Specialized Cells
Animal Cells Plant Cells Muscle Cells Epithelial/Dermal Red Blood Epidermal Meristematic Ground Vascular Muscle cells are in your body to allow your body to move. Muscle cells can be cardiac, skeletal, or smooth muscles. Skeletal muscles are voluntary, like the ones to move your legs. Cardiac and smooth muscles are involuntary, like the muscles that keep your heart pumping. Muscle cells have a plasma membrane around each muscle fiber. They have tunnel-like extensions in the middle and a cytoplasm. They often have many nuclei and tons of mitochondria. They also have sarcoplasmic reticulum, similar to smooth endoplasmic reticulum. An example of a smooth muscle cell, Epithelial cells join together to form tissue, such as the one that makes up the outer surface of the body. This causes the shape of the body and also offers protection. This cell has a nucleus, cytoplasm, and a cell membrane in it. Red blood cells are in your body to carry oxygen to all the different parts of the body and remove carbon dioxide. Red blood cells don't have a nucleus, mitochondria, or ER. Instead, they have enzymes to get energy and hemoglobin to control the cell. Epidermal makes up the outer layer of plants, such as on the leaves. They preform actions such as preventing water loss and regulating gas exchanging. The structure of epidermal is A close up of red blood cells Meristematic cells are unique plant cells that give it the ability to replace damaged parts. Meristematic cells can adapt to function the same as any other cells in the plant, allowing it to regenerate damaged parts. The cells in meristematic tissue will eventually become either ground tissue, vascular tissue, or dermal tissue. Ground cells are responsible for storing carbohydrates. They also make most of the leaves, stems, and roots. They are made with thin walls, many chloroplasts, and large vacuoles. Vascular cells bind together to form vascular tissues, which contain xylem. This allows for water and minerals to be transferred through the plant to where they need to go. They are made up of xylem and phloem. Ground
