Kingdom Protista MACRO-ALGAE

Kingdom Protista Kingdom Plantae The debate.... Are they Protista or are they Plantae? Kingdom Protista Kingdom Plantae Contains chlorophyll A contains chloroplasts some can grow very large some scientists say most algae is in Protista other than green, red, brown both unicellular and multi-cellular doesn't have true roots a bit of a transition towards plants

contains chlorophyll (type of photosynthetic pigment) Phylum Chlorophyta GREEN ALGAE contains chlorophyll (type of photosynthetic pigment) usually in intertidal zone as the sunlight that chlorophyll a and b uses doesn't penetrate the ocean well

Phylum Phaeophyta BROWN ALGAE most common type of algae carotenoid pigment fucoxanthin

Blades Stipe Holdfast

Phylum Rhodophyta RED ALGAE phycoerythrin photosynthetic pigment red algae has a pigment that can penetrate deep into the ocean (absorbs blue light)

Each photosynthetic pigment will absorb different wavelengths of light Different wave lengths of light penetrate the ocean surface to different depths That is why you will find different algae at different parts of the intertidal zone

Algae Uses food for people and livestock high iodine therefore improves thyroid function and decreases goiter issues shampoo (thickener) ice cream thickener phamaceuticals paint agar pie fillings canned meat

Photosynthesis in Algae most important living things on our green planet are single cell algae they are the most important because they produce oxygen, more oxygen than anything else does Human beings and most animals have to have oxygen to breathe and live oxygen is produced through a process called photosynthesis, where algae and plants use sunlight, water and carbon dioxide to produce the oxygen.
