Consider the following statements: Prokaryotes do not have a nuclea...
Statement Analysis:
The given statements are:
1. Prokaryotes do not have a nuclear membrane.
2. Eukaryotes include only multicellular organisms.
Explanation:
1. Prokaryotes do not have a nuclear membrane.
- Prokaryotes are unicellular organisms that lack a well-defined nucleus and membrane-bound organelles.
- The genetic material in prokaryotes is present in the form of a single, circular DNA molecule located in the cytoplasm.
- Prokaryotes do not have a nuclear membrane that separates the genetic material from the cytoplasm.
- Hence, the statement is correct.
2. Eukaryotes include only multicellular organisms.
- Eukaryotes are organisms whose cells have a well-defined nucleus and membrane-bound organelles.
- Eukaryotes include both unicellular and multicellular organisms.
- Examples of unicellular eukaryotes include amoeba, paramecium, and yeast.
- Hence, the statement is incorrect.
Answer:
From the above explanation, it is clear that statement 1 is correct, but statement 2 is incorrect. Therefore, the correct answer is option A (1 only).

Consider the following statements: Prokaryotes do not have a nuclea...
Option a is correct
- Statement 1 is correct: The cells having nuclear material without nuclear membrane are termed prokaryotic cells. The organisms with these kinds of cells are called prokaryotes. Examples are bacteria and blue green algae. The nucleus of the bacterial cell is not well-organised like the cells of multicellular organisms.
- Statement 2 is incorrect: Eukaryotes, can be unicellular or multicellular and include animals, plants, fungi and protists. The cells having well-organised nucleus with a nuclear membrane are designated as eukaryotic cells.
- Similarities between Prokaryotic and Eukaryotic cells – Although prokaryotic and eukaryotic cells have many differences, they share some common features, including the following:
- DNA: Genetic coding that determines all the characteristics of living things.
- Cell (or plasma) membrane: Outer layer that separates the cell from the surrounding environment and acts as a selective barrier for incoming and outgoing materials.
- Cytoplasm: Jelly-like fluid within a cell that is composed primarily of water, salts and proteins.
- Ribosomes: Organelles that make proteins.
