Plant Life Cycle

Plant Life Cycle

TEKS Objective

The student is expected to observe changes that are part of a simple life cycle of a plant: seed, seedling, plant, flower, and fruit.

Essential Understanding

The student knows that organisms resemble their parents and have structures and processes that help them survive within their environments.

Science Background

Life Cycle: University of Illinois, The Great Plant Escape (website) – Learn about plant parts and the life cycle of flowering plants.

Signature Lesson

Plants Change During Their Life Cycle: Lady Bird Johnson Wildflower Center (PDF) - Use Lesson 1 (pages 2–4) to observe changes that are part of the life cycle of a flowering plant.

Supporting Lessons

Plants Matters – Seeds, Fruit, and Trees: (website) - Trees start their life cycle as a seed. When they mature they produce their own seeds.  Match the seed to the adult tree in this activity.

Elaboration Lessons and Extensions

Tree Lifecycle: Project Learning Tree (PDF) – Students discover that trees have lifecycles similar to those of other living things.

Assessment Ideas

Plant Life Cycle Flash Cards: (website) – Print one or more sets of these plant life cycle cards, and have your students arrange the cards from “soil” to “plant” to assess their understanding of the stages of a simple plant life cycle.
