ii. What type of plant produces fruit?
iii. What part of the angiosperm becomes fruit?
iv. All the fruit that is consumed was produces by some type of angiosperm?
v. Why don’t gymnosperms and angiosperms need water to reproduce?
vi. Angiosperms have become the most diverse phyla of plants, and so botanists have
developed ways of classifying them
