BUILD Understanding
Compare/Contrast Table Use a compare/contrast table when you want to see the
similarities and differences between two or more objects or processes.
As you read Lesson 4, use a compare/contrast table to investigate three ways angiosperms
are categorized. Use the terms in the box below to complete the first two rows of the chart. Then,
write three examples of each type of angiosperm.
stem characteristics
life span of one year
life span of two years
life span of many years
woody stems
smooth stems
number of growing seasons
