What is the largest one celled organism?
Biologists used the world’s largest single-celled organism, an aquatic alga called Caulerpa taxifolia, to study the nature of structure and form in plants. It is a single cell that can grow to a length of six to twelve inches.
Why are large organisms multicellular?
Humans are multicellular. Multicellular organisms can be much larger and more complex. This is because the cells of the organism have specialised into many different types of cells such as nerve cells, blood cells, muscle cells all performing different functions.

Is human a multicellular organism?
As well as humans, plants, animals and some fungi and algae are multicellular. A multicellular organism is always eukaryote and so has cell nuclei. Humans are also multicellular.
Can multicellular organisms grow very large?
The area to volume ratio factor prevents single cells from becoming large in size while multicellular organisms grow and enlarge in size with cells dividing and increasing.
What keeps multicellular organisms alive?
For any multicellular organism to survive, different cells must work together. … Cells in multicellular organisms are specialized for a specific function. In animals, skin cells provide protec- tion, nerve cells carry signals, and muscle cells produce movement.
