The cell membrane is a lipid bilayer made of amphipathic phospholipids, which is fluid and selectively permeable to ions and organic molecules, given that the inside of the cell membrane is hydrophobic and the outside is hydrophilic.
The physical characteristics of the cell membrane, along with the proteins and other biomolecules embedded in it, control what enters and leaves the cell.
What the cell membrane DOESN'T do, is control the nucleus of the cell.
Answer:
Glucose is quickly broken down by liver and muscle cells to provide energy, which demonstrates that its type of chemical bonds is related to its function.
In agroecosystems, farmers practice monoculture. It is a practice of growing one type of crop in the same field year after year. Monoculture is an attempt to check herbivores from eating crops. As a result population of herbivores get reduced from the food webs. Using different types of agro-chemicals such as insecticides, pesticides, weedicides also reduces number species. Therefore, the most unusual characteristic of food webs in agroecosystems is lack of biodiversity.
