Algae have conventionally been regarded as simple plants within the study of botany, the "plant-like" character from their photosynthetic quality, their "simple" character being their lack of vascular tissue.
Algae problems are a major concern to pond, lake, and watergarden owners. ... Not all aquatic plants are algae. Also, not all algae is created equal when it ...

Definition of algae :
Unicellular or multicellular photosynthetic eukaryotes that generally lack roots, stems, leaves, conducting vessels, and complex sex organs.
In five kingdom scheme of classification, the algae, together with the protozoa, belong to Kingdom Protista. They are distinct from the protozoa by being photosynthetic.
Algae: A heterogeneous group of aquatic, unicellular, colonial or multicellular, eukaryotic and photosynthetic organisms. They belong to the Kingdom Protista and include the multicellular red (rhodophyte), green and brown (kelp) algae.

Red Algae
The red algae are almost exclusively marine.
Some are unicellular but most are multicellular.
Approximately 4000 species have been identified.
They are photosynthetic using chlorophyll a.
brown algae Multicellular protistans placed in the Division Phaeophyta, includes kelp.

Plants, some algae, and some bacteria obtain their energy from light. The light energy is used to bond molecules of carbon dioxide together to form sugar (glucose). The energy is stored in glucose. This process is called photosynthesis.

Green plants and algae also use both photosystems. In these organisms, photosynthesis occurs in organelles (membrane bound structures within the cell) called chloroplasts.

An organism whose cells possess a nucleus and other membrane-bound vesicles, including all members of the protist, fungi, plant and animal kingdoms; and excluding viruses, bacteria, and blue-green algae. See Prokaryote. Evolution.
algae and slime molds). Some people put the algae in the Plant kingdom and the slime molds in the Kingdom Fungi. We will put both groups in the kingdom Protista but acknowledge that they are on the "borderline.
It's all about a fungus and some algae. That's it. Lichen is two organisms working together. When you read about fungi we talked about hyphae. Hyphae are strands of the fungi that form a mesh as they grow.
Thought to have evolved from the green algae, plants have been around since the early Paleozoic era, more than 500 million years ago. The earliest fossil evidence of land plants dates to the Ordovician Period (505 to 438 million years ago).
In 1995 Peter Steinberg of the University of New South Wales, Australia, realized that the fronds of a red algae growing in Botany Bay are rarely covered with biofilms.
All plants, algae, and cyanobacteria which photosynthesize contain chlorophyll "a". A second kind of chlorophyll is chlorophyll "b", which occurs only in "green algae" and in the plants.
Diatoms are very common unicellular algae that have a characteristic cell wall of silica. They exhibit a wide variety of shapes, some quite exquisite.

The Plantae Kingdom is made up of all the plants that you see each day. Most plants are multi-cellular, meaning that they consist of many cells. Different types of plants include trees, grass, flowers, and some types of algae.
Phycobilisome A large assembly of phycobiliproteins, which contain the light-absorbing compound bilin, that harvests light for organisms, such as red algae and cyanobacteria, living at a depth of a meter or more in seawater.
These proteins are considered part of the detoxification pathway used by eukaryotes (animals, plants, algae, and fungi) to rid themselves of toxins.
Now, there are different plants and different microbes, such as bacteria and algae, which have different protective mechanisms.
