An electron micrograph of a tissue specimen is markedly different to the image of the same material as seen under a light microscope, because it

• is black and white in colour and significantly magnified to display fine organelle detail.

• allows the identification of cellular organelles based on their chemical composition and differing reaction with the many stains used.

• is produced through the use of specially designed prisms to split and recombine light to produce detailed images.

• shows metabolic activity within cells even following staining.

What is a similarity between aerobic and anaerobic respiration

• The location

• The type of energy produced

• Waste product produced

• Requirement of oxygen

A brown-coloured plant found in a dry eucalyptus forest was classified by a biologist as a photosynthetic autotroph. Which of the following statements about the organism must be correct?

• The plant must have been growing on the branches of another living tree.

• The plant must have been using organic matter from the soil in which it was growing.

• The plant must have been converting solar energy into chemical energy.

• The plant must have been using energy obtained from the inorganic substances it had absorbed.

What is the correct order in which organelles function to make and secrete an enzyme?

• nucleolus → lysosome → Golgi body → vesicle

• nucleolus → smooth endoplasmic reticulum → lysosome → vesicle

• nucleus → rough endoplasmic reticulum → Golgi body → vesicle

• nucleus → smooth endoplasmic reticulum → lysosome → vesicle.
