Question

Name the process and also explain how food and other substance enter how food and other substance enter through plasma membrane

Answer 1

In simple diffusion, small molecules without charges such as oxygen and carbon dioxide flow through a plasma membrane without assistance and without expending energy. Other substances such as proteins, glucose and charged particles called ions cannot pass through the selectively permeable membrane.

Answer 2

Diffusion is the process by which the substances and food enter through plasma membrane.

Diffusion is the well known process in which the substances are diffused from higher concentration to lower concentration.

The characteristics of plasma membrane are permeable so hydrophobic molecules and some polar molecules which are small usually diffuse through lipid layers but ions and molecules which are large cannot.

Energy is required to transport substance across the membrane called plasma membrane. The transport is called active if the energy is used.
