Here is an explanation sorry if it’s long :/
Nutrients are chemical substances found in every living thing on Earth. They are necessary to the lives of people, plants, animals, and all other organisms. Nutrients help break down food to give organisms energy. They are used in every process of an organism’s body. Some of the processes are growth (building cells), repair (healing a wound), and maintaining life (breathing).
Plants and other autotrophs absorb nutrients from soil and water. Autotrophs are organisms that can make their own food. The most important nutrients they need are carbon, hydrogen, and oxygen. Other nutrients needed by plants are nitrogen, phosphorous, potassium, calcium, magnesium, and sulfur.
From these basic nutrients, plants and other autotrophs synthesize, or create, their own nutrients, such as sugars. The human body can also synthesize some nutrients, such as amino acids. However, most organisms need nutrients created by autotrophs. People and animals get most of their nutrients from food.
Essential nutrients are nutrients that the human body is unable to synthesize. They must be obtained from food or water. Essential nutrients include carbohydrates, proteins, fats, vitamins, and minerals.
This makes sense because all scavengers eat, but not all eaters scavenge for food.<span />
<u>Role of Parenchyma cells-</u>
The two primary jobs of parenchyma cells are food storage and transport.
<u>Parenchyma cells-</u>
Parenchyma cells are cells that are living. These cells also have really thin-walls and a structure that is unspecialized. These cells can therefore perform a variety of functions. Parenchyma cells are present throughout a plant. These are present in the form of tissues which are homogenous. Parenchyma cells are present in both the stem and roots. This is the primary reason these cells are involved with the assimilation of nutrients and food. These cells are also present in the flesh of fruits and in seeds, and in the mesophyll of leaves which is why these cells can store food.
