|This page will cover the Marine Plants. Unlike the usual plants you see every
day Marine Algae have no root system, stems, leaves or flowers. Instead they have three
main parts; the blade (leaf), the stipe (stem) and holdfast (roots). The plant phylums are
classified acording to pigmentation, general structure, food-storage products, and
Blue Green Algea will be a common site an tidepools. It is the blackish color found on rocks at the high tide line. Lacking Chloroplasts and Nuclei these are very simple and primitive organisms, simalar in structure to bacteria. However it is very old. This algae was around two billon years ago. To prevent drying out at low tide, Blue Green Algae forms an outer wet layer, it is extremely slippery, so be very carefull.
Red Algae Red Algae is the most advanced group of plants. They're so advanced they can be found both in tidepools and at debths of over 600ft due to their abilitty to absorb longer wavelengths of light. You might not know it, but you may use red algea every day. For instance the carrageenin of Irish Moss can be found in ice cream, toothpastes, lipstick, jells... This widely used plant can be found in lower and subtidal zones. This short, but terf-like algae dominates space in lower zones. Irish Moss has flat, branched blades and a small holdfast. Underwater its tips look iridescent blue. Now, how about seeing Map of Irish Moss ocurences in my area of Durham, New Hampshire.
