BIOLOGY - Essay ExampleAn outer tissue layer which forms the outer covering of the organelle and cozy membrane which is twisted n folds to form specific structure called Cistae. There argon granules attached in the inner folds of cistae and the inside of a mitochondrial is filled with mitochondrial matrix. The main function of mitochondria is to produce energy for the cell in the form of ATP hence the name power house of the cell.Ans3. Centrifuge is process finished which we can obtain different cell organelles. The process works in a way that when a solution containing cells is centrifuged, the supernatant fluid containing our required cell organelles separates out on the surface which is then hive away and observed under the microscope to study required cell organelle.Ans4. Hemoglobin is present in red line of products cells and is a necessary component for living things to survive. Hemoglobins main function is transport of oxygen. When deoxygenated affinity goes by dint of t he lungs, the hemoglobin in RBCs attracts oxygen towards it. Oxygen binds with hemoglobin in the blood cells and is carried out to the form tissues where it is released from the hemoglobin and blood once again goes to lungs for oxygenation.Ans5. The main mechanisms of transport through cell membrane are 1) Diffusion 2) Active transport and 3) passive transport. Diffusion is the simple moving of molecules through the cell membrane across a niggardness gradient. Active transport occurs when a molecule is supposed to be transported against the concentration gradient. Active transport takes place with the help of specific carriers that carry our required molecules against the concentration gradient through specific channels and this process requires energy. Passive transport occurs when a molecules uses another channel to move across the cell membrane.Ans7. DNA consists of two ribose sugar strands which are joined by nucleic acids Adenine, Guanine, Cytosine, Thymine. These bases form the inner
