Flashcards in Cell Biology Deck (15):
What are eukaryotic cells?
Animal and plant cells
What are prokaryotic cells?
Bacteria cells- they are much smaller and simpler
What is a nucleus?
Contains genetic material that controls the activities of the cell
What is a mitochondria?
These are where most of the reactions for aerobic respiration takes place. Respiration transfers energy that the cell needs to work
What is cytoplasm?
Gel-like substance where most of the chemical reactions happen. It contains enzymes that control these chemical reactions
What is a cell membrane?
It holds the cells together and controls what goes in and out of the cell
What are ribosomes?
Where proteins are made in the cell
What are cell walls?
Made of cellulose. It supports the cell and strengthens it
What are chloroplasts?
Where photosynthesis occurs, which makes food for the plant. They contain chlorophyll, which absorbs the light needed for photosynthesis
What is a vacuole?
Contains cell sap, a weak solution of sugar and salts
What are plasmids?
One of more small rings of DNA
What do bacteria cells have instead of a ‘true’ nucleus
They have a singular circular strand of DNA that floats freely in the cytoplasm
What are the differences between an electron microscope and light microscope?
What is differentiation?
The process by which a cell changes to become specialised for its job
