Prokaryotes and Eukaryotes Flashcards
what is a eukaryotic cell?
A cell with genetic material (DNA) enclosed in a nucleus e.g. animal and plant cells
What is a prokaryotic cell?
•A cell with genetic material (DNA) not enclosed in a nucleus e.g. bacteria
•they are usually much smaller in comparison to eukaryotic cells
what 5 organelles does an animal cell consist of?
nucleus,cytoplasm,cell membrane,mitochondria,ribosomes
what 8 organelles does a plant cell consist of?
nucleus, mitochondria, cell membrane, cytoplasm, ribosomes, cell wall, vacuole and chloroplasts
what is the function of the nucleus?
It controls the activities of the cell and is where DNA is found
what is the function of cytoplasm?
This is where most chemical reactions take place
what is the function of ribosomes?
This is where protein synthesis occurs
what is the function of the mitochondria?
It is a site of aerobic respiration where energy is transferred
what is a chloroplast?
light is absorbed here for photosynthesis and it also contains green chlorophyll
what is the function of the cell wall?
it provides the plant with strength and support to stop it from bursting
what is the function of the vacuole?
This is filled with cell sap
what is the function of the cell membrane?
it holds the cell together and controls what goes in and out
what 8 organelles do bacteria cells consist of?
cell wall,cell membrane, ribosomes, plasmids,cytoplasm, capsule,flagellum,pilli
what is the function of a plasmid?
It is a small circle of DNA
what is the function of a capsule?
It protects the bacteria cell and prevents drying out
