* Cell wall: This rigid, external layer composed primarily of cellulose, hemicellulose, and pectin provides structural support and protection to the plant cell. It's absent in animal cells.
* Plasmodesmata: These are small channels that connect the cytoplasm of adjacent plant cells, allowing for communication and transport of molecules. They are not found in animal cells.
While not directly part of the cell membrane, chloroplasts are another key difference. These organelles are responsible for photosynthesis and are present in plant cells but absent in animal cells.
Let me know if you have any other questions. 😊
