Student notebooks, particularly the answers to the student's six questions, will also be used to assess student growth in understanding. Plants use special structures to help solve the problems of survival. Most living things must obtain nutrients, water, and oxygen. They also require an appropriate place to live. Living things must solve problems, develop adaptations, to meet their needs.
Adaptations allow organisms to succeed.
Plants must be able to withstand forces in their environment. Roots keep plants attached to their habitat. Stems withstand forces of wind, water, gravity, and animals that could uproot or break them. The structure of leaves may show adaptations to resist destructive forces. Plants have special structures for obtaining water and nutrients, distributing them to all tissues, and using these materials to efficiently produce food.
