This week we studied plant structures and have been working on a project to record our learning. I will include the notes we collected as a class, as some students will need to finish the project for homework next week. This week we also studied compound sentences which we will continue next week, and we finished our study of theme. In math 4th graders studied how to solve two step word problems, while 5th graders studied multiplication and division of decimals.
Plant Structure notes
Roots secure the plant in the ground and store nutrients. Water and minerals move upward from the roots through the xylem to the rest of the plant.
Stems support leaves and and flowers, and transport water and minerals from the roots through the xylem, as well as transport food (glucose) from the leaves through the phloem to be stored in the roots
Leaf does the job of manufacturing food (glucose) by means of photosynthesis. The leave uses carbon dioxide, that it gathers through tiny holes called stomata, and water with energy from the sun to make sugars (glucose) that the plant uses as food. The leaf's cuticle protects it from water loss, while the chloroplast that contain green chlorophyll collects energy from the sun for photosynthesis.
Flowers are responsible for reproduction. The male parts of the flower, the stamen contains pollen which is gathered by pollinators like bees. The bees fly to a new plant and deposit the pollen on the pisitil of a new flower. The pollen falls down the tube into the ovary where the ovules (eggs) combine with the pollen to create a seed. The seed will turn into a new plant.
