Life Cycles of Plants and Animals
The life cycle of plants and animals refers to the series of changes and stages that an organism goes through from birth to reproduction and eventually death. Understanding life cycles is important as it helps us comprehend the growth and development of living organisms.
Life Cycle of Plants
Plants have a life cycle that includes several stages:
- Seed Stage: The cycle begins with a seed, which contains the genetic material needed for a new plant.
- Germination: The seed absorbs water and begins to sprout, developing into a seedling.
- Growth: The seedling grows into a mature plant, producing leaves, stems, and roots.
- Reproduction: The mature plant produces flowers, which contain reproductive organs. Pollination occurs, leading to the formation of seeds.
- Seed Dispersal: The seeds are released and dispersed, beginning the cycle anew.
Life Cycle of Animals
Animals have diverse life cycles, but they generally include the following stages:
- Birth or Hatching: Animals are born or hatch from eggs, beginning their life cycle.
- Growth and Development: Young animals grow and develop, often going through various stages such as larvae, pupae, or molting as they reach adulthood.
- Reproduction: Adult animals reach sexual maturity and reproduce, continuing the cycle by producing offspring.
- Aging and Death: As animals age, they may experience decline in health and eventually pass away, completing the life cycle.
Study Guide
To study life cycles of plants and animals, consider the following points:
- What are the stages in the life cycle of a plant?
- How does germination occur in plants?
- What are the different stages in the life cycle of animals?
- How do plants and animals ensure the continuation of their species through reproduction?
- What are the similarities and differences in the life cycles of plants and animals?
By understanding the life cycles of plants and animals, we gain insight into the intricate and fascinating processes of growth, reproduction, and renewal in the natural world.

LIFE SCIENCE
From Molecules to Organisms: Structures and Processes
Create representations to explain the unique and diverse life cycles of organisms other than humans (e.g., flowering plants, frogs, butterflies), including commonalities such as birth, growth, reproduction, and death.
Unity and Diversity
Construct an argument from evidence to explain the likelihood of an organism’s ability to survive when compared to the resources in a certain habitat (e.g., freshwater organisms survive well, less well, or not at all in saltwater; desert organisms survive well, less well, or not at all in woodlands).
Create models that illustrate how organisms and their habitats make up a system in which the parts depend on each other.
