pseudopod structure in ameoba used for movement by cytoplasmic streaming
organic molecules such as carbohydrates, proteins and lipids contain carbon
negative chemotaxis moving away from a harmful chemical
activation site the part of the enzyme substrate complex where the enzyme binds with the substrate
passive immunity when an individual receives pre made antibodies. example mother passing immunity to baby through breast milk.
kidney used in complex animals to remove excess water and nitrogen

transpiration how plants move excess water and oxygen out of their leaves, similar to respiration in animals
guard cells cells that surround the stoma and prevent excess water loss by closing the stoma
