Chlorophyta: Class, Important Features and Orders.
Chlorophyta are a division of green algae. It includes about 7,000 species of mostly aquatic photosynthetic eukaryote organisms. Like the land plants, green algae contain chlorophylls a and b, and store food as starch in their plastids.Most species are flagellate in at least one stage of their life cycle. They are related to the Charophyceae (also called Charophyta) and land plants.
Green algae is a very large group of algae and does not have one specific class that it belongs to. Green algae is divided into two main divisions, chlorophyta and charophyta. Within these.
Chlorophyta is the largest of the eight divisions of algae. Members of the Chlorophyta, or grass-green algae are similar to higher plants being characterized by a well-defined nucleus, photosynthetic pigments localized in chloroplastids in which usually pyrenoids are present, the food reserve is commonly stored as starch, and the possession of cell walls in which cellulose is usually a clearly.
Introduction to the Chlorophyceae fresh-water green algae. The Chlorophyceae are a large and important group of freshwater green algae. They include some of the most common species, as well as many members that are important both ecologically and scientifically. There are approximately 350 genera and 2650 living species of chlorophyceans. They come in a wide variety of shapes and forms.
Green algae are any of the species of algae that are classified under the taxonomic division chlorophyta. Their name comes from two Greek words, chloros (green) and phyto (plant). They are an incredibly diverse division with many differences in physical appearance and structure. The division contains nearly 12,000 different species, making it one of the largest groups of algae.
Green algae range in size from microscopic to large plants, and can be single celled, colonial, or filamentous. Some of the single celled and colonial green algae have small tails or “flagella” attached to each cell, which they use to swim. However many green algae are non-motile. Green algae may be either planktonic or attached. They show the greatest diversity of shapes, sizes and.
Cyanobacteria or blue-green algae are single-celled organisms (prokaryotes) whose existence dates back nearly four billion years, placing it among the earth oldest and most primitive forms of life. Cyanobacteria thrive in almost every environment like hot springs, salt marshes, moist soils etc. They are found most frequently in freshwater lakes and rivers throughout the world, but variants.
