Plant Structure and Function: Plant Groupings

The video tutorial explains the classification of flowering plants into three main groups: annuals, biennials, and perennials. Annuals complete their lifecycle in one year, biennials take two years, and perennials live for many years. Examples of each type are provided, such as marigolds and petunias for annuals, cabbage and Holly Hock for biennials, and trees and shrubs for perennials.

Give examples of common annual plants mentioned in the text.

How do perennials differ from annuals and biennials in terms of lifespan?
