Introduction Good Morning Everyone. My name is and this is ‚ and . We will be presenting to you on how Light affects gene expression with focus on Maize leaves. This is an unrelated but neat photo of gem corn which is produced as a result of selective breeding. Anyways‚ most plants require light in order to grow and conduct photosynthesis. Plants that have been previously grown in the dark are incapable of photosynthesis since they lack chlorophyll and many polypeptides needed for light harvesting

An Introduction to Peroxisomes: “Peroxisomal Proteins and Pathways in Drosophila” Discovered in the 1950’s‚ peroxisomes were found floating within a cell’s cytoplasm using electronic microscopy by J. Rhodin (Schluter‚ 2010). These were later classified as organelles and the functions of these organelles were also further discovered and understood. Peroxisomes are membrane-bound organelle that are found in all eukaryotic cells participate in many metabolic reactions within the cell. These reactions

capable of functioning independently. Chemiosmosis- The process by which ATP is produced in the inner membrane of a mitochondrion. The electron transport system transfers protons from the inner compartment to the outer; as the protons flow back to the inner compartment‚ the energy of their movement is used to add phosphate to ADP‚ forming ATP. chloroplasts - Disk-like organelles with a double membrane found in eukaryotic plant cells; contain thylakoids and are the site of photosynthesis. ATP is generated

1.) What is Biology? Biology is the science of life. Biologists study the structure‚ function‚ growth‚ origin‚ evolution and distribution of living organisms. There are generally considered to be at least nine “umbrella” fields of biology‚ each of which consists of multiple subfields. 2.) What are the branches of Biology? Describe each. Biochemistry: the study of the material substances that make up living things Botany: the study of plants‚ including agriculture Cellular biology: the study of the

Planning Aim In this experiment I will be testing the effect of temperature on the plasma membrane of a beetroot. I will do this by measuring the percentage light transmission using a spectrophotometer. Once I have obtained my results‚ I will justify them using scientific knowledge explaining what I have observed whilst carrying out the experiment. Factors to be controlled "« The pH concentration "« Regular use of distilled water "« Ensuring that the surface area of each piece of beetroot is
