What are pili?
Hairs that allow cells to stick to other cells, present on prokaryotic cells
What is a flagella?
The tail that propels prokaryotic cells
What is the capsule?
The outer wall of prokaryotic cells
What is the cell wall?
The wall that supports the cell
What is the cell/plasma membrane?
The permeable wall that regulates the entrance of molecules
What is DNA?
The genetic material of cells
What is the cytoplasm?
The inside goo of cells that holds everything together
What is the plasmid?
A small loop of DNA in prokaryotic cells
What are ribosomes?
Small dots that assemble proteins
What is the cytoskeleton?
The thin film in between the cell membrane and cytoplasm of eukaryotic cells that help them maintain shape
What is the nucleus?
The “brain” that holds the DNA in eukaryotic cells
What does the vacuole do?
Stores materials in eukaryotic cells
What is the smooth endoplasmic reticulum?
The wavy lines WITHOUT ribosomes that make substances such as lipids in eukaryotic cells
What is the rough endoplasmic reticulum?
The wavy lines WITH RIBOSOMES that make proteins in eukaryotic cells
What does the mitochondria do?
Turns chemical energy into food in eukaryotic cells
What does the Golgi apparatus do?
Modifies and sorts materials for storage or release in eukaryotic cells
What are chloroplasts?
Green balls that undergo photosynthesis in eukaryotic cells
What are centrosomes (centriole)?
The connector-looking pieces that have the function of cell motility and organization in eukaryotic cells
What are lysosomes?
Big dots that break down chemical energy into useful and junk in eukaryotic cells
