Week 2 – SC.F.1.2.3Benchmark: The student knows that living
things are different but share similar structures.
Essential Question:How are living things alike and
different?

Parts of a Plant Basic Plant Needs Water Soil Sunlight Space to grow Air
PhotosynthesisPlants use energy from the sun to make their own food.
Plants have leaves, stem, roots.Plants reproduce with seeds (flowers, cones, fruits) or
spores. Plants Are Living Things
