Depending on its role, each eukaryotic cell may specialize and include a varied percentage of each organelle type. Cell theory states that all living things consist of cells which are either prokaryotic or eukaryotic. Additional organelles may be found in different eukaryotic cells. The smooth ER serves as the primary location of lipid and steroid production. The mitochondria, which create the majority of the energy for the cell, are another key organelle. The rough ER extends from the nuclear membrane, is coated with ribosomes, and is where protein synthesis occurs. ER comes in two varieties: rough and smooth. The small size of prokaryotes allows ions and organic molecules that enter them to quickly spread to other parts of the cell. The endoplasmic reticulum is another membrane-bound organelle. At 0.15.0 m in diameter, prokaryotic cells are significantly smaller than eukaryotic cells, which have diameters ranging from 10100 m (Figure 2). Nuclear holes exist in the nuclear membrane and enable only certain substances to flow through. To complete this question, you have to compare and contrast prokaryotic and eukaryotic cells in terms of their organelle beigeminnow438 Module 2 introduces you to the living cell. The nuclear membrane, also known as the nuclear envelope, surrounds the nucleus and preserves the genetic material. Eukaryotic cells include a variety of membrane-bound structures known as organelles, which are specialized cellular components that perform certain cellular activities. A eukaryotic cell is a basis for every multicellular organism, including plants, animals, and humans, and certain unicellular organisms, such as protozoa.
