Multicellular.
approximately 100 trillion cells are in the human body There are many different cells.
Yes it is true. Mammalian (e.g. human) red blood cells have no nuclei. This enables them to be smaller, allowing them to carry more oxygen around the body.
No. Both plant and animal cells are eukaryote. This means they both have a membrane bound nucleus and many membrane bound organelles.
Yes, flatworms(platyhelminthes) are multi-celluar organisms. Even the most primitive forms of platyhelminthes consist of several thousand cells.
By definition, a prokaryote is a single celled organism. An onion is made up of many cells, hence, it is a eukaryote.
Eukaryote cells come in many different sizes but they are usually bigger than prokaryote cells.
A mushroom will consist of millions to billions of cells.
people
the brain consist of about 2 billion cells or more.
They have 1, because they are Prokaryote. http://en.wikipedia.org/wiki/Prokaryotic
Basically because bacteria are prokaryote and protozoa ( protists ) are eukaryote. Prokaryote cells are simple cell of no nucleus or membrane bound organelles. Eukaryote cells have their genetic material in a membrane bound nucleus and have many membrane bound organelles.
A 12 volt automotive battery has six cells.

100 trillion
about 50 or 60 trillion (4 real !! )
