Cells function differently in unicellular and multicellular organisms, but in every organism, each cell has specialized cell structures, or organelles, of which there are many. These organelles are responsible for a variety of cellular functions, such as obtaining nutrients, producing energy, and making proteins. 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. Unicellular organisms include bacteria, protists, and yeast. For example, a paramecium is a slipper-shaped, unicellular organism found in pond water. It takes in food from the water and digests it in organelles known as food vacuoles. Nutrients from the food travel through the cytoplasm to the surrounding organelles, helping to keep the cell, and thus the organism, functioning. Multicellular organisms are composed of more than one cell, with groups of cells differentiating to take on specialized functions. In humans, cells differentiate early in development to become nerve cells, skin cells, muscle cells, blood cells, and other types of cells. One can easily observe the differences in these cells under a microscope. Their structure is related to their function, meaning each type of cell takes on a particular form in order to best serve its purpose. Nerve cells have appendages called dendrites and axons that connect with other nerve cells to move muscles, send signals to glands, or regis...

What is Tissues? Tissues are groups of similar cells that perform a specific function in the body of multicellular organisms. These cells are specialized and have a common structure and function. They work together to carry out specific tasks that are essential for the organism’s survival and functioning. There are four main types of tissues in multicellular organisms: epithelial tissue, connective tissue, muscle tissue, and nervous tissue.

A tissue is made of groups of cells that exist together to perform a specific function. The body of a complex multicellular organism consists of various types of tissue, each having its own distinct function. They provide structural and mechanical strength and enables the division of labour. In complex organisms, many tissues work together to form an organ and then an organ system.

In unicellular organisms, a single cell performs all the basic functions such as respiration, movement, excretion, digestion, etc. But in multicellular organisms, cells are grouped to form tissues. These tissues are specialised to carry out a particular function at a definite place in the body. For example, the muscle cells form muscular tissues which helps in movement, nerve cells form the nervous tissue which helps in transmission of messages. This is known as division of labour in multicellular organisms. It is because of this division of labour that multicellular organisms are able to perform all functions efficiently.

- [Instructor] In this video, we're gonna take a journey in life and we're gonna start with the smallest scale of life that is indisputably life, and that is the cell. Now, the reason why I qualified that a little bit is some people debate whether viruses are living or not, 'cause they have certain aspects. Viruses can reproduce, they do have genetic information but they need other living forms to reproduce, in particular they need other cells. But even though we imagined cells to be these very small microscopic things, they are in and of themselves almost an entire world, and we go into depth into that into other videos in Khan Academy. But the fact that every cell in your body, except for a few like red blood cells have all of your genetic information in there. All of those 3 billion base pairs of DNA that make you a human being in and of itself is mind-boggling. But then the fact that the cell specializes so that not all cells are the same even though they have that same genetic information, they somehow know what type of cell to be that's even more interesting. So we could start at the most basic building block in your body or really any organism's body and that's specialized cells. So what you're seeing here is a big cluster of neurons which are dyed here in the red, and I believe these blues show their actual nuclei where they have their genetic information. And then dyed in green, you have what are called neuroglia cells which are other types of cells that are insid...
