What are seaweeds?

• Seaweed is not a plant they are simple a construction but they lack vascular tissues.

• Seaweed is also photosynthetic.

• It can be maintained alive for significant periods of time, they could be preserved wet or dry.

taxonomy• People treat algae as a

subkingdom under the whittaker 5-kingdoms system of classification.

• Algaes classification is very unstable.

• Algae belongs to the same order as land plants.

Algae's Anatomy

I. Algae do not have true roots, stems, leaves, vascular tissue and have simple reproductive structures.

Algae’s physiology I. Algae triples in volume

everyday.II. Algae creates exotoxins, a

toxin produced during growth of a microorganism and released into the surrounding area affecting the marine life.

III. Algae’s is a photosynthetic organism that takes in sun energy.

IV. Algae also takes in co2 and transforms it back into oxygen.

Algae’s ecology

• Algae utilizes light energy in the process of reducing CO2 to oxidation state of cellular carbon.

• It is also used to create biofuels

The use of Algae• Algae is being used to create new bio-fuels.• Scientist have yet more research to do, to make everything possible! • Another interesting fact is some lipsticks are made of algae.

You can find algae almost everywhere!

• You can find algae in most body’s of water.

• In ponds • Streams• Lakes • Rivers• Oceans and on the

beach

Chlorophyta (green)

Ulva is a thin flat green alga growing from a discoid holdfast, and it can grow 18cm long and 30cm wide.

Chaetomorpha lives in many parts of the ocean, its growth form reassembles a corkscrew of string an looks like a piece of steel wool or pasta.

Enteromorpha is a long green alga that grows up to 15cm tall, its mostly tubular and hollow .

Spirogyra is a spiral organism that can be found in clean ponds of high nutrients, it is also capable of reproducing on its own.

• Green algae may be unicellular.• Most green aquatic and are found

commonly in freshwater.

Rhodophyta (red)• Rhodymenia is a flattened, fan shaped, and

rather stiff. The color is a light brownish-red as you can see on the fronds. These fronds can grow up to 100mm high. The fronds grow in all different shapes an sizes.

• Gracilaria is a red genus of red algae. Its economic importance is agarophyte, such as growing crops. It is also used as food in some parts of the world.

• Hypnea is a plant that grows up to 30cm long but usually most grow up to 15cm. It looks like a bushy tangled clump. They are commonly found in intertidal tide pools and on shallow reef flats.

• Lemanea is a fresh water species. Lemanea is a stiff bristle-like branched plant similar to a coarse horsehair. It grows up to 10cm long. When the plant is young it is a blue-green color.

Phaeophyta(brown)

• Sargassum is a genus of brown. It has numerous species depending on water temperature. It is referred to as plankton because its always drifting on the water. It can grow up to several meters long, and it has a robust but flexible body.

• Padina has a fan-shaped fronds. It attaches to rocks by rhizoids. Its found in lower rock pools and reef edges.

• Dicyota is a thallus flat and leaf-like plant that can grow up to 300mm long. The fronds are thin and translucent. The fronds are a yellow-brown color. These narrow spirally twisted plants can be found in mid-tidal pools.

• Fucus these plants consist of a flattened, dichotomously-branched thallus which has small stipe and a holdfast. The blade usually has a locally thickened area which is centrally placed and which is called a midrib. These are air bladders usualy present and they help keep the plant floating.
