Plant cells are eukaryotic cells that differ in several key aspects from the cells of other eukaryotic organisms. These distinctive features include the following: A large central vacuole, a water-filled volume enclosed by a membrane known as the tonoplast that maintains the cell's turgor, controls movement of molecules between the cytosol and sap, stores useful material and digests waste proteins and organelles. A cell wall composed of cellulose and hemicelluloses, pectin and in many cases lign
Penguin Natural Habitat. The habitat for penguins is going to depend on the type you are talking about. Some of them are able to live in the coldest parts of the world. Others live very close to the equator where it is quite warm.All penguins though reside within the Southern hemisphere.They are found on every single island there.he habitat for penguins is going to depend on the type you are talking about. Some of them are able to live in the coldest parts of the world. Others live very close to the equator where it is quite warm.
For example, the Galapagos penguin lives very well in these tropical islands; however, in a place where the water does not reach more than 28Âº C, in southern Africa, there is also a species of penguins. The biomes that inhabit penguins are coastal and oceanic, so they are always beside the sea, where they get their food.
