Liquid endosperm in coconut is resulted due to-

Options

A. Karyokinesis followed by cytokinesis
B. Failure of karyokinesis followed by cytokinesis
C. Karyokinesis twice followed by single cytokinesis
D. karyokinesis is not followed by cytokinesis

Answer

To answer the question regarding the liquid endosperm in coconut, we can break down the explanation into clear steps:

### Step-by-Step Solution:

1. **Understanding Endosperm**: The endosperm is a tissue produced in the seeds of flowering plants, which provides nutrition to the developing embryo. In coconuts, the endosperm can be found in two forms: solid and liquid.

2. **Types of Endosperm Formation**: There are different types of endosperm formation, including cellular and nuclear endosperm. In the case of coconuts, the liquid endosperm is classified as a nuclear endosperm.

3. **Nuclear Endosperm Formation**: Nuclear endosperm is formed when the endosperm develops through a process where the nuclei divide without the formation of cell walls. This means that multiple nuclei can exist within a single cell, leading to a multi-nucleated condition.

4. **Caryokinesis**: The process involved here is called caryokinesis, which is the division of the nucleus. In the case of coconut endosperm, caryokinesis occurs, but cytokinesis (the division of the cytoplasm and the formation of cell walls) does not follow.

5. **Conclusion**: Therefore, the liquid endosperm in coconut is the result of caryokinesis occurring without cytokinesis, leading to a multi-nucleated structure that remains in a liquid state.

### Final Answer:
The liquid endosperm in coconut is resulted due to caryokinesis not being followed by cytokinesis.
