Why is it important for multicellular organisms to have specialized cells?

Multicellular organisms need many different types of cells to carry out the same life processes. Each of these special types of cells has a different structure that helps it perform a specific function. Cell differentiation is the process by which cells become specialized in order to perform different functions.

Why is it important that our cells are specialized for a specific function?

Cell specialization allows new cells to develop into a range of different tissues, all of which work together to make living organisms function as a whole.

What is the benefit of specialized cells to an organism?

Advantages: Every cell is specialized to do their own thing so: 1. They can focus on fewer tasks at once and do the work more efficiently 2. As all of the task require a certain amount of resources and energy to prepare, specialized cells save energy as they are always prepared 3.

Why do organisms need Specialised cells and tissues in order to survive?

Multicellular organisms need specialized systems The cells get oxygen and nutrients from this extracellular fluid and release waste products into it. Humans and other complex organisms have specialized systems that maintain the internal environment, keeping it steady and able to provide for the needs of the cells.

Why do multicellular organisms require Specialised organs for exchange of gases?

A reason is that multicellular organisms need special organs for exchange of gases with the environment because of prokaryotic cells found in the body. The cells are not in contact with the environment and therefore diffusion would not work in the exchange of gases. The organs in the body therefore serve this purpose.

Why do we need a Specialised exchange system to exchange the gases?

Substances can diffuse in and out at a high rate and easily reach all parts of the cell. They also need specialised exchange surfaces where substances can enter and leave the transport system by diffusion.

Why do multicellular organisms have to have organs?

Multicellular have differentiated cells that form the different tissues and organs (liver, heart, vessels etc) that carry out different functions for the survival of the organism.

Why diffusion is important for the movement of gases?

Diffusion is the movement of a substance from an area of high concentration to an area of lower concentration . Diffusion occurs in liquids and gases when their particles collide randomly and spread out. Diffusion is an important process for living things – it is how substances move in and out of cells.

What is the need for exchange surfaces in multicellular organisms?

Larger multicellular organisms have smaller surface area to volume ratios. So, they have evolved exchange surfaces to exchange molecules with their surroundings.

What is the importance of diffusion in organisms?

Diffusion is important to cells because it allows them to gain the useful substances they require to obtain energy and grow, and lets them get rid of waste products.

What is diffusion and why is it important?

Diffusion can occur across partialy permeable membranes, such as those surrounding cells. Therefore, diffusion is involved in the movement of important molecules into and out of cells. It is important for the uptake of substances needed by cells, and also the removal of waste products produced by the cells.
