Prokaryotic Vs Eukaryotic Cells Flashcards
What are the two main types of organisms based on cell structure?
Organisms can be Prokaryotes or Eukaryotes.
What are Eukaryotic cells?
Eukaryotic cells are complex and include all animal and plant cells.
What are Prokaryotic cells?
Prokaryotic cells are smaller and simpler, such as bacteria.
What is the function of the nucleus in an animal cell?
The nucleus contains genetic material that controls the activities of the cell.
What happens in the cytoplasm of an animal cell?
The cytoplasm is a gel-like substance where most chemical reactions happen, containing enzymes that control these reactions.
Where does aerobic respiration occur in an animal cell?
Aerobic respiration takes place in the mitochondria.
What is the role of the cell membrane?
The cell membrane holds the cell together and controls what goes in and out.
What do ribosomes do in an animal cell?
Ribosomes are where proteins are made in the cell.
What additional structures do plant cells have compared to animal cells?
Plant cells have a rigid cell wall, permanent vacuole, and chloroplasts.
What is the function of the rigid cell wall in plant cells?
The rigid cell wall supports and strengthens the cell.
What is contained in the permanent vacuole of a plant cell?
The permanent vacuole contains cell sap, a weak solution of sugar and salts.
What occurs in chloroplasts?
Photosynthesis occurs in chloroplasts, which makes food for the plant.
What is unique about bacterial cells compared to eukaryotic cells?
Bacterial cells don’t have a ‘true’ nucleus; they have a single circular strand of DNA that floats freely in the cytoplasm.
What are plasmids in bacterial cells?
Plasmids are small rings of DNA that may be present in bacterial cells.
What structures do bacterial cells lack?
Bacterial cells lack chloroplasts, a nucleus and mitochondria.
