In flatworms, which are acoelomates, nutrients are absorbed directly from the environment through their moist skin and distributed to cells via diffusion. Their bodies are relatively thin, allowing for efficient nutrient exchange without specialized circulatory systems. The gastrovascular cavity also plays a role, as it helps in the digestion and distribution of nutrients throughout the body. Overall, the flatworm's simple body plan facilitates direct nutrient access to all cells.
What else can I help you with?
What are the examples of acoelomate animals?
Flatworms, such as tapeworms and planarians, are examples of acoelomate animals. These animals lack a true body cavity called a coelom and have a solid body structure instead.
What type of animals have no body cavity?
Lower phyla in the animal kingdom such as Cnidarians, Porifera, and Ctenophora.
Do flatworms have no coelom?
flatworms are the only triploblastic organisms that lack a coelom
What structures does a flatworm expel solid waste?
Flatworms expel solid waste through a structure called the pharynx, which is a muscular tube that can extend out of their bodies. They use this pharynx to ingest food and also to expel undigested material. Additionally, flatworms possess a network of excretory canals that help in the removal of waste products, primarily through specialized cells called flame cells. These adaptations allow them to efficiently manage waste despite their simple body plan.
Explain how bone cells embedded in a solid ground substance obtain nutrients and eliminate waste?
Osteocytes are mature bone cells surrounded by matrix which solid bone cell ground substances attach to. Bone cells are in the proximity of blood vessels, just like any other cell in the body. Bones only have cells in their growth areas and in the bone marrow, where blood cells are also produced.
What are the solid and liquid component blood?
The solid components of blood are red blood cells, white blood cells, and platelets. The liquid component is called plasma, which carries these cells, nutrients, hormones, and waste products throughout the body.
What are solid substances that are nutrients?
solid subtanses are the solid stuff
What is A culture of living cells includes a solution called a?
A culture of living cells includes a solution called a "culture medium." This medium provides the necessary nutrients, vitamins, and minerals that cells need to grow and proliferate. It can be either liquid or solid, with agar used to create solid media. The composition of the culture medium can vary depending on the type of cells being cultured.
Flatworms have layers of tissue that surround the gut and organs in one solid body they are?
Flatworms are triploblastic organisms, meaning they have three germ layers (ectoderm, mesoderm, endoderm) that give rise to different tissues in their body. This allows them to have specialized structures like muscles and nerves. They have a solid body shape, lacking a body cavity or coelom.
What state of matter is beets?
Beets are a solid state of matter. They consist of cells that contain water, nutrients, and pigments, giving them their characteristic color and texture. In their natural form, beets are typically consumed cooked or raw, both of which maintain their solid state.
What are the different types of waste and how are they removed by plants by humans and by flatworms?
Waste can be categorized into several types, including solid waste, liquid waste, and gaseous waste. Plants primarily remove waste through processes like transpiration, where excess water and some metabolic byproducts are released into the atmosphere. Humans eliminate waste through various systems, including urinary and digestive systems, which expel solid and liquid waste. Flatworms, being simpler organisms, excrete waste through structures called flame cells that filter and expel waste products from their bodies.
What blood cells make up the solid part of the blood?
Blood has red cells and white cells, but I'm not sure what is meant by 'solid part'.
