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 huddle to keep warm. The warm air gets trapped between the penguins' bodies and feathers (like air being trapped under your clothing) as each penguin's body heat will circulate to the others around them. Now remember that besides the freezing temperatures, there are also harsh winds where these penguins live.ir is a good insulator and so it will trap the body heat of the penguins. It also makes the whole group of penguins warmer and the product of all the penguin's body heat is g â¦ reater that of just one penguin other than that, they will also rotate around with the penguins on the outside. 4 people found this useful. .
