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.

Penguins are especially abundant on islands in colder climates, and they tend to remain in areas that are isolated and free of most predators. In all, there are 17 different species of penguin in the world, and not all of them live in cold climates like we imagine.The majority of penguin species do prefer colder climates, although there are even some penguins that are native to some of the tropical climates located right at the equator.enguins are especially abundant on islands in colder climates, and they tend to remain in areas that are isolated and free of most predators.
