Biology Collection 1: Claire Wray
This is a picture of a cuticle of a plant: a waxy coating that is secreted by the leaf and stem of the plant allowing the plant to retain water.
This is a picture of Genetically Modified Organism:an organism whose genetic material has been altered using genetic engineering techniques.
This is a fleshy fruit with seed: a mature ovary of a flower that protects dormant seeds and aids in their dispersal and has a plumb, fleshy outer layer.
This is a picture of muscle fiber(striated):an elongated contractile cell in striated muscle tissue
This is a picture of a Eukaryote: any organism having as its fundamental structural unit a cell type that contains specialized organelles in the cytoplasm, a membrane-bound nucleus enclosing genetic material organized into chromosomes, and an elaborate system of division by mitosis or meiosis, characteristic of all life forms except bacteria, blue-green algae, and other primitive microorganisms.
This is a picture of a insect: any animal of the class Insecta, comprising small, air-breathing arthropods having the body divided into three parts (head, thorax, and abdomen), and having three pairs of legs and usually two pairs of wings.
This is a picture of autotroph: an organism that obtains organic food molecules without eating other organisms. Autotrophs use energy from the sun or from the oxidation of inorganic substances to make organic molecules from inorganic ones.
This is a picture of Fermentation: a catabolic process that makes a limited amount of ATP from glucose without an electron transport chain and that produces a characteristic end-product, such as ethyl alcohol or lactic acid.
This is a picture of Ethylene: a gaseous plant hormone(located in the petals), responsible for fruit ripening, growth inhibition, leaf abscission, and aging.
this is a picture of Cellulose: a structural polysaccharide of cell walls, consisting of glucose monomers joined by beta-1, 4 glycosidic linkages.
