S.No |
Characteristics |
Karyokinesis |
Cytokinesis |
1. | Definition |
It refers to the division of the nucleus containing. chromosomes equally into two daughter cells. |
It refers to the division of cytoplasm and organelles. the equally into two daughter cells. |
2. | Sequence | The first step of cell division or mitosis | The first step of cell division or mitosis |
3. | Complexity | More complex as it consists of 4 stages | Simpler |
4. | Dependency | Independent | Dependant on karyokinesis |
5. | Distribution | It distributes chromosomal material in daughter cells | It distributes cytoplasm and organelles in daughter cells |
6. | Events | Spindle formation and movement of chromosomes | Formation of cell plate or cleavage furrow |
7. | Speed | Slower | Faster |
8. | Constriction | Nuclear membrane constricts |
The cell membrane forms a cleavage furrow that splits into daughter cells |
9. | Types | Two types (symmetric and asymmetric) | No such types |
Difference Between Karyokinesis And Cytokinesis
very organism’s life begins with a single cell called a zygote. This zygote passes through numerous cell divisions, or mitosis, to develop into a multicellular organism. A cell divides into two stages: karyokinesis, which involves the division of the nucleus and cytokinesis- a division of the cytoplasm. This only means that during cell division, the chromosome-containing nucleus will split into two daughter cells before the cytoplasm and organelles are divided equally. The four stages of karyokinesis are prophase, metaphase, anaphase, and telophase. Cytokinesis denotes the division of the cytoplasm that occurs after these steps are finished. Animal and plant cells experience cytokinesis in diverse ways. The present article aims to take you through all the processes of karyokinesis and cytokinesis in a stepwise manner. Let’s start.
