by allowing them to diffuse through the cell membrane
Phagocytosis allows single-celled organisms to obtain nutrients by engulfing and digesting particles like bacteria or other small organisms. This process helps them to acquire essential nutrients for growth, reproduction, and energy production, ultimately promoting their survival. Additionally, phagocytosis can also aid in defense by allowing the organism to consume potential threats or harmful particles in their environment.
Humans have a complex circulatory system to efficiently transport oxygen, nutrients, hormones, and waste products to and from cells throughout the body. Amoebas, being single-celled organisms, can rely on simple diffusion to exchange gases and nutrients with their environment due to their small size and surface area.
In single-celled organisms, such as bacteria or protists, absorption occurs directly through the cell membrane. The cell membrane allows for the passage of oxygen, nutrients, and other molecules into the cell through processes like diffusion or active transport. This direct contact with the external environment allows single-celled organisms to efficiently obtain the necessary resources for survival and growth.
Single-celled organisms lack the internal structures necessary to support larger size. Diffusion is inefficient over long distances in larger cells, limiting their ability to efficiently exchange nutrients and waste. In addition, larger size would require more complex structures for movement and support, which would be energetically costly for single-celled organisms.
The surface area-to-volume ratio limits the size of single-celled organisms. As a cell grows larger, its volume increases at a greater rate than its surface area, making it harder to exchange nutrients and waste efficiently. This constraint impacts the cell's ability to maintain proper functioning and limits its size.
no
Yes, living organisms that depend on diffusion for processes like respiration or nutrient exchange include single-celled organisms like protozoa, small invertebrates like flatworms and roundworms, aquatic organisms like sponges, and even some small insects. Diffusion allows them to exchange gases, nutrients, and waste products with their environment, essential for their survival.
Single cell organisms do not have a circulatory system like humans because they are single-celled and do not have complex internal structures. Instead, they rely on simple diffusion for the exchange of gases and nutrients.

One celled organisms are called unicellular organisms.

In addition, larger size would require more complex structures for movement and support, which would be energetically costly for single-celled organisms.
The five main kingdoms in nature are: Animalia (organisms with complex cells and tissues), Plantae (organisms that photosynthesize), Fungi (organisms that absorb nutrients), Protista (mostly single-celled organisms), and Monera (prokaryotic organisms).
The surface area-to-volume ratio limits the size of single-celled organisms. As a cell grows larger, its volume increases at a greater rate than its surface area, making it harder to exchange nutrients and waste efficiently. This constraint impacts the cell's ability to maintain proper functioning and limits its size.
cause many celled organisms grow faster
Easy!! diffusion.. because single celled organisms have a large surface area to volume ratio meaning that there exchange surface is large enough to allow efficient diffusion fast enough to keep the cells alive (1 cell.. lol ). they also aren't very active they can rely on diffusion alone to take up water and other important solutes.. Diffusion through osmosis occurs in single celled organisms when they have a lower water potential inside the cell than outside so water flows into the cell (down the concentration gradient) via a partially permeable membrane. hope that helped from Kate Gibson 16
