1. Kingdom Protista
MACRO-ALGAE

2. 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

4. 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

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

8. Blades
Stipe
Holdfast

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

14. 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

17. 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

18. 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.
