Explain how we can plot a graph.
✓
Answer
To plot a graph on a graph sheet:Take a graph paper. At the centre of the paper, draw two lines perpendicular to each other Mark the point of intersection of the lines as $'O'$. The horizontal line is called the $X$-axis, while the vertical line is called the $Y$-axis. The point of intersection of the two axes is called the origin, $"O"$. Take one quantity along the $X$-axis and the other along the $Y$-axis, after choosing suitable scales for both. For every value along one axis, mark a point matching the related value on the other axis. Join the points, and your graph is ready.

Oxygen which is essential for the survival of all organisms is produced during photosynthesis. In the absence of photosynthesis, life would be impossible on the earth. During photosynthesis, chlorophyll containing cells of leaves, in the presence of sunlight, use carbon dioxide and water to synthesise carbohydrates. During the process oxygen is released. The presence of starch in leaves indicates the occurrence of photosynthesis. Starch is also a carbohydrate.
