Verified step by step guidance
1
Begin by understanding the key differences between prokaryotic and eukaryotic cells. Prokaryotic cells are simpler and do not have a true nucleus or membrane-bound organelles, while eukaryotic cells do.
Recall that eukaryotic cells include plant and animal cells, both of which have a true nucleus and various membrane-bound organelles such as mitochondria, endoplasmic reticulum, and Golgi apparatus.
Identify that prokaryotic cells, such as bacteria, have genetic material that is not enclosed in a nucleus. Instead, their DNA is located in a region called the nucleoid.
Understand that prokaryotic cells lack organelles like mitochondria and chloroplasts, which are present in eukaryotic cells. This is a defining characteristic of prokaryotic cells.
Conclude that the type of cell that lacks a true nucleus and membrane-bound organelles is the prokaryotic cell, distinguishing it from eukaryotic cells, including plant and animal cells.
