Just like the human body, every part of a plant has a specific purpose to help it survive and flourish. While we may look at plants for the beauty of their flowers, every part is serving a purpose for the greater good. Children can understand how plants work by looking at all of their parts and learning what functions they perform.
Roots and Stems
Roots grow down into the earth to make sure a plant is properly anchored. They also take in water from the ground and help plants to get all the nutrients they need. Stems protrude from the base of the plant to hold the flowers and leaves. They work with the roots to make sure that water distributes evenly throughout the plant. The buds on the stems help create additional stems or leaves.
Seeds and Fruits
Seeds are small parts of a plant that are intended to come off and land elsewhere so that more plants can grow. Some plants have seeds that naturally do this, while others have seeds that are stored in fruit. People and animals frequently eat the fruit and seeds often find their way out of the fruit during the process. Fruits are often colourful and shapely to draw attention from any animal that passes them.
Flowers are not present on all plants, though when they are they exist to create more seeds so that more plants can grow. Much like fruit, flowers have features designed so that animals, birds and insects will be drawn to them. The goal of the flower is to draw these creatures in with its colours and smell so that they will pick up its pollen and spread it to other plants. Pollen spreading helps in the creation of new plants.
The leaves of the plant are the part that helps it grow and thrive. The leaves take in sunlight and water and undergo a process called photosynthesis to make these resources into energy. Leaves absorb sunlight while also collecting water when there is precipitation. Leaves also have pores that assist in taking in oxygen. Sunlight and water are the reason why leaves are able to turn green.
