Adaptive Features

Muhtasari

A cactus storing water in a fat green stem, a water lily with leaves that float, every species carries inherited features that fit it to its surroundings. These adaptive features are the visible result of natural selection, and learning to read them lets you explain how an organism survives where it lives.

In this lesson you will define an adaptive feature, practise describing the adaptations of a species from a picture or description, and (for Extended) explain in detail how xerophytes are adapted to dry conditions and hydrophytes to life in water.

Malengo

  1. Describe an adaptive feature as an inherited feature that helps an organism to survive and reproduce in its environment
  2. Interpret images or other information about a species to describe its adaptive features
  3. [Supplement] Explain the adaptive features of hydrophytes and xerophytes to their environments

Maelezo ya Somo

Adaptive features connect structure to survival and lead directly into natural selection and evolution. Exam questions often show an unfamiliar organism and ask you to pick out its adaptations and say how each helps, a skill, not a memory test, so the reasoning here is what earns marks.
