Cellular Structure and Function

membrane-bound structure with special functions within eukaryotic cells

• Nucleus

• Cell wall
• Cytoplasm
• Organelle

What is the difference between prokaryotic and eukaryotic cells

• Prokaryotic cells and eukaryotic cells are the same.
• Prokaryotic cells have organelles, while eukaryotic cells do not have organelles.

• Prokaryotic cells have a larger size compared to eukaryotic cells.
• Prokaryotic cells do not have organelles, while eukaryotic cells have organelles.

protein that moves needed substances or waste materials through the plasma membrane into or out of the cell

• selective permeability

• phospholipid bilayer

• transport protein

• enzyme

this organelle is a flattened stack of

membranes that modifies, sorts, and

packages proteins.

• Mitochondria
• Lysosome
• Endoplasmic reticulum
• Golgi apparatus

what is the organelles that make proteins

• nucleus
• mitochondria
• chloroplasts
• ribosomes

a thick, rigid mesh of fibers surrounding the outside of the plasma membrane in plant cells,

that protects the cell and gives it structure

• Cell wall
• Golgi apparatus

• Ribosome

• Lysosome

this organelle is a membrane

system of folded sacs and interconnected

channels that serves as the site for protein and

lipid synthesis.

• Endoplasmic reticulum
• Golgi apparatus
• Mitochondria
• Lysosomes

organelles that contain substances

that digest excess or worn-out organelles,

they also digest bacteria or viruses that invade

the cell

• Mitochondria
• Golgi apparatus
• Endoplasmic reticulum
• Lysosomes

organelles that act as temporary storage for materials such as food or waste in the cytoplasm.

• nucleus
• mitochondria
• ribosomes
• vacuoles

The environment inside the plasma membrane is a semifluid material called

• endoplasmic reticulum

• cytoplasm
• mitochondria

• chloroplasts
