Algae Algae (singular: alga) are photosynthetic, eukaryotic organisms that do not develop multicellular sex organs Algae can be unicellular, or they may be large, multicellular organisms Algae can occur in salt or fresh waters, or on the surfaces of moist soil or rocks The multicellular algae develop specialized tissues, but they lack the true stems, leaves, or roots of the more complex
- Green Algae | Encyclopedia. com
green algae Large group of marine and freshwater algae (phylum Chlorophyta) They are distinct from other algae by virtue of possessing cup-shaped chloroplasts that contain chlorophyll b, and by producing cells with flagella at some stage in their lives Green algae range in size from microscopic single-cell types to large, complex seaweeds
- Cyanobacteria - Encyclopedia. com
Cyanobacteria Cyanobacteria (blue-green algae [1]) are microorganisms that structurally resemble bacteria (they lack a nucleus and organelles ) However, unlike other bacteria, cyanobacteria contain chlorophyll a and conduct oxygenic photosynthesis
- Blue-Green Algae - Encyclopedia. com
Blue- green algae Blue- green algae are actually a type of bacteria that is known as cyanobacteria In their aquatic habitat, cyanobacteria are equipped to use the sun's energy to manufacture their own food through photosynthesis The moniker blue-green algae came about because of the color, which was a by-product of the photosynthetic activity of the microbes, and their discovery as a algal
- Dinoflagellata | Encyclopedia. com
dinoflagellates A division (Dinoflagellata) of protists that are heterotrophs but closely allied to brown algae and diatoms (they are sometimes classified as algae) Many have brown or yellow chromoplasts containing xanthophyll and chlorophylls a and c; others are colourless Typically, dinoflagellates have two flagella, one propelling water to the rear and providing forward motion, attached
- Chlorophyll - Encyclopedia. com
Chlorophyll (KLOR-uh-fill) is the pigment that gives plants, algae, and cyanobacteria their green color The name comes from a combination of two Greek words, chloros, meaning "green" and phyllon, meaning "leaf " Chlorophyll is the substance that enables plants to create their own food through photosynthesis At least five forms of chlorophyll
- Protista - Encyclopedia. com
Protista Background Classification Protozoa Algae Slime molds and water molds Disease-causing protists Beneficial protists Resources The kingdom Protista is the most diverse of all of the eukaryotic kingdoms It is certainly not monophyletic and its members really only share the fact that they have a simple structure, without any obvious tissues or organs There are more than 200,000 known
- Chlorophyta - Encyclopedia. com
Chlorophyta (green algae) Division of algae which are typically green in colour In common with higher land plants, green algae include chlorophylls a and b among their principal pigments, have cellulose as the main constituent of cell walls, and form food reserves of starch
