what characteristics do all the organisms in the animal kingdom share
Animal Animals are eukaryotic, multicellular organisms that form the biological kingdom Animalia. With few exceptions, animals are motile (able to move), heterotrophic (consume organic material), reproduce sexually, and their embryonic development includes a blastula stage. The body plan of the animal derives from this blastula, differentiating specialized tissues and organs as it develops; this plan eventually becomes fixed, although some undergo metamorphosis at some stage in their lives.
Gene Organisms inherit their genes from their parents. Asexual organisms simply inherit a complete copy of their parent's genome. Sexual organisms have two copies of each chromosome because they inherit one complete set from each parent.[25]:1
Animal Animals have several characteristics that set them apart from other living things. Animals are eukaryotic and multicellular,[5][6] which separates them from prokaryotic bacteria and eukaryotic but unicellular protists. Unlike plants and algae, which produce their own nutrients (and, with fungi, have rigid cell walls),[7] animals are heterotrophic,[6][8] consuming organic material and digesting it internally.[9] With very few exceptions, animals breathe oxygen and respire aerobically.[10] All animals are motile[11] (able to spontaneously move their bodies) during at least part of their life cycle, but some animals, such as sponges, corals, mussels, and barnacles, later become sessile. The blastula is a stage in embryonic development that is unique to most animals,[12] allowing cells to be differentiated into specialized tissues and organs.
Seed Seeds are the product of the ripened ovule, after fertilization by pollen and some growth within the mother plant. The embryo is developed from the zygote and the seed coat from the integuments of the ovule.
