Deb is studying the difference between 2 types of soil. She notices that her plants grow more when they have additional nitrogen
Dennis_Churaev [7]

The molecule, which the plant is most likely synthesizing using the extra nitrogen is PROTEIN.

Plants and animals do not have the capacity to use atmospheric nitrogen as nutrient. Atmospheric nitrogen has to be converted to forms that are usable by plants and animals before they can utilize it. Nitrogen fixing bacteria are the ones that are responsible for converting atmospheric nitrogen to the forms such as nitrate and ammonium, which can be used by plants. Animals get their own portion of nitrogen when they eat plants or other animals. Nitrate is the form of nitrogen that is mostly used by plants. Excess ammonium in plants are usually used directly to synthesize proteins. Nitrogen is a very important component of chlorophyll, which is essential for photosynthesis. Nitrogen is also found in the genetic materials of plants and it is needed for their growth and development.  Animals used nitrogen to synthesize proteins, nucleic acid and other biological compounds that contain nitrogen.

  • A plate, often described as a lithospheric plate, with seafloor, continents and mountains on top of it.
  • The earth is divided into three layers based on their chemical composition. Undoubtedly, there is a component called the lithosphere.
  • The lithosphere consists of a crust and a portion of a solid upper mantle.
  • Below the lithosphere is the asthenosphere.
  • There are two types of crusts: the continental crust and the oceanic crust.
  • Where there is a seabed there is a sea crust.
  • Mountains are also found in oceanic and continental crusts.
  • The intercontinental layer corresponds to the continents.

Which process must occur before the gametophyte generation?
Ber [7]
<span>The process must occur before the gametophyte generation is Sporophyte. A sporophyte is the diploid generation of a plant or alga that has a double set of chromosomes. [ All land plants, and some algae, have life cycles in which a multicellular haploid gametophyte generation alternates with a multicellular diploid generation. In the Gymnosperms and flowering plants (Angiosperms), the sporophyte generation is the most prominent phase, comprising the familiar green plant with its roots, stem, leaves and cones or flowers. In the flowering plants, the gametophytes are very reduced in size, and are represented by the pollen and the embryo sac.</span>
