Here's why:
* Both plant and animal cells share the basic organelles: These include the nucleus, ribosomes, endoplasmic reticulum, Golgi apparatus, mitochondria, and lysosomes.
* Plant cells have additional organelles: These include chloroplasts, cell walls, and vacuoles.
Let's break down why mouse cells don't have chloroplasts, cell walls, or large central vacuoles:
* Chloroplasts: These organelles are responsible for photosynthesis, the process of converting light energy into chemical energy. Mouse cells are heterotrophic, meaning they obtain energy by consuming other organisms, so they don't need chloroplasts.
* Cell Walls: These rigid structures provide support and protection to plant cells. Animal cells have flexible cell membranes that allow for movement and flexibility.
* Large Central Vacuole: Plant cells have a large central vacuole that helps with storage, water regulation, and maintaining cell turgor pressure. While animal cells have smaller vacuoles, they don't have a large central one like plant cells.
In summary, while plant cells have some unique organelles, all the organelles found in lettuce cells are also present in mouse cells.
