Answer 2

Answer:

Nuclear Organization:

On the basis of nuclear organization algae can be prokaryotic or eukaryotic. Cyanophyceae or blue green algae are prokaryotic in nature whereas all other classes of algae are eukaryotic. In prokaryotic e.g., Cyanophyceae—nucleus is not organized as nuclear membrane is absent.

DNA fibrils are free in nucleoplasm and are not associated with histones. Cell division by mitosis and meiosis is not found. Membrane bound cell organelle like chloroplast, mitochondria and ER are absent. Eukaryotic algae have well differentiated nucleus, mitochondria, chloroplast and endoplasmic reticulum in their cell structure.
