Make the circle large enough to decipher all the organelles you draw inside.

In pinocytosis the cell membrane wraps around extracellular fluids (those outside the cell). It then pulls the fluid into the cell for digestion or absorption. [3] X Research source This is why you draw the vesicle as a bulbous shape that the membrane has wrapped around.

The nucleus of an animal cell has pores in it called nuclear pores. [5] X Research source To represent these pores, erase three or four small sections of each circle. Then connect the outer lines to the inner lines. The finished product will resemble curved cylinders that don’t quite touch. [6] X Research source This outer shell of the nuclear membrane is also called the nuclear envelope. [7] X Trustworthy Source PubMed Central Journal archive from the U. S. National Institutes of Health Go to source To make a highly detailed cell model, put several dots on the outside of the nuclear membrane to represent ribosomes that attach to the membrane.

Leave a gap between the oval of the outer membrane and the inner membrane. [19] X Research source

Animal cells have both a smooth and a rough endoplasmic reticulum. To make the rough endoplasmic reticulum, place dots on the outside edge of the finger-like shapes on one side of the endoplasmic reticulum. These dots represent ribosomes. [22] X Research source

The Golgi body packages and sends complex molecules around and out of the cell. It does this via vesicles that you can represent around the Golgi body with a few small circles. [25] X Research source [26] X Research source Capitalize Golgi since it is the name of the discovering biologist.

The centrioles are paired organelles, which is why you draw two of the rectangles together. [30] X Research source

You can place the lysosome near the Golgi apparatus since the organelles are often budded from the Golgi body. [35] X Research source

If you have color-coordinated your drawing, make the ribosomes in the cell, attached to the nuclear membrane, and attached to the rough endoplasmic reticulum all the same color. Cytosol and cytoplasm are often used interchangeably for the fluid in the cell. [37] X Research source Though the fluid in the nucleus is nucleoplasm. [38] X Research source
