Or what the difference is, for that matter? If not, then this blog post will help clear up the confusion. While they are both important parts of our body, they serve different purposes. Cells make up tissue and our bones, muscles, organs, and other structures in the body. Tissues are made up of many cells that work together to form particular shapes or functions, such as skin or cartilage. If you do cells vs. tissue, you will get to know that both are equally important for making up organisms. What Is Cell? Cells are the basic units of life. We have trillions of cells in our body, and each one is different. For example, brain cells don’t look like skin cells or muscle cells. Cells can be differentiated by their shapes and what they do for the organism. You can also differentiate between cells and tissues with their shape. Brain cells will not function as blood cells because they have specialized features that will not allow them to do so. For a better understanding of cells, take a look at the diagram of a cell to understand the structure and functions of the Cell The first illustration shows three types of human cells with different shapes and functions. The top is a skin cell because its shape resembles that of an oval or egg. This type of cell can be found on our outer layer of skin and can help regulate our body temperature by releasing sweat. The middle cell is a muscle cell because it looks more like an oval with two lines on its side that resemble muscles. This type of cell helps maintain posture, tone, and movement within our bodies and generates heat for us through its activity. Finally, the bottom cell is a brain cell because it has an elongated, spindle-shaped shape. Brain cells can regulate our behaviors and responses to stimuli as well as send signals throughout the body through neurotransmitters like serotonin or dopamine. This diagram of cells is a clear depiction of the cells. What Is Tissue? Tissues are made up of many cells that work together to form particular shapes or functions. Skin, bone, cartilage, and muscle are examples of tissues with different cell types to carry out their function. Much like cells, tissues also vary in size and shape. Cartilage is a tough but flexible tissue that covers our joints to allow them to move freely without causing damage or inflammation. The skin, on the other hand, is more elastic with an elastic layer of fat underneath it for insulation purposes. The following tissue diagram illustrates four types of tissues found within our body: The first illustration at the top is a cross-section or connective of skin tissue found on our outer layer. The cells in this type of tissue are very closely packed together, and they produce oils that help keep us hydrated, lubricate joints, and regulate temperature. This particular graph also shows how different layers make up the skin, such as hair follicles, sweat glands (which release perspiration), and the epidermis. The second illustration is a cross-section of cartilage tissue found in our joints to help make them more flexible and reduce inflammation when they’re used often or too much. While this type of tissue may appear soft because it contains fluid-filled spaces between its cells, it is actually very tough and can withstand a lot of pressure. The third illustration shows a cross-section of muscle tissue found in our body to help with posture, movement, and generating heat. Muscle cells are long and thin, which allows them to contract quickly when stimulated by the nervous system or hormones like adrenaline. They contain many mitochondria arranged as seen in the diagram below: The last illustration shows a cross-section of nervous tissue found throughout the entire body. This type of tissue is mostly made up of cell bodies containing dendrites and axons that extend outward to other cells to carry messages from one place to another. Interesting Facts About Cells And Tissues Skin cells produce oils that help keep us hydrated, lubricate joints, and regulate temperature.Muscle cells are long and thin, which allows them to contract quickly when stimulated by the nervous system or hormones like adrenaline.Brain cells can regulate our behaviors and responses to stimuli as well as send signals throughout the body through neurotransmitters like serotonin or dopamine.Cartilage is a tough but flexible tissue that covers our joints to allow them to move freely without causing damage or inflammation. It is considered as the major and most basic criteria to differentiate between cells and tissues.On the other hand, the skin is more elastic with an elastic layer of fat underneath it for insulation purposes.Connective tissue helps to hold our cells together and is a major component of organs like the heart, lungs, liver, and kidneys.Cells need oxygen to create ATP, which gives them energy in order for them to do their jobs properly within the body’s cells. Frequently Asked Questions How many types of cells are there? When you learn about what a cell is, you need to know how many types of cells are present in your body. There are billions of different cell types within our body. These include brain, skin, and muscle cells, to name a few, with each type performing a specific function that is crucial for keeping us healthy. What does ATP stand for? ATP stands for Adenosine Triphosphate, which is a molecule that provides energy for the body’s cells to do their jobs. What are some characteristics of connective tissue? Connective issues contain many different types of proteins like collagen and elastin, which help them hold our cells together while also being a major component in organs such as the heart, lungs, liver, and kidneys.
