Explore real-life examples of photosynthesis, biosynthesis, and cellular respiration in plants and organisms. Witness morning glory flowers opening, acorns growing into oak trees, and Venus fly traps catching prey. Understand how plants obtain nitrogen for protein synthesis and why plants react to environmental changes.

Lesson 5 Other Examples Practice explaining photosynthesis, biosynthesis and cellular respiration
The grass is covered with dew when you wake up in the morning to go to school. • Morning glories use energy to open their flowers in the morning and close their flowers at night. • An acorn is buried by a squirrel. The squirrel can’t find the acorn and it grows into an oak tree. After 10 years, the oak tree weighs more than 500 pounds. • Venus fly traps and pitcher plants grow in soil that has little to no nitrogen, but the plants have nitrogen in the proteins of their cells. Where do these plants get the nitrogen they need to build proteins? • A venus fly trap shuts quickly to catch a fly. • An airline company allows customers to pay for trees to be planted as a “carbon offset.” • 1 oz. of peanuts has more calories than 1 oz. of lettuce. • A plant from outside is moved into an office with no windows and the plant stops growing. • A seed sprouts very far under ground where there is no sunlight.
