What is an angiosperm

It is a plant that has flowers and produces seeds enclosed within a carpel. The angiosperms are a large group and include herbaceous plants, shrubs, grasses, and most trees.

Angiosperms (a plant whose ovules are enclosed in an ovary) are commonly referred to as "flowering plants", as opposed to gymnosperms, or "cone bearing plants."

Angiosperms form a phylum, the phylum Anthophyta. Angiosperms are also called anthophytes or magnoliophytes. The sporophyte is dominant and the gametophyte is the most reduced of all plants. There are so far more than 300,000 far named angiosperms. Angiosperms evolved in the Cretaceous. Many have close-bound mutualisms with pollinating insects.

Angiosperms are divided into monocotyledons and eudicotyledons (dicotyledons)

How is bacteria and virus dfferent

Viruses cannot divide or grow on their own; they can only divide and multiply when they infect a host organism. Viruses that infect bacteria are known as bacteriophages.

Bacteria can divide on their own and multiply; they have their own intracellular mechanisms for generating energy from substrates such as sugar (or other).

In essence bacteria are independent living organisms where as viruses are not.
