The Phospholipid molecule Hydrophilic –“water loving” Hydrophobic –“water fearing” Draw and label this: title: The cell membrane is a phospholipid bilayer - this means that there are two rows of phospholipid molecules with the fatty acid tails in the middle making it nonpolar. The phosphate...
2. Add the Cell Wall: - Draw a thick line around the rectangular shape to represent the cell wall. This structure is rigid and provides support and protection to the plant cell. 3. Draw the Cell Membrane: - Inside the cell wall, draw another line that closely follows the shape of the...
- Finally, draw the long, whip-like tail extending from the middle piece and label it as the "Tail." This part is responsible for the movement of the sperm. Step 7: Add the Plasma Membrane - Draw a thin line around the entire sperm structure to represent the "Plasma Membrane." This ...
First, we will be drawing the outer membrane that covers the exterior of the cell. To do this, simply draw a line running parallel to the opening of the cell that you drew in the previous step. As seen in the reference picture, this will show the outer coating of the cell. Then, we...
