Cell Biology Flashcards
What is Aerobic respiration?
Release of energy from food by a cell using oxygen.
what is a Cell Membrane?
Selectively permeable membrane enclosing the cell cytoplasm and controlling the entry and exit of materials.
What is the function of a cell wall?
Supports and prevents cells from bursting: plant, fungal and bacterial walls have different structures and chemical compositions.
What is Cellulose?
Structural carbohydrate of which plants cell walls are composed.
What is Chloroplast?
Organelle containing chlorophyll: The site of photosynthesis.
What is Cytoplasm?
Jelly-Like liquid containing cell organelles and the site of many chemical reactions.
What is DNA?
Substance in chromosomes that carries the genetic code of an organism.
What is a Mitochondrion?
Organelle that is the site of Aerobic Respiration and ATP production in cells.
What is a Nucleus?
organelle that is the control centre centre of a cell containing the genetic information of the organism.
What is Photosynthesis?
The process carried out by green plants to make their own food using light energy.
What is a Plasmid?
Circular genetic material present in bacterial cells and used in genetic engineering or modification.
What is a Protein?
Substance composed of chains of amino acids and containing the elements Carbon, Hydrogen, Oxygen and Nitrogen.
What is a Ribosome?
Site of protein synthesis.
What is a Vacuole?
Membrane-bound sac containing cell sap in plant and fungal cells.
Name two structures that are found in all cells.
Cell membrane, Ribosome.
