Welcome To The Inventions Site!

In animals the haploid cells combine into a diploid zygote, which develops into a new diploid individual In algae and plants, however, it’s more complicated. The production of spores in green algae mostly occurs within individual cells, but in land plants, a small, diploid, multicellular body, technically a separate plant called a sporophyte, develops for that purpose. In the land plants we call vascular plants, however, sporophytes became larger and larger, and in fact the trees, herbs, and grasses we see today are actually the sporophyte generation of the plant life cycle. In the evolutionary story of sexual reproduction in plants, we find that the algae similar to those that gave rise to land plants, and simpler land plants themselves, are haploid and do produce sperm and egg directly. Understanding how plants and algae reproduce impacts both agriculture and ecology. Spores are adapted for long-distance dispersal, and germinate to form new haploid plants that will eventually produce gametes. Eventually the layers form a prototype which can be used for a vast array of things.

One of the things you learn in introductory biology or zoology, is that there are two basic symmetry patterns in animals: radial and bilateral. The alternate symmetry, bilateral, means that the animal has two sides that are mirror images, but only if the cut is made a certain way. Looking down on the top of such an organism, you can see that it could be cut in half at different angles and the two halves would always be essentially identical. In humans, if you make the (imaginary!) cut, it has to follow the spine exactly, cutting the head and torso into equal left and right halves. It is also a way to make sense of the fundamental features of plants, some of which may be dismissed as obscure and unimportant, but which are loaded with both meaning and utility. Yes, it’s complicated, but if the story unfolds from the perspective of how and why it evolved, it does make sense. Make a graph demonstrating their producer, elements, evaluating, where they are sold, who they appear to be focusing on, and where they are publicizing or advancing their items.

Nevertheless, you are going to want to make sure to protect yourself from getting your idea stolen and keeping your idea yours. Expand your original idea into new markets, find new uses, and add more features. During this project you will be choosing an invention and inventor that you find interesting and research the one you choose. Independent inventor Rodney Toole enlisted the help of InventionHome to assist him in finding marketing/licensing opportunities for his invention. InventionHome announces their Invention of the Week – “Extendable Hammer”. Legitimate patent invention services will never push you to file a patent as one of the first steps. It is worth mentioning that this is the world’s first display to have this feature. Movie company directors have been noticed employing solar lights throughout the filming of clips by means of the night. This reminds me of something which happened many years ago, a friend of mine Amy who works as a clerk in an advertising company.

Submission guidelines and agreements are created to represent a fair balance and protect your interests and those of the company that you’re submitting your idea to. Is your idea a one-time purchase? Students already sophisticated enough to know that sperm and egg in animals are produced through the special kind of nuclear division called meiosis are truly puzzled by why that does not happen in plants. Most familiar animals are built this way. In addition, some inventions are simply answers to medical problems, as in prosthetic devices while others are simply “improvements” made to existing inventions. While in 1815 there had been just one stove dealer in New York City (plus the Youles), by 1825 he was still in business and had been joined by eight others. Non-majors texts may be more appropriate for most of today’s audience, but they still tend to avoid a side of biology that I call the “why” questions. That is the “what,” at least in a simplistic sense, but there is typically no “why” to follow it.
