Lab 10: Cell Structure & Funcon
NOT SHOWN:
Eukaryotes:
• Glycocalyx: A “slime coang” on some prokaryoc cells that helps protect the cell
and enables it to aach to “unconvenonal” surfaces (i.e. teeth, lungs, arficial
joints).
• Thylakoid: Extensions of the plasma membrane of cyanobacteria containing photosynthec
pigments.
• Flagella: Long cylindrical protrusions that rotate to provide mobility.
• Pili: Hair like extensions on the cell surface that transmit genec informaon and
help secure the bacteria to its host.
Figure 2: Structures unique to eukaryotes
NOT SHOWN:
• Nucleolus: A part of the nucleus that is made of RNA, Protein and Chroman and
manufactures RNA and ribosomes.
• Cytoskeleton: The “skeleton” found in all eukaryoc cells that provides shape to
the cell while also enabling it to move. It consists of three parts:
