Explain how does diffusion take place in both animal and plant cells

The movement of various substances into a plant, usually from the soil, out of which the green plant synthesises the numerous complex organic compounds, is accomplished, principally through the agency of the process known generally as diffusion.

In some cases, however, the operation of the diffusion phenomena is complicated by other factors

the abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. the region occupied by the abdomen is termed the abdominal cavity. the stomach secretes acid and enzymes that digest food. ridges of muscle tissue called rugae line the stomach. the stomach muscles contract periodically, churning food to enhance digestion. the pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.
