Here's why:
* Eukaryotic cells: Fish cells, like all animal cells, are eukaryotic. This means they have a membrane-bound nucleus containing their genetic material (DNA) and various other membrane-bound organelles that perform specific functions.
* Nucleus: The nucleus is the control center of the cell, containing the DNA that dictates all cellular activities.
* Organelles: Fish cells have the same essential organelles found in other eukaryotic cells, including:
* Mitochondria: Powerhouses of the cell, producing energy (ATP).
* Endoplasmic reticulum (ER): Network of membranes involved in protein synthesis and lipid metabolism.
* Golgi apparatus: Processes and packages proteins for transport.
* Lysosomes: Contain enzymes for breaking down waste materials.
* Ribosomes: Sites of protein synthesis.
Therefore, fish cells are complex and highly organized, just like any other animal cell.
