For all you e2020 students. The answer is lipids.
Common cell types found in both multicellular and single-celled organisms include: Epithelial cells, which form protective layers and coverings. Muscle cells, responsible for movement. Nerve cells, which transmit electrical signals.
Shells are protective coverings formed by marine creatures like mollusks and crustaceans. They are not alive and therefore cannot sell anything.
Epithelial cells would be best suited as a covering of an organ due to their protective function and ability to form tight barriers. They can be simple (one layer) or stratified (multiple layers) depending on the organ and its needs. Epithelial cells make up the outer layer of skin, the lining of blood vessels, and many other protective coverings in the body.
No, different types of human cells have unique shapes and structures based on their functions. Cheek cells are flat and irregularly shaped because they are protective epithelial cells. Other cells in the body, such as nerve cells or muscle cells, have different shapes that suit their specific roles.
Their protective coverings.
For all you e2020 students. The answer is lipids.
Plant cells have cell walls made of cellulose, chloroplasts for photosynthesis, and large central vacuoles for storage. These features are unique to plant cells and are not typically found in animal cells or other eukaryotic cells.
cell membrane
Cell membrane.
All cells have a protective covering called the cell membrane, also known as the plasma membrane. It surrounds the cell and regulates the passage of substances in and out of the cell.
yes ------------------- Actually, that is incorrect. Most plant cells have cell walls as a distinct type of structure. Other cells including bacteria and animal cells have a cell membrane or a plasma membrane as their outer boundary.
