Starch is made up of long chains of glucose, which is a simple sugar. Starch can either be simple linear lines of glucose, like amylose, or it can be a complex molecule with glucose branching off the chain, like amylopectin.
Starch is found in nature in plants. Glucose that is produced by photosynthesis and is not needed right away is stored as starch. Different plants store the starch in different organelles. For example, starch is heavily stored in tubers that people eat from potato plants. If the plant requires energy, it breaks down the starch back into glucose. Similarly, humans can eat starchy fruits and flowers for energy, as the starch can be broken down into glucose.Learn More
GMOs, or genetically modified organisms, are made by cutting a desired gene from one organism and inserting the new DNA into the cells of another organism. The organism with the new gene is then bred to produce offspring that can pass down the new gene.Full Answer >
A plant cell wall is made of cellulose, which is a complex sugar. The cell walls both protect and provide shape and structure for plants' cells, allowing some to reach great heights.Full Answer >
Seeds are made within the ovaries of some species of plants. Not all plants have the ability to produce seeds. Only those in the divisions Cycadophyta, Ginkgophyta, Gnetophyta, Coniferophyta and Anthophyta use seeds for reproduction. They are generated from the ovule of the mother plant and the pollen grain of the father plant.Full Answer >
