These are the plants of the world. Plants have cellulose- containing cell wall. Their cell walls contain chloroplasts, which store food such as starch. Almost all of the members of this group reproduce sexually. The ability to manufacture their own food by means of photosynthesis and this possession of chlorophyll, the green photosynthetic pigment, is the most important distinction of plants from any other living organism.
Plants form the food, directly or indirectly, for every living thing on earth.
They also provide much of the worlds oxygen. Also, plants have no nervous system. Last of all is the Kingdom Animalia. This kingdom contains all organisms that develop from an embryo that has a blastula stage. Every member of Kingdom Animalia is heterotrophic and multicellular.
