What is the structure and function of the cell wall?
A structural layer that surrounds the cell membrane of some cells, providing support, protection, and shape.
What is the structure and function of the Plasma membrane?
separates the interior of the cell from the outside environment.
found in all cells.
regulates the transport of materials entering and exiting the cell.
has a fluid structure and is made up of a double layer of phospholipids, called a lipid bilayer.
What is the structure and function of a Mesosome?
A complex membranous structure in a prokaryotic cell that's formed when the plasma membrane invaginates.
They are similar to the mitochondrial cristae of eukaryotic cells.
They have many functions including:
Cell membrane synthesis, DNA replication, Protein synthesis, Chromosome distribution, Enzymatic activities, Secretion processes, and Bacterial respiration.
What is the structure and function of a Ribosome?
Made up of 2 sub units: 1 large and 1 small.
Responsible for protein synthesis
Made up of RNA and are located in the cytoplasm or on the endoplasmic reticulum.
What is the structure and function of Circular DNA?
found in bacteria, mitochondria, and chloroplasts.
forms a closed loop structure with no free ends, providing stability and allowing for efficient replication and transcription.
What is the structure and function of the Cystoplasm?
Provides a medium for chemical reactions and cell processes, and maintains cell shape and structure.
Name the 4 organelles that are found in some prokaryotic cells but not all
Cilia (used for movement)
Flagella (used for movement)
Capsule or Slime Layer (an outer layer made of polysaccharides, which can be a capsule or a slime layer)
Pili (These are short, hair-like appendages that help bacteria adhere to surfaces)
Describe the structure of a virus.
a simple structure consisting of genetic material (DNA or RNA) encased in a protein shell called a capsid, and some viruses also have an outer envelope.
Eukaryotic cells all contain a nucleus. Describe the structure of a nucleus including the functions of each structure it contains.
