Plants

what are plants known for

being the primary producers forming the base of the food web

how does plant diversity help humans

• enhances climate regulation thru carbon sequestration

• increases soil fertlity thru nutrient cycling

• habitat creation for diverse animal species

why is photosynthesis essential for life

• releases o2 used in cellular respiration and stores energy in sugars

how has endosymbiosis contributed to the evolution of plants

• allowed photosynthetic bacteria to become chloroplast w/ plant cells

what is red alage made from

• muliticellular marine group w/ phycoblin pigments and no flagella

what makes up brown alage

• marine macroalage w/ fucoxanthini from red algae via secondary endosymbiosis

green algae is composed of

• diverse groups including chlorphytes using charophytes using chlropyll a and b

how can we restore areas being a carbon sink

• strengthen native land right/practices

• implementing reforestation efforts using native species

what is some evidence that suggest land plants evolved from algae

• both have cellulose cell wall as well as chlorophyll a+b

how can adaptions of algae improve practices like seaweed farming + aquaponics

• its multicellular + nutrient absorption thru cells surface help support nutrient cyling thru aquatic farming systems

ecological functions of algae

• support food webs by converting inorganic C into biomass

• stucturing marine ecosystems by acting as habitat- forming species

support food webs by converting inorganic C into biomass is also reffered to as

• photosynthesis

how does plant biodiversity influence the ecosystem

• stablizing and demonstrating the resillence enabling enviorments to better withstand and recover from changes

what is ethanobotany

• study of how people of a particular culture or region make use of native plants

what is ethnobotany role in biodiversity

• reclaiming knowledge from people who live on or take care of the land is a method of healing + improving biodiversity

3 sisters

• grow plants that work together + occupy dif niches

• ex: corn, beans, and squash

traits that are shared by all plants

• cell wall made of cellulose

• has chlorplast

• alternation of generation

what are some roles plants play in supporting life on earth

• flitering pollunauts from water + soil

• moderate climate by storing C

• producing O2 via photosythesis

how does ehtnobotanny support biodiveristy

• combines science and knowledge to guide sustainable practices

what did Dr Lynn Margulilus do

• proposed theory of endosymbiosis

endosymbiosis refers to

• one cell engulfing another no digestion, its cell chem became align and symbiotic

why is endosymbiosis revolutionary

• since insetad of reconzgining another organisms as forigen they forged a symbitotic relationship both benefit

ex of ensymbiotic relationship

• bees and flowers

which group of alage is most closely releated to land plants

• charophytes(green alage)

how to tell the difference between primary and secondary ensymbiosis

• secondary will have multiple membranes

primary vs secondary ensymbiosis

• primary is engulfing of 1 cell

• secondary it can be engulfing of multiple

what led to the origin of chlorplast

• primary endosymbiosis of cyanobacteria

why do we study alage for plant evolvution+ making stress tolerant crops

• alage lived in freshwater, they must have adapted and devleloped system to surivive in these conditions

• may give us starting materials
