and bring about movement, glandular tissue contains secretory cells that can produce enzymes and hormones, epithelial tissue covers the outside of the body as well as your internal organs Try Again

  22. Congratulations! • Well done 10 set 2!
