Growth

• Growth is the increase in the size of an organism or its parts.
• Food provides the raw materials for growth
• Growth can be measured using line graphs and bar graphs
• Animals stop growing at maturity but plants continue to grow their whole lives
• In plants, growth is the addition of new parts ahead or around the other ones
• In animals, growth is diffused by all round increases of different organs around the body
• The gradient of a growth curve shows the rate of growth
• A straight line on a graph means that there has been no change over time
• A linear increase means that it's increasing steadily
• An exponential increase means that something is increasing very quickly
• A curved decrease means that it's decreasing slowly
