How to draw Mitochondria Mitochondria is cell organelle which generates power required for cell and hence called `Power house of the cell". They are sac like structures present in the cytoplasm of the cells. They may be of various shapes like thread, spherical or club. Mitochondria have two compartments an inner compartment and an outer compartment. The viscous substance in the inner compartment is called Matrix. The matrix is surrounded by a membrane called Inner membrane. The inner membrane is thrown into several folds called Cristae. Now let`s draw mitochondria. Step 1: Draw a rough sausage shape with free hand in faint curve. Do not stop the curve in the middle, continue until you meet the starting point. Step 2: To give a sliced sausage look, draw one more curve as shown. Line inner side with another faint curve as shown. Step 3: Erase the inner line leaving the faint impression and mark the posit...
Plant cells are covered by cell wall, it is a unique feature observed in plant cells. While the cell membrane acts as the outer layer in animal cells. The plant`s cell wall is made up of Cellulose.This is considered as major difference between plant cell and an animal cell. The green parts of plants such as leaves, have cells which contain chloroplasts. Which is considered as another unique feature of plant cells. Let`s see how to draw a typical plant cell.

How to draw Bacteria Prokaryotes are the organisms which have primitive nucleus. All bacteria are prokaryotes because they lack a distinct nucleus with nuclear membrane. The cytoplasm of prokaryotic cells lacks in well defined cell organelles such as endoplasmic reticulum, Golgi apparatus, Mitochondria,centrioles, nucleoli, cytoskeleton. The size of these cells range between 1 micrometre to 3 micrometres, so they are barely visible under the light microscope. Now let's moveon to diagram. 1.Draw a capsule shape which represents a basic structure of Bacilli bacterial cell. Draw two more lines over basic capsule shape which represents Cell wall . Place some dots inside it. 2. Draw one more outer covering with considerable thickness.This represents outer slimy Capsule. Draw some faint oblique lines within to highlight it. 3.Draw several Pili around the Prokaryotic cell as shown, Make a whip like flagellum at the bottom of the cell. Note: A ...
How to draw DNA The DNA has twisted ladder or double helical structure. According to Watson and Crick DNA molecule consists of two polynucleotide chains wrapped helically around each other, with the sugar- phosphate chain on the outside forming ribbon-like backbone of double helix. Purines and pyrimidines on the inside of the helix projecting between two sugar phosphate backbones as transverse bars. The two polynucleotide strands are held together by hydrogen bonds between specific pairs of Purines and Pyrimidines. Now let's see how to draw DNA accurately. 1.Draw two vertical parallel lines as shown with pencil. 2. Draw a twisted wave touching two lines on either sides. 3. Draw another wavy curve as shown. Start the second curve a bit near the first curve to get proper grooves of DNA. 4. Make ribbon shape on the strands as sho...
