Why would a sponge be considered a colony of cells rather than a multicellular organism?

A sponge is a colony of cells because it is a group of cells living and working together. It would be a multicellular organism only if those cells were grouped together as a function

Compare and contrast multicellular and unicellular?
A specialized cell means simply that: it has a specific job in the body. Therefore, specialized cells will contain more of the parts it needs to carry out the specialized task. A unicellular organism has only one cell, which means that it has to carry out all functions of life in a single cell. Thus, it will have all the needed parts rather than specialized parts.
What are two benefits of multicellular organisms having some specialized cells rather then all the cells being the same?
Cells can specialize
Is a mutation more dangerous in a cell undergoing mitosis or meiosis?
Meiosis, because it occurs in gametes, which produce a new organism, rather than mitosis, which occurs in cells other than sex cells, and usually just causes the cell to die, and be replaced rather than grow into a mutated organism.
What is considered a functional system rather than an organ system?
Immune System.
What is organismal theory?
In plants, the organismal theory refers to the idea that during plant growth/evolution the original cell expanded into the whole organism. This is opposed to the cell theory that states that a cell multiplies into many cells with the original cell being equivalent to many. In this theory, the original cell is equivalent to the entire organism, with protoplasm just being subdivided and partitioned by cell walls (which are actually incomplete partitions because the protoplasms of adjacent cells are connected by plasmodesmata).
Does plankton have eyes?
No. That suggests something rather complicated (and multicellular) for a one celled organism.
How are cells in single cells and multicellular organisms similar?
Cells that are part of a multi-cellular organism typically have the same metabolic functions as single-celled organisms, however differences exist. Multicellular cells will have a specialized function, typically do not have to independently gather food and will express target genes selectively rather than all of the genes necessary for survival that a single-celled organism might express.
Do animals have animals have a nucleus?
Multicellular organisms do not have a nucleus; rather they have many nuclei. Most cells in an organism have a nucleus (with a few exceptions like red blood cells).
What is an organism that uses rather that produces?
An organism that uses rather than produces is called a comsumer

Why is volvox considered a protist rather than a metazoan animal?
Volvox is colonial organism as it lacks proper division of labour among cells, cells are not differentiated.
What are 2 advantages of being multicellular?
1. Any kind of abstract (rather than concrete) thinking. Single-celled organisms are apparently somehow aware of their immediate chemical environment (and will move away from toxic molecules, towards nutrient molecules [food], etc.), but that is all. 2. Specialized cells. Not every cell has to carry out every metabolic function in a multicellular organism.
Is a platypus multicellular?
Yes, they are an egg-laying mammal. A platypus is indeed an example of a monotreme. Though it is a mammal it lays eggs rather than giving birth.
A organism that uses rather than produces?
consumer.
