Yes, it comes from mitochondria which have ds circular dna, which inherits from only from maternal cytoplasm because during fusion of sperm and egg, sperm doesn't bring any cytoplasmic DNA

Mitochondria and Cytoplasmic Particles are responsible for cytoplasmic inheritance.

Mitochondria and their Role in Cytoplasmic Inheritance:
- Mitochondria are organelles found in the cytoplasm of eukaryotic cells and are responsible for energy production through oxidative phosphorylation.
- They carry their own set of genetic material in the form of mitochondrial DNA (mtDNA), which is separate from the nuclear DNA.
- Unlike nuclear DNA, mtDNA is inherited exclusively from the mother.
- During fertilization, the sperm contributes only nuclear DNA to the zygote, while the egg contributes both nuclear DNA and mtDNA.
- Therefore, offspring inherit their mtDNA solely from their mother.
- Mutations in mtDNA can lead to a variety of inherited disorders, including mitochondrial diseases.

Cytoplasmic Particles and their Role in Cytoplasmic Inheritance:
- Cytoplasmic particles, also known as cytoplasmic factors or cytoplasmic determinants, are molecules or structures present in the cytoplasm of cells.
- They play a crucial role in the development and differentiation of cells.
- Cytoplasmic inheritance refers to the inheritance of traits or characteristics determined by these cytoplasmic particles.
- These particles can influence various cellular processes, such as cell division, cell fate determination, and gene expression.
- In some cases, cytoplasmic particles can be inherited independently of nuclear DNA.
- For example, in certain species of plants, the inheritance of chloroplasts (organelles responsible for photosynthesis) is determined by cytoplasmic particles.
- Similarly, in some animals, such as fruit flies, the inheritance of eye color is determined by cytoplasmic particles.

Importance of Cilia and Cell Wall:
- Cilia are hair-like structures found on the surface of many cells.
- They play a role in cell movement, the movement of fluids across cell surfaces, and sensory functions.
- However, they are not directly involved in cytoplasmic inheritance.
- The cell wall is a rigid layer found in plant cells, fungi, and some bacteria.
- It provides structural support and protection to the cell, but it is not involved in cytoplasmic inheritance.

In conclusion, cytoplasmic inheritance is primarily due to the presence of mitochondria and cytoplasmic particles. Mitochondria contribute their own genetic material (mtDNA) to the offspring, while cytoplasmic particles can determine specific traits or characteristics that are inherited independently of nuclear DNA. Cilia and cell walls, on the other hand, do not play a direct role in cytoplasmic inheritance.
