1. Draw an image of a Prokaryotic cell in the space below. Label all the organelles and
structures present in a typical prokaryotic cell.
2. Complete the following table by listing various organelles and structures commonly found in
a Prokaryotic cell and describe their functions in 1-2 sentences.
Organelles and Structures of
Prokaryotic Cell
Function
Cell wall The cell wall provides protection for the cell by maintain
the cell’s shape, protects the cell interior, and prevents
the cell from bursting when it fills with water.
Flagella The Flagella is responsible for moving the cell forward
and providing motility. The prokaryotic flagellum spins,
creating forward movement.
Pili The Pili is responsible for transferring of genetic material
between the cells. They adhere to surfaces which
facilitates infection.
Capsule Capsule is responsible for protecting the cell from
ingestion and destruction by white blood cells. The
capsule helps cling to each other and to various surfaces.
Fimbriae Fimbriae are hairlike structures with bristles that help
with adhering to other cell surfaces.
Nucleoid Nucleoid contains the genetic material. It is essential for
controlling the activity of the cell and reproduction.
Ribosome Ribosomes are responsible for protein synthesis. The
main purpose is to translate messenger RNA to proteins
with the aid of tRNA.
Cell membrane The cell membrane is responsible for regulating what
comes into the cell. The cell membrane encloses the cell
and protects it, only allowing certain molecules to come

in. Plasmid Plasmids are responsible for carrying genes throughout the body. Cytoplasm Cytoplasm is water-based solutions that fill the cell. The cytoplasm is where the functions for cell growth, metabolism, and replication are carried out. Cytoskeleton The Cytoskeleton provides the cell with mechanical support. The cytoskeleton plays an essential role in cell division, protection, shape determination, and polarity.

  1. Draw an image of a Eukaryotic cell in the space below. Label all the organelles and structures present in a typical Eukaryotic cell.

The differences between Prokaryotic and Eukaryotic cells are that eukaryotic cells have a nucleus, cytoskeleton, while prokaryotic cells do not. Prokaryotic cells are small whereas Eukaryotic cells are larger in size. The differences in transcription and translation are that prokaryotic cells begin translation during mRNA synthesis and eukaryotic cells transcription occurs in the nucleus, producing mRNA.
