What is prokaryotic cell class 9 short answer?

The type of cells which do not have a well-defined nucleus and no membrane-bound organelles are known as prokaryotic cells. Organisms with prokaryotic cells are called prokaryotes and they are generally single-celled microorganisms. These organisms can be free-living or can be found in the gut of animals.

What are prokaryotic cell and eukaryotic cell class 9?

The defining characteristic feature that distinguishes between prokaryotic and eukaryotic cell is the nucleus. In prokaryotic cells the true nucleus is absent moreover membrane-bound organelles are present only in eukaryotic cells.

What does the word eukaryote mean quizlet?

Eukaryote comes from the Greek word for ‘true nucleus’ in a cell.

What are chromosomes class8?

A chromosome is a DNA molecule that consists of a part or all of the genetic material of an organism. The chromosome is present in the nucleus of each cell and it is packaged into thread-like structures. Structurally each chromosome is composed of DNA that is tightly coiled around special proteins called histones.

What is the difference between eukaryotic cells and prokaryotic cell class 8?

The cell wall is chemically complex in prokaryotes. For eukaryotes in plants and fungi the cell wall is present and chemically simpler.
