8 Cell Components And Functions Flashcards
Absorption
The movement of substances from the external environment across the cell membrane into its internal environment of a cell organism
Amino acid
A nitrogen containing compounds that is a building block of proteins
Assimilation
The process through which an organism incorporates nutrients from outside its body into the more complex structures needed, and it’s fluid or solid parts
Autotroph
An organism capable of making its own food from inorganic substances
Biomacromolecule
A molecule that has an important structure or function role in cells
Cell
Basic structural unit for all life on earth
Cellular respiration
Glucose and oxygen, to produce CO2 and water. Energy released converts ADP to ATP
Chemosynthesis
Synthesis of organic substances using energy from chemical reactionS
Chlorophyll
Green pigment found in chloroplasts, which absorbs light energy for photosynthesis
Chloroplast
A membrane browned organelle found in the cytoplasm of plants and algae. Function is to be the site of photosynthesis and storage of carbohydrates.
Christae
Folded in a membrane in the matrix of the mitochondria to provide increase surface area for cellular respiration
Disaccharide
Two. Linked monosaccharide molecules.
DNA
Deoxyribonucleic acid a molecule that is the universal basis of genetic material contains instructions written in chemical code for production of proteins
Electron microscope
Scope that uses an electron beam instead of light and electromagnets, instead of glass lenses interactions between the electrons and the object recorded on a photo photographic plate, which then forms a viewable image on screen
endoplasmic reticulum
Organelles in eukaryotic cells, consisting of an interconnecting system of thin membrane sheets dividing the cytoplasm into compartments and channels. Lipid synthesis occurs here.
Endosymbiotic theory
Siri suggesting that chloroplasts and mitochondria arose from ancient prokaryotic cells that were ingested by other prokaryote host cells
Eukaryote
Complex type of cell with a nucleus and membrane bound organelles
Golgi apparatus
A collection of membranes that package and store substances into vessels in preparation for the release from the cell
Glycoprotein
A protein molecule with an attached carbohydrate chain
Heterotrophs
An organism that cannot synthesise its own organic compounds from simple organic materials, instead, depending on other organisms for nutrients and energy
InTERcellular Vs inTRAcellular
Intercellular occurring between cells
Intracellular occurring within a cell
Lipid
An organic molecule that includes fat oils and is insoluble in water
Lysosome
Organelle within the cytoplasm containing digestive enzymes
