Eukaryotic cells haveA Distinct nucleusB NucleolusC nuclear membrane D...
Introduction:
Eukaryotic cells are one of the two types of cells found in living organisms, the other being prokaryotic cells. They are more complex and evolved compared to prokaryotic cells. Eukaryotic cells are found in plants, animals, fungi, and protists.
Distinct Nucleus:
One of the defining features of eukaryotic cells is the presence of a distinct nucleus. The nucleus is a membrane-bound organelle that houses the cell's DNA. It acts as the control center of the cell, regulating gene expression and coordinating cellular activities. The nucleus is responsible for storing and transmitting genetic information to the next generation of cells. It is surrounded by a double-layered nuclear membrane, also known as the nuclear envelope.
Nucleolus:
Another characteristic feature of eukaryotic cells is the presence of a nucleolus. The nucleolus is a dense, spherical structure found within the nucleus. It is involved in the production and assembly of ribosomes, which are responsible for protein synthesis. The nucleolus contains ribosomal RNA (rRNA) and proteins.
Nuclear Membrane:
The nuclear membrane is a double-layered structure that surrounds the nucleus. It separates the contents of the nucleus from the rest of the cell's cytoplasm. The nuclear membrane is composed of two lipid bilayers, with nuclear pores that allow for the exchange of molecules between the nucleus and the cytoplasm. It also provides structural support and protection to the nucleus.
Nucleoid:
The nucleoid is a region found in prokaryotic cells, not eukaryotic cells. Prokaryotic cells, such as bacteria, lack a distinct nucleus. Instead, their genetic material is located in a region called the nucleoid. The nucleoid is not surrounded by a membrane and is not as organized as the nucleus in eukaryotic cells.
Correct Answer:
Therefore, the correct answer is option C, which states that (a), (b), and (c) are correct. Eukaryotic cells have a distinct nucleus, nucleolus, and nuclear membrane. The nucleoid is a feature specific to prokaryotic cells and is not present in eukaryotic cells.
