hope it useful means mark as brainlist please.
Explanation:
1)An hen's egg is not a group of cells. It is a single cell. After it hatches to form a chick, the chick will have a group of cells. The egg of a hen represents a single cell and is big enough to be seen by the unaided eye.
2)The changing shape and the ability to form pseudopodia in every direction enables the Amoeba to move in all directions and engulf food from all the directions. The changing shape and the ability to form pseudopodia in every direction enables the Amoeba to move in all directions and engulf food from all the directions.
3)Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function. Multicellular organisms are composed of more than one cell, with groups of cells differentiating to take on specialized functions
4)All living things are composed of cells, and a group of cells form tissues. These tissues combine to form organs, and the organs form an organ-system. The tissues perform simpler tasks, whereas, the organs perform the complex functions of the body.
question number 3rd unicellular is is a single cell and multicellular is multicell so much cell
