How does your garden grow

Our plant is growing bigger everyday thanks to cell division and photosynthesis.  Our plant uses the energy it gets from photosynthesis to divide its cells using mitosis.  The enzymes important in photosynthesis are, Phosphoenolpyruvate carboxylase and ribulose 1,5-bisphosphate carboxylase/oxygenase.  Say the plant doesn't have enough of these enzymes to live successfully.  First the DNA would be read and copied by a helicase.  The new strand of RNA will find a ribosome that will read it.  The ribosome reads the codon which tell it exactly what amino acids to connect to each other.  This strand of new amino acids can be anything but in this case they are the enzymes we need for photosynthesis.

                1. Photosynthesis is the process in which a plant uses sunlight to convert carbon dioxide and water into oxygen, which is released, and carbohydrates such as glucose which are used to store chemical energy. Cellular respiration then uses this stored energy to form ATP, and also releases waste products. This ATP is then used to drive several important chemical reactions, including those used to facilitate cell division. Mitosis is what actually creates new biomass to add to the structure of the plant.

                2. When a signal is sent to the nucleus to produce PEPC and RuBisCo, the cell would first transcribe the gene into mRNA with an RNA polymerase. The RNA polymerase bonds to the DNA strand, unravels it, and makes a complementary copy of one of the DNA strands into an RNA strand. The strand of mRNA finds a ribosome, which reads the first codon of the strand and finds the correct amino acid. It then moves on to the next codon and finds the next amino acid, stringing it to the first one. When it reaches the stop codon, the chain breaks off, and the enzyme, in this case PEPC or RuBisCo, breaks off and goes into the cell.

Our plant has gotten bigger thanks to mitosis, photosynthesis, and respiration. The plant receives the energy it needs from photosynthesis. This energy comes from the sun and glucose is eventually created. The energy created by photosynthesis is then used to start the cell division where the cells divide into new daughter cells. This process is known as mitosis. This will add biomass as the cells will be creating more duplicates and adding to the original form of the plant. Respiration is where the energy is released from photosynthesis.


Phosphoenolpyruvate carboxylase (PEPC) and ribulose 1,5-bisphosphate carboxylase/oxygenase (Rubisco) would be produced a lot for photosynthesis. These enzymes are categorized as proteins. The information for their creation is in the DNA. First the DNA is unzipped, a complementary copy is made, and then the ribosomes set off to work to look at the codons and add the correct amino acids. Then when the stop is reached,  the enzyme is sent off to start work.

  1.     Plant cells derive from divisions in the meristems of developing organs. However, plant cells are enclosed in rigid cell walls, unable to migrate and change their location within tissues. Thus, positions of division planes, together with successive polarised cell expansion are the major determinants of cell shape and consequently morphology of plants.CO2 is acquired from the atmosphere and converted into organic compounds in the process of photosynthesisSoil respiration is a key ecosystem process that releases carbon from the soil in the form of CO2.Soil respiration rates can be largely affected by human activity. This is because humans have the ability to and have been changing the various controlling factors of soil respiration. With that, even a 10% enhancement in relative growth rate can translate into absolute growth enhancements of up to 50% during the exponential growth phase of plants. When space constraints and self-shading force an end to exponential growth.
  2.    The first enzyme the cycle, fixing carbon to to ribulose. Its importance and relative inefficiency, up to 40% of all protein in plant cells is RuBISCOThe rate of photosynthesis is usually limited not by light but by the availability of carbon dioxide for fixation by Rubisco. Our plant can make create more enzymes like this by the DNA reading and coping one helicase.  The new strand of RNA will find a ribosome that will read it.  The ribosome then reads the codon which tell it exactly what amino acids to connect to each other.
