What is amoeba and its function?
Answer: amoeba is a microscopic single-celled animal found in water bodies. It has a cell membrane,round nucleus,and many small bubble-like vacuoles in its cytoplasm. most amoebas have a contractile vacuoles which helps them to expel excess water from the cell. Amoeba constantly changes its position and shape.

Why are amoebas important?
Amoebae are also important for recycling nutrients in the soil. According to Maciver, when nutrients become available they are taken up by bacteria, that “effectively lock up all the nutrients in bacterial mass. ” When bacteria are consumed, nutrients are released back into the soil.

At what level of organization is amoeba?
In unicellular organisms, the single cell performs all life functions. Examples are Amoeba, Euglena Life can be organized into several different levels of function and complexity. These functional levels are: cells, tissues, organs, systems and organisms. Every living thing is made up of a cell or a number of cells.
What is an amoeba energy source?
The energy source for an amoeba is digested organic material from its environment. This can include smaller single-celled organisms or decaying…
What is the level of Organisation of blood?
For example, the heart and the blood vessels of the cardiovascular system circulate blood and transport oxygen and nutrients to all the body cells. Levels of Organization: Molecules form cells. Cells form tissues, and tissues form organs. Organs that fulfill related functions are called organ systems.
What level of organization is Hydra?
Yes, It is Tissue level of organization of Hydra.
What level of organization does an earthworm have?
Since the earthworm has regional specialization in its digestive system it is said to be at the organ system level of organization. The Hydra is at the tissue level of organization because its tissues have not become organized into larger functioning units (organs).
What level of organization is represented by Volvox?
Colonial Organisms Each Volvox, shown in Figure above, is a colonial organism. It is made up of between 1,000 to 3,000 photosynthetic algae that are grouped together into a hollow sphere. The sphere has a distinct front and back end.
What is the meaning of tissue level of organization?
The tissue level of organization consists of a group of cells that work together to accomplish one or more specific functions. The organ level of organization is when two or more tissues work together for a specific function.
What level of organization is the heart?
An organ system is a higher level of organization that consists of functionally related organs. Mammals have many organ systems. For instance, the circulatory system transports blood through the body and to and from the lungs; it includes organs such as the heart and blood vessels.
What are the levels of organization in the human body?
It is convenient to consider the structures of the body in terms of fundamental levels of organization that increase in complexity: subatomic particles, atoms, molecules, organelles, cells, tissues, organs, organ systems, organisms and biosphere (Figure 1.3).
What are the levels of organization?
An organism is made up of four levels of organization: cells, tissues, organs, and organ systems. These levels reduce complex anatomical structures into groups; this organization makes the components easier to understand.
What are the six levels of organization?
Summarizing: The major levels of organization in the body, from the simplest to the most complex are: atoms, molecules, organelles, cells, tissues, organs, organ systems, and the human organism.
What are the 5 levels of organization in the body?
These include the chemical, cellular, tissue, organ, organ system, and the organism level. Higher levels of organization are built from lower levels.
What are the 5 levels of organization?
