Parts of a Plant Roots grow down into the soil and carry water to the plant. The stem holds the plant up and takes water to the leaves. A plant’s leaves help it by making food from sunlight. Flowers attract bees to pollinate and make new flowers. The pistil and the stamen work together to grow new plants.
What Plants Need to Grow – Air (CO2) – Sunlight to make food. – Water – Soil and nutrients
Plant Lifecycle From, the seed, roots grow down and the stem (sprout) grows up. Next, the stem and leaves grow. Later, flowers (buds) grow. The sepal protects the flower before it blooms. Once the flowers bloom, the stamen drops pollen on the pistil so that new seeds can grow. http://www.sln.org.uk/science/lifecycle/
Plant Problems Touch is harmful to plants. Skin oils turn petals brown. Gravity exerts force on the plant’s structure. Some bugs, like aphids and snails, eat leaves and stems, which kills plants.
Plant Solutions Scientists have developed solutions, like protective sprays. And aphid eating insects like ladybugs.
Challenge! As an extension activity, students may create a newsletter, slideshow, or publication. Also, students have the option of creating a “mutant plant” from different plant parts.
