What are the different parts of a cell called?
• subcellular structures
What is the function of the nucleus in an animal and plant cell?
• contains DNA coding for a particular protein needed to build new cells • controls activities of the cell • enclosed in a nuclear membrane
What is the function of the cytoplasm in an animal and plant cell?
• gel-like substance • where most of the chemical reactions happen • contains enzymes that control chemical reactions • organelles are found in it
What is the function of the cell membrane in an animal and plant cell?
• hold the cell together • controls what goes in and out
What is the function of the mitochondria in an animal and plant cell?
• most of the reactions for aerobic respiration take place • respiration transfers energy that the cell needs to work
What is the function of the ribosomes in an animal and plant cell?
• protein synthesis • where proteins are made • found on the rough endoplasmic reticulum
What is the function of the cell wall in a plant cell and algal cells?
• rigid • made of cellulose • supports the cell and strengthens it
What is the function of the permanent vacuole in a plant cell?
• contains cell sap • a weak solution of sugar and salts • found within the cytoplasm • improves cell’s rigidity
What is the function of the chloroplasts in a plant cell?
• where photosynthesis occurs • makes food for the plant • contain chlorophyll pigment which absorbs light needed for photosynthesis
What are the subcellular structures of a bacterial cell?
• cytoplasm • cell membrane • cell wall • singular strand of DNA/plasmids • ribosomes
What is the cell wall in a bacterial cell made up of?
• peptidoylcan
