The three parts of a seed are the embryo, the endosperm and the seed coat. The reproductive parts of the flower that are necessary for seed production are the stamen (the male organ) and carpel (the female organ). Start studying Parts of a Plant cell & their functions (5th Grade). The plants are composed of a series of areas and underground structures. Flowers. The main functions of the root system are absorption of water and minerals from the soil, providing a proper anchorage to the plant parts, storing reserve food material and synthesis of plant growth regulators. They need food and sunlight to grow. The embryo is a miniature form of the plant that is fed by the nutrition contained in the endosperm. Plants grow everywhere. Sexual reproductive parts produce seed; they include flower buds, flowers, fruit and seeds. Learn to correlate the parts with their functions. Every plant is made up of four essential parts that scientifically classify it as a plant. Seed Science Experiments. THE ROOT SYSTEM – It is located below the ground, responsible for absorbing water and minerals from the soil as well as give firmness to the whole plant/tree. Aerial structures are those that grow above the Earth's surface, such as stem , leaves, flowers and fruits. Seed coat, micropyle, endosperm and embryo are major parts of a seed. List of parts of the plant with their functions . Perfect vs. Imperfect. Let’s know about the parts of a plant. Each of these four parts plays an important role in helping the plant to grow and thrive. If a flower has both of these parts, it is called a perfect flower, even if it lacks some of the other key parts. The embryo is protected from the external environment by the seed coat. These easy seed science experiments are a great way for 1st, 2nd, and 3rd grade students to explore the parts of a seed and learn their functions as they dissect and label the inside of a seed. Sexual reproduction is the sole function of flowers, often the showiest part of a plant. Flowers' beauty and fragrance evolved not to please humans but to attract pollinators (insects or birds), which are central to the reproductive process. The Root.
