false.
initially at the embryo stage, yes, when they are stem cells, and have the potential to differentiate in any kind of cell.But during differentiation they acquire specific receptors on their membranes, and become specialised to perform a function.
But, if talking about the genotype of each cell, i.e. the genetic make-up, they are the same.though certain genes are expressed in some cells, and the others in other cells.
thus different cells are present, which make up different tissues and organs, for performing the same or related function.

FALSE. at the beginning of embryonic development all cell are alike--they are called stem cells.. the only problem is that, to form a multicellular living being, the cells have to undergo specialization in which the features of these cell change to fit their job such as neuron cells are different than either muscle or blood cell so the cells arent just one kind, the body is too complex for a simple structure and requires mor than one type to carry out all the body's needs.

It depends on what you mean by "the same kind of cell". When an embryo developes, initially all cells are the same. As the embryo grows the cells become specialized. Some become muscle cells, some brain cells etc. etc. This is the reason stem cells are so important; they have the ability to become any kind of cell in the body.

False. Cells are different in the brain, bones, muscles, organs, blood, hair, etc. They are different because they have unique functions. The only similiarity is that each cell contains a nucleus and genetic material enclosed by a membrane.

False. Every organ has different cells, there are bone cells, muscle cells, brain cells, everything in your body has its own cells. I hope this helps.

They all start the same, and are called stem cells. After each cell differentiates, they become different and acquire the jobs they were meant to do. It depends on which genes are turned on and off during the differentiation.

False. There are heart cells, liver cells, skin cells, eye cells. If they were all the same, we'd all be one big blob that did nothing.
