2.1.1 (d) Biological drawings

How should label lines on a scientific drawing be drawn?  

• With a ruler. 

• In pencil or pen. 

• With an arrow head just touching the feature. 

• With a straight line to the middle of the feature.

How should a scientific drawing be placed on the page?

• Right in the corner, so no paper is wasted.

• In the middle of the page, to allow for annotations around it.

• Covering at least 50% of the space.

• Covering at least 25% of the space to allow for more annotations.

Which of these is a good heading?

• Diagram of a cell.

• TS of a root cell.

• Diagram of a root cell from Helianthus annus.

• TS of a root cell from Helianthus annus.

Parts of the cell that are observed to be darker, should be shaded or coloured in to show a true representation of the image.

• True

• False

Which of these is a good annotation for a scientific drawing?

• Chloroplast.

• Chloroplast, containing chlorophyll to carry out PS.

• Chloroplast, containing chlorophyll to carry out photosynthesis.

• A chloroplast is a type of membrane-bound organelle known as a plastid that conducts photosynthesis mostly in plant and algal cells. The photosynthetic pigment chlorophyll captures the energy from sunlight, converts it, and stores it in the energy-storage molecules ATP and NADPH while freeing oxygen from water in the cells. The ATP and NADPH is then used to make organic molecules from carbon dioxide in a process known as the Calvin cycle. Chloroplasts carry out a number of other functions, including fatty acid synthesis, amino acid synthesis, and the immune response in plants.
