Answer:
There are many benefits of bearing fruits. Please read the explanation section.
Explanation:
A fruit is the part of flowering plants. Fruit contains the seeds of the plant. These seeds help the plants to reproduce its next generation. Some fruits are fleshy like berries; some are hard like nuts. The fruit helps to protect the seeds.
Along with this, the fruit helps the seeds to be spread out. Many fruits are attractive because of their color and aroma. They attract small animals like birds, squirrels. They eat those fruits. After eating, the animals move from one place to another. With them, the seeds move too. When those animals poop, the seeds are coming out with their poop. Then the seed can grow at that place.
Answer:
diverse proteins embedded in a phospholipid bilayer
Explanation:
According to fluid mosaic model the cell membrane is made of bilayer of phospholipid. Many proteins are embedded in this bi layer. Carbohydrate and cholesterol are also found in different forms. Carbohydrate can either be attached to the embedded protein in which case it is called as glycoprotein or it can be connected to the lipid molecule in layer and called as glycolipid.
Proteins can be found in two forms too. They can either be embedded in the layer i.e. they can penetrate single or both layers. These proteins are called as integral proteins. They can also be present on one side of the membrane and not penetrate the lipid bilayer in which case they are called as peripheral proteins.
