Key Differences:
* Centrioles: These cylindrical structures play a vital role in cell division (specifically, in the formation of microtubules that pull chromosomes apart).
* Lysosomes: These membrane-bound sacs contain enzymes that break down waste materials, cellular debris, and engulfed pathogens.
* Cilia and Flagella: These hair-like projections aid in movement. Cilia are typically shorter and more numerous, while flagella are longer and fewer in number.
* Gap Junctions: These specialized channels allow for direct communication and the exchange of small molecules between adjacent animal cells.
Additional Points:
* Cell Wall: While plant cells have a rigid cell wall made of cellulose, animal cells lack this outer layer.
* Chloroplasts: These organelles, responsible for photosynthesis, are present in plant cells but absent in animal cells.
* Large Central Vacuole: Plant cells have a large central vacuole that stores water, nutrients, and waste products. Animal cells have smaller vacuoles, if any.
* Plasmodesmata: These channels connect the cytoplasm of adjacent plant cells, allowing for communication and transport of materials. Animal cells do not have plasmodesmata.
Remember: There are some exceptions to these general rules. For example, some plant cells (like sperm cells) do possess flagella.
