Cells of animals can vary in size and shape, but they have many features in common. The diagram shown is a cell that might be found lining the intestines. Color according to the directions below; the numbers correspond to the numbers on the cell diagram.
- The cell membrane surrounds the cell and acts as a barrier. It controls what comes in and out of the cell. Color the membrane light brown.
- The membrane can have structures on its surface that help the cell move, or move particles within the body. This cell has structures called cilia which can serve to sweep particles past the cells. Color the cilia yellow.
- Animal and plant cells are both eukaryotes, meaning they have their DNA enclosed in the nucleus. The DNA contains the cell’s genetic information which then controls the cell’s activities. Color the nuclear membrane dark brown.
- Within the nucleus is a structure called the nucleolus, whose job is to make ribosomes. Color the nucleolus black.
- DNA can be wound around proteins and create large visible structures in the nucleus called chromosomes. Color the chromosomes dark green.
- The interior of the cell is made of a fluid called cytoplasm. Embedded in the cytoskeleton are microtubules that help the cell maintain its shape and form. Color the microtubules green.
- Throughout the cell are small round structures called ribosomes. They receive instructions from the nucleus to make proteins that will serve as the organism’s building blocks for making blood, muscle, and other tissues. Ribosomes can be found all throughout the cytoplasm, but many are located on the endoplasmic reticulum. Find all the ribosomes and color red.
- The rough endoplasmic reticulum (rough E.R.) appears bumpy because it has many ribosomes attached. Its main job is to transport substances throughout the cell, mainly proteins. Color the rough E.R. light blue.
- The smooth endoplasmic reticulum looks similar to the rough, but it does not have ribosomes. It has a few jobs, such as creating and storing lipids. Color the smooth E.R. light blue.
- Cells need to have a source of energy to power all of its processes. The mitochondria takes glucose from food and converts it into a form of cellular energy called A.T.P. Color the mitochondria orange.
- Some cells have special structures used for digesting substances. For instance, cells in your mouth have lysosomes that contain enzymes to begin breaking down food. Color the lysosomes purple.
- Proteins made by the ribosomes eventually reach the golgi apparatus. Here the proteins are packaged into vesicles which can be exported out of the cell to the part of the body that needs them. Color the golgi apparatus pink.
- Proteins will exit the cells in packages called vesicles, which appear as bubbles near the golgi apparatus. Color the vesicles yellow.
