  THE SEED - STRUCTURE & GERMINATION What is a seed? A seed is a fertilized, matured ovule of a flowering plant, containing an embryo. This tiny embryo enclosed within the seed develops to form a new plant by the process of germination. Plant embryos in seeds have structures called cotyledons. A cotyledon is the central part of a seed embryo to which the plumule – the immature shoot, and the radicle – the immature roots, are attached. Seeds are classified according to the number of cotyledons present in the embryo. If the embryo has one cotyledon (monocotyledon) it is a monocot plant, and if there are two cotyledons (dicotyledon), it is a dicot plant. Example: Monocot seeds  – Maize, Wheat, etc.  Dicot seeds  – Pea, Gram, kidney Bean, etc. The structure of Dicot Seed: A bean (dicot) seed is normally kidney-shaped, flat, and has a notch on one side. Dicots have two seed leaves inside the seed coat. They are usually rounded and fat because they ...

                      The      Human      Circulatory      System Some Interesting  Facts: The circulatory system in the human body stretches 66,000 miles more than two and a half turns, the center of the Earth. The heart beats 2.5 billion times during the life of a 75-year-old. The heart expels 2 ounces of blood with each beat, 5 quarts of blood each minute, 220 million quarts in 70 years. If the red blood cells from one person were to be stacked in the sky, they would reach 31,000 miles Each red blood cell has 270,000,000 hemoglobin molecules; each hemoglobin molecule can carry four oxygen molecules. Blood flow measurement is vital because it provides a window into the delivery of oxygen and nutrients to body organs and cells.   Structure of Human Heart Location -   The heart  is the main pumping organ that pumps and also collects blood from the various parts of the ...
