Mitotic Cell Division- Diagram, Definition and Process

Mitotic cell division structure

Mitotic cell division definition The mitotic cell division is an ordered sequence of events by which the nucleus of the cell duplicates and eventually the cell divides into two daughter cells. The cells of multicellular organisms undergo mitotic cell division for organism’s growth and repair or replacement of damaged cells. Mitotic cell division generates two … Read more

Diagram of Endoplasmic Reticulum – Definition, Types, Function and Structure

Endoplasmic Reticulum Definition Endoplasmic reticulum (ER) is the largest single membrane-bound organelle located in the cytoplasm of all eukaryotic cells. It is a flattened network of membranous tubules and it continues with the membrane of the nucleus. The membrane-enclosed compartment is called the ER lumen. Functionally, ER membrane is very dynamic and active. The endoplasmic … Read more

Diagram of Flagella – Definition, Types, Structure and Function

Structure of flagella

Flagella Definition Flagella are thread-like or lash-like microscopic bacterial surface appendages. The term “flagellum” means whip. It can be found on the cells of both prokaryotic and eukaryotic organisms. The flagellum is mainly assigned to cellular movements (locomotion, propel, motility, or swimming)  in liquid environments. In general, three types of thread-like appendages are found on … Read more

Labeled Prokaryotic Cell Diagram, Parts and Function

Structure of prokaryotic cell

Unicellular organisms of the domains Archaea and Bacteria are classified as prokaryotes. Prokaryotic cells lack membrane-bounded cellular organelles like lysosomes, nucleus, mitochondria, Golgi complex, and endoplasmic reticulum. Prokaryotic microorganisms are found to be more primitive than eukaryotes, which originated from them. Thus, these microorganisms are the earliest living forms, appeared on the earth four billion … Read more

Where is DNA located in a prokaryotic cell ?

Q. Where is DNA located in a prokaryotic cell? 1. Nucleus 2. Nucleolus 3. Nucleoid 4. Mitochondria   Answer: 3 (Nucleoid).   Explanation: Prokaryotes do not have a nucleus, nucleolus, and mitochondria which are cellular compartments in the eukaryotic cells that contain genetic material (DNA). The DNA in prokaryotes is located in a central region … Read more

Ta Os Rh in Periodic Table

Ta, Os, Rh are metals in the periodic table. Metal are chemical substances that share electrons to gain stability.
