Cell Structure Flashcards
What is the function of the cell wall?
To support the cell
What is the function of a mitochondrion?
The site of aerobic respiration; releases energy for the cell
What is the function of a chloroplast?
Site of photosynthesis; contain green chlorophyll
What is the function of the cytoplasm?
Site of important biochemical reactions
What is the function of a vacuole?
Stores water and solutes as cell-sap and regulates water content by osmosis
What is the function of the nucleus?
Controls the cell’s activities; contains genetic information
What is the function of a ribosome?
Site of protein synthesis
What is the function of a cell-membrane?
To control the passage of substances into and out of the cell; semi-permeable
What is the function of a plasmid?
Rings that contain extra genetic material in bacterial cells; can be used as vectors in genetic engineering
What are cell walls made of in plant cells?
Cellulose
What are cell walls made of in plant cells?
Cellulose
What are cell walls made of in bacterial and fungal cells?
Different materials each; different materials from cellulose
What is the structure of a bacterial cell?
Absence of membrane-bound organelles; a cell membrane; a cell wall (different structure to plant and fungal cells); a large circular chromosome; small circular plasmids, ribosomes, and a cytoplasm.
What is the structure of an animal cell?
A cell membrane, mitochondria, a nucleus, ribosomes, and a cytoplasm
What is the structure of a plant cell?
A cell wall (made of cellulose), a cell membrane, mitochondria, chloroplasts, a permanent vacuole, a nucleus, ribosomes, and a cytoplasm
