Student Blog Post Assignment #6: How Does Your Garden
1. How is your plant (or any plants in our garden, for that matter) getting bigger and adding biomass? Your explanation should be correctly use the terms and concepts of cell division (mitosis), photosynthesis, and cellular respiration.
Answer For Question 1: Our broccoli (and many other plants in the garden) have grown to it’s possible full limit. Given with their survival materials, energy, which is provided by the plants energy by the suns heat, sunlights by the sun (making photosynthesis converted by light energy) , rain, and soil from the grass giving the cells in the ground that give the plant the healthy needs they need. In fact, with growth in cells, they increase growth by mitosis. This way, plants can increase their current size. Mitosis has about 7 stages in growth. Interphase is the first stage. Which cells obtain nutrients and metabolizes them. Prophase in the 2nd stage, where the nucleolus disappears. Prometaphase separates the duplicated genetic material carried within the nucleus. In Metaphase, each chromatid faces opposite pole. Anaphase, which is the next step, breaks at centromeres, and sister chromatic move to opposite ends of the cell. Telephone is where the poles are becoming more diffuse and the nuclear starts to reform. The last stage is known as cytokinesis where the mitosis ends with the cell nucleus being divided and the cytokinesis starts to kick in.
Our broccoli grows within its cells, cellular respiration is also involved in this. Cellular respiration has 3 major steps, 1 Glycolysis. Glycolysis gets converted into pyruvate with a little bit of using ATP energy involved. The second step is called, Krebs Cycle. The pyruvate from the first step also gets converted getting oxidized carbon dioxide, 2 ATP molecules, 6 NADH molecules and 2 FADH2 molecules ( which helps make even more ATP energy) The last step is Electron Transport Chain. Basically where electrons get transferred in carriers (which is practically the chains) The proton helps power the ATP synthase that makes ATP with using oxygen. Every plant in the garden makes ATP, even if there’s no oxygen produced.
2. Phosphoglycerate kinase (PKG) and ribulose 1,5-bisphosphate carboxylase/oxygenase (Rubisco) are two important enzymes used in photosynthesis. Describe how plants in the garden would make enzymes like these if a signal was sent to the nucleus to produce more of one of them. (Hint: enzymes belong to which category of biomolecule?)
Answer For Question 2: To start off, plants can communicate with each other by protein receptors on the surface of the plasma membrane. Phosphoglycerate kinase is an enzyme that catalyzes the reversible transfer of a phosphoglycerate and ATP. Ribulose- 1, 5 bisphosphate is also a organic substance. It’s also a enzyme. In the Calvin cycle in the photosynthetic organisms, PGK catalyzes the phosphorylation of 3 PG, producing 1, 3-BPG and ADP, as part of the reactions that regenerate ribulose-1,5- bisphospahte. When giv gets out signals, cells typically signal molecule joins with a appropriate receptor on a cell surface. The category that the biomeclue belongs in is proteins. They are distinct from carbohydrates, nucleic acid and lipids.
