The fortnight Anne spent in Bolingbroke was a very pleasant one, with a little under current of vague pain and dissatisfaction running through it whenever she thought about Gilbert.
Cell wall. Many types of prokaryotic and eukaryotic cells have a cell wall. The cell wall acts to protect the cell mechanically and chemically from its environment, and is an additional layer of protection to the cell membrane. Different types of cell have cell walls made up of different materials; plant cell walls are primarily made up of cellulose, fungi cell walls are made up of chitin and bacteria cell walls are made up of peptidoglycan.
All animal cells are eukaryotic, they are surrounded by cell membrane and do not have a cell wall. The components of animal cells are centrioles, cilia and flagella, endoplasmic reticulum, Golgi apparatus, lysosomes, microfilaments, microtubules,mitochondria, nucleus, peroxisomes, plasma membrane and ribosomes.There are many different cell types, approximately 210 distinct cell types in adult human body.ell Wall: Cell wall is seen only in plant cell. It is made of cellulose. The function of the cell wall is to support,protect and allow diffusion of gases in and out of the cell. The strength of the cell walls help the tree to stand tall and grow against gravity.
