what are the characteristics of green algae?
302414
Green algae have chloroplasts that contain chlorophyll a and b, giving them a bright green color, as well as the accessory pigments beta carotene (red-orange) and xanthophylls (yellow) in stacked thylakoids. The cell walls of green algae usually contain cellulose, and they store carbohydrate in the form of starch.

Like other algae, green algae serve as an important food source for herbivorous marine life, such as fish, crustaceans, and gastropods, including sea snails. Humans use green algae as food, too. ... The pigment beta carotene, found in green algae, is used as a food coloring.

Chlorophyll and accessory pigments allow algae to harvest and use the energy from sunlight. What are the distinguishing features of the major phyla of unicellular algae ("plantlike protists") ? * "Euglenophytes" are "plantlike" protists that have 2 flagella but no cell wall.

Ecological and commercial importance. Algae form organic food molecules from carbon dioxide and water through the process of photosynthesis, in which they capture energy from sunlight.

General Characteristics of Fungi: No chlorophyll – non photosynthetic. Most multicellular (hyphae) – some unicellular (yeast) Non-motile. Cell walls made of chitin (kite-in) instead of cellulose like that of a plant.

It is believed that land plants are the most closely related to green algae, more specifically, a group of green algae referred to as charophyceans.

As mentioned before, green water is caused by single-celled plant organisms called algae. This organism typically occurs when there is an imbalance (high amount) of nitrates and phosphate levels in pond water providing algae with the nutrients to grow and in perfect conditions, thrive!

Defining cyanobacteria characteristics are a tolerance of extreme conditions and an ability to exist without vitamins. They use phosphorus, iron and other micronutrients, and ammonia or nitrate as a nitrogen supply. Some types of cyanobacteria are filamentous and don't need sunlight.

The cyanobacteria are also called the blue-green algae. ... Some of the cyanobacteria can be heterotrophs as well. The main difference between green algae and cyanobacteria is that green algae contain chloroplasts whereas cyanobacteria do not contain chloroplasts in their cells.

Organism which exhibits characteristics of both plants and animals is euglena. All live in water, and move by means of a flagellum. This is an animal characteristic. Most have chloroplasts, which are characteristic of algae and plants.

Seaweeds are a group of algae, and have some special characteristics viz. macroscopic, multi-cellular, benthic, and marine. ... All the seaweed species are autotrophic, whereas some algal species rely on other external food materials. Algae inhabit both freshwater and marine waters, while seaweeds inhabit only seawaters.
