cell membranes surround and protect cells they are made of special lipids called... phospholipids passing traits from parent to off-spring heredity
a molecule that carries energy cells atp energy one parent making off-spring asexual reproduction
large molecules made up of smaller molecules called amino acids protein the act of keeping a constant environment inside a organism homeostasis
breaks down dead organism waste to get food decomposer 2 parents making off-spring sexual reproduction
eat other organisms consumer/heterotrophic a change that affects how a organism acts stimulus
a nucleic acid controls the structure and function of cells when reproduce pass copies of their dna to off-spring dna the smallest unit that can carry out all the activities of life. Usually consist of cytoplasm, nucleus, and membrane cell
molecules made of sugar, starches, and fiber contains carbon hydrogen, and oxygen carbohydrates/simple and complex start or speed up chemicals reactions in cells enzymes
a molecule that is present in all living cells and plays a role in protein reproduction rna a group of organisms that are closely related and can mate to produce fertile offspring species
molecules made of different kinds of atoms compound how organisms act in different environments responce
a substance made when tow or more atoms combine molecule many cells grow by making more cells growth
how it developes development organisms that can live without air anaerobic
molecules made of smaller molecules called nucleotides nucleic acid make their own food from energy/sunlight producer/autotrophic
molecules that cannot mix with water lipids all the chemical reactions that takes place in its body metabolism
