list and describe the main characteristics of the kingdom animalia
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.
Fox Foxes are small-to-medium-sized, omnivorous mammals belonging to several genera of the family Canidae. Foxes have a flattened skull, upright triangular ears, a pointed, slightly upturned snout, and a long bushy tail (or brush).
Plant Plants are one of the two groups into which all living things were traditionally divided; the other is animals. The division goes back at least as far as Aristotle (384 BC – 322 BC), who distinguished between plants, which generally do not move, and animals, which often are mobile to catch their food. Much later, when Linnaeus (1707–1778) created the basis of the modern system of scientific classification, these two groups became the kingdoms Vegetabilia (later Metaphyta or Plantae) and Animalia (also called Metazoa). Since then, it has become clear that the plant kingdom as originally defined included several unrelated groups, and the fungi and several groups of algae were removed to new kingdoms. However, these organisms are still often considered plants, particularly in popular contexts.
