Animal Cell Coloring Answers Printable
Animal cells are the basic unit of life in organisms of the kingdom Animalia. They are eukaryotic cells, meaning that they have a true nucleus and specialized structures called organelles that carry out different functions. Animal cells do not have cell walls or chloroplasts, the organelle that carries out photosynthesis.
Animals, plants, fungi, and protists all have eukaryotic cells, while bacteria and archaea have simpler prokaryotic cells. Eukaryotic cells are distinguished by the presence of a nucleus and other membrane-bound organelles. Animal cells, unlike plants and fungi cells, do not have a cell wall. Instead, multicellular animals have a skeleton that provides support for their tissues and organs. Likewise, animal cells also lack the chloroplasts found in plants, which is used to produce sugars via photosynthesis.
As such, animal cells are considered heterotrophic, as opposed to autotrophic plant cells. This means that animal cells must obtain nutrients from other sources, by eating plant cells or other animal cells. However, like all eukaryotic cells, animal cells have mitochondria. These organelles are used to create ATP from various sources of energy including carbohydrates, fats, and proteins.
Besides mitochondria, many other organelles are found within animal cells which help them carry out the many functions required for life. The cell has a variety of different parts. It contains many different types of specialized organelles that carry out all of its functions. Not every animal cell has all types of organelles, but in general, animal cells do contain most if not all of the following organelles.
