Lipid Synthesis

The Smooth endoplasmic reticulum helps aid in the process of lipid synthesis. Smooth endoplasmic reticulum is found in a variety of cell types (both animal and plant), and it has different functions in both of the different cells. The smooth ER also contains enzymes that create glucose. 
The reason rough endoplasmic reticulum is called 'rough' are the ribosomes. Millions of ribosomes cover the surface of rough endoplasmic reticulum and make it appear bumpy under microscopic magnification. Ribosomes are the sites where proteins are created from amino acids.
The information for the synthesis of a particular protein, is conveyed from the DNA to the ribosome, by the messenger RNA (mRNA) mechanism. Rough endoplasmic reticulum is connected with the outer envelope of the cell nucleus. As described before, it is one of the largest cell organelles and is prominently branched out around the cell nucleus and Golgi bodies. 

CHLOROPLAST

The chloroplast is only found in plant cells. The chloroplast contains chlorophyll which is the ingredient needed to capture the solar energy required for photosynthesis.
The process of photosynthesis looks like this: 6CO2+6H2O+light ----> C6H12O6+6O2 and here is a picture to give you a visual. In the process of photosynthesis the energy from the sun (solar energy) is converted into chemical energy. The chemical energy is stored in the form of glucose which is then converted into ATP.
Here is a picture to show you photosynthesis:

The Mitochondria: Powerhouse of the cell. The mitochondrion has a double bound membrane found in the cytoplasm of eukaryotic and prokaryotic cells and it contains DNA. The Mitochondrion is the site of cellular respiration.
Cellular respiration is the set of the metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products. It happens through the process of photosynthesis and then goes through a chemical reaction to produce ATP.
Formula: C6H12O6 + 6O2 = 6CO2 + 6H2O + 36ATP

Mark Explanation

My mark is 56.4% and obviously I am not happy at all. I have this mark because I have not been completing my work and when I do complete it, it is not completed to my full potential. What I can do to increase my mark is finish all my work, study for tests and work hard to reach my goal to achieve a final mark of a B. From now on I will work hard, do all my assigned tasks and complete the work I have not handed in yet.
