Eukaryotic cells are cells that contain individual compartments for each particular function. Human cells are considered eukaryotic and can be easily drawn by drawing all of the internal pieces. The interior components of the cell are called organelles, each of which has a specific role in keeping the cell alive or accomplishing the cell's tasks.

Instructions

  1. 1

    Draw the outer wall of the cell known as the cell membrane. The cell membrane holds the cell together and is responsible for the entering and exiting of materials. Although human cells are not perfect spheres, they can be depicted as such or at least round.

  2. 2

    Fill the interior of the cell membrane with a transparent or fluid-like colour. This is the cytoplasm, which makes up the majority of the interior of the cell. The cytoplasm is a semi-fluid composed of water and nutrients that the cell uses in chemical reactions.

  3. 3

    Draw a large sphere within the cell to represent the nucleus. Make a small dark spot on the nucleus to represent the nucleolus. The nucleus is a thin-membrane sac filled with DNA-wrapped proteins. It also houses the nucleolus, which is similar to the nucleus but primarily consists of RNA-wrapped proteins.

  4. 4

    Draw a structure that resembles a ribbon folded back against itself several times. This folded structure is the endoplasmic reticulum, a long membrane that has folded repeatedly and plays a large role in the synthesising of proteins, such as the addition of sugars into a protein structure.

  5. 5

    Draw many small bumps on the end of the endoplasmic reticulum and several floating around the cytoplasm. These bumps, known as ribosomes, are the organelles responsible for protein synthesis. Ribosomes connected to the endoplasmic reticulum produce proteins for internal and external use, while free-floating ribosomes only produce proteins for use inside the cell.

  6. 6

    Draw a series of flat membranes similar to a stack of pancakes. The Golgi apparatus absorbs protein molecules created by the endoplasmic reticulum and ribosomes and finalises them by adding enzymes or cutting off pieces. It packages the finished proteins into small sacs called vesicles.

  7. 7

    Draw a group of tiny spheres called lysosomes. Lysosomes are sacs or vesicles filled with enzymes that break down substances. Lysosomes typically break down food or old unused organelles, but can break down the entire cell if broken open.

  8. 8

    Draw several oval shapes containing a squiggly line. These shapes represent mitochondria, an organelle that receives the broken-down food from the lysosomes and processes it into energy.

Tips and warnings

  • Perform a Web image search for "human cell" to locate artistic representations of human cells and their organelles. This can help to provide a better visual idea of how to draw the cell.
