Is algae prokaryotic or eukaryotic?

Hint: Algae are a group of large aquatic organisms which have the ability to conduct photosynthesis. Archaeplastida species come under the eukaryotic form. Archaeplastida types of species are land plants, red algae, green algae and glaucophytes. The organism which has a complete nucleus is called the eukaryotic organism.

Complete answer:
Algae have chloroplasts. Light energy is used to convert light energy into chemical energy. It performs photosynthesis by plastids. Algae has a nucleus inside it and all organelle in the cell is surrounded by the membrane. It contains double membrane bound organelles. They are chloroplast, nucleus and mitochondria. The two membranes which surround the nucleus are called the nuclear envelope.
Algae is the eukaryotic organism which contains leaf, chlorophyll, root and stem. By using this, these plants perform photosynthesis. It may or may not be unicellular or multicellular. Unicellular algae occur mostly in the plankton which live in the water.
Algae is called photosynthetic organisms. Algae is lacking in a well-defined body. It lives mostly in the moistures places. Reproduction is performed by sexual or asexual type.

Algae are the eukaryotic type of organism.

Note:
Blue green algae come under the prokaryotic types. And they are not coming under the algae types. Algae cannot share the ancestor characteristics so it doesn't possess any related characteristics of their ancestor. It is the free-living type of plants. Ulothrix, Porphyra, and Spirogyra are the common algae. Algae is used as the bio fuel. It produces green fuel and green jet fuel.
