Rhodophyta (red algae) (How is this related to plants)
Once phylogenetically linked to cyanobacteria because they had two pigments in common.
two pigments rhodophyta has in common with cyanobacteria and their significance
Makes the algae red which allows them to live at great depths where only blue light penetrates.
Chlorophyta (green algae) (How is it related to plants)
They contain some of the same pigments: chlorophyll A&B and carotenoids. Also have chloroplasts.
Lynn Magulis (1967), serial endosymbiosis theroy - which states that over time energy producing prokaryotes were either ingestes as prey or were internal symbionts which continues to survive and eventually became a concrete symbiotic relationship. From green algae we get higher plants because theoretically, a larger protist engulfed the green algae cells which were eventually incorporated and became energy producing chloroplasts.
Chlorophyll A and B
method of energy storage
stores starch inside the chloroplast which makes it.
Composition of cell wall
cellulose and pectin
method of cell wall construction
plate formation at the end of mitosis
alternation of generations
specialized life cycle where the generations change ploidy with a diploid generation giving birth to a haploid generation and so on.
in algae: gametophyte and sporophyte are physically indestinguishable
in land plants: gametophyte and sporophyte are completely different looking.
1 - heteromorphic alternation of generations
2 - gametangia
3 - true tissues
4 - true organs
5 - waxy cuticle
6 - stomates
multicellular sex organs
made up of many specialized cells and together form a specific function
root, stem, leaf - which are made up of specialized tissues.
external to tissue, keeps the plant from dehydrating which still allowing gas out. on the underside of leaf, usually.
Breathing structures allowing gas exchange, usually on the bottom of the leaf.
