In this video, Dave Horak will explain plant evolution and adaptations. All plants have similar structure and needs. Then why are there different types of plants? Why do they grow in different places? The one-word answer is evolution — a natural process that has shaped all living things. Plants pass their features to their offspring and sometimes small variations called mutations change these characteristics. These changes may improve the plant’s chance of surviving in its environment by providing defense mechanism against predators, helping in getting food and nutrition, or facilitating reproduction. These changes are identified by paleobotanists, scientists who study plant fossils to understand how they evolved overtime.
This video satisfies the 4-LS1-1 requirement of fourth-grade science proficiency.
Students who demonstrate understanding can: 4-LS1-1 Construct an argument that plants and animals have internal and external structures that function to support survival, growth, behavior and reproduction.
