A transport system is needed in multicellular organisms to efficiently distribute essential nutrients, gases, and waste products throughout the body. This system allows for the rapid and coordinated movement of materials to and from cells located far from the external environment. In multicellular organisms, individual cells are specialized for specific functions, and a transport system ensures that these specialized cells can work together effectively to maintain homeostasis and support the overall functioning of the organism.
What else can I help you with?
Give two reasons why lower organisms eg bacteria and simple multicellular do not have an elaborate transport system?
Lower organisms like bacteria and simple multicellular organisms do not have an elaborate transport system because their small size allows for nutrients and gases to easily diffuse across their cell membranes. Additionally, their simple body structures do not require the complexity of a specialized transport system as they can rely on passive diffusion for their basic needs.
What involves the movement of materials inside the cell as well as the movement between parts of a multicellular organism?
The processes that involve the movement of materials inside a cell are called intracellular transport, which includes mechanisms like endocytosis, exocytosis, and molecular motor proteins. In multicellular organisms, the movement between different parts is facilitated by the circulatory system (blood vessels and the heart) and the lymphatic system. These transport systems help distribute essential nutrients, oxygen, hormones, and immune cells throughout the organism.
Do multicellular organism have a circulatory system?
Large animals require a circulatory system so that they are able to efficiently distribute materials throughout their body. The circulatory system consists of the heart, blood vessels, blood, lymph, lymph vessels, and associated organs such as the thymus, spleen, and liver. Various functions include: transport of nutrients from the digestive system and storage depots to each cell, transport of oxygen from respiratory structures, transport of metabolic wastes from cells to excretory organs, transport of hormones, helps to maintain fluid balance, distribute metabolic heat, maintain the approprate pH and help defend against invading microorganisms.

What 2 body systems do multicellular organisms use to move?
Multicellular organisms typically use the muscular and skeletal systems to move. The muscular system provides the force needed for movement, while the skeletal system provides structure and support for the muscles to act upon.
How do unicellular and multicellular organisms exchange materials?
Unicellular organisms exchange materials primarily through diffusion across their cell membrane, allowing nutrients, gases, and waste products to move in and out directly. In contrast, multicellular organisms utilize specialized systems, such as the circulatory system, to transport materials throughout their bodies, facilitating efficient exchange between cells and their environment. Additionally, multicellular organisms may rely on mechanisms like osmosis and active transport to regulate material exchange at a cellular level. This complexity allows for greater size and specialization in multicellular life.
Why do multicellular organism need a transport system like the blood and lymphatic system?
Multicellular organisms require transport systems like the blood and lymphatic systems to efficiently distribute nutrients, oxygen, and hormones to cells throughout the body, facilitating cellular metabolism and growth. These systems also play a crucial role in removing waste products and carbon dioxide, maintaining homeostasis. Additionally, the lymphatic system is essential for immune responses, helping to transport immune cells and remove pathogens. Overall, these systems ensure that all cells receive the necessary substances to function properly, which is vital for the organism's survival.
What do transport layer protocols use to identify the application needed to process data?
They don't do that. That is the role of the operating system.
