In order to be classified as a green plant, an organism should be eukaryotic, have double-membraned chloroplasts, cell walls, and go through the process of . Land plants likely evolved from . Plants have a life cycle that is called the alternation of generations. The two phases of this life cycle are the diploid stage and the stage. A plant structure that contains a full set of paired chromosomes is called a . There are two key transport tissues in plants. transports water from the roots to the rest of the plant, while phloem transports sugar and nutrients.

several tissues working together form an organ, and several organs together make up an organisms.

the group of cell that carries out special jobs are tissue.
