What were some disadvantages for moving up to land?
Maintaining Moisture
Supporting their body
Obtaining resources
Adaptation: How do plants maintain moisture?
land plants have a waxy cuticle and cells that open and close the stomata
bring carbon in and letting waste and water out
Adaptation: How do plants support their body?
lignin helps plants support their body against the pull of gravity
Adaptation: How do plants obtain resources
on land, plants obtain water and minerals from roots in the soil
CO2 from the air and sunlight through leaves in the air
Sporophyte is the only ____ lifestage

filament
holds up anther
anther

Sporophyte
What are Similarities between plants and Charophytes
share same ancestor

photoautotrophic
What is a difference between plants and charophytes
plant cell walls contain cellulose (not in algae)
Monocots (one cotyledon)
single leaf

How do monocot and eudicot embryos differ?
Monocot has one cotyledon
eudicot embryos have two cotyledons
How do monocot and eudicot leaves differ?
Monocot leaf veins are parallel
Eudicot leaf veins are netlike
How do monocot and eudicot stems differ?
Monocot tissue is scattered
Eudicot tissue is arranged in a ring
How do monocot and eudicot roots differ?
Monocot roots are fibrous (no main root)
Eudicots have taproot (main root usually present)
How do monocot and eudicot pollen differ?
Monocot pollen grains have one opening
Eudicot pollen grains have three openings
How do monocot and eudicot flowers differ?
Monocot flower organs come in multiples of 3
Eudicot floral organs come in multiples of 4/5
What is the closest living land relative to plants?
Green Algae/Charophytes?
Mitosis
cells make exact copies of themselves
Meiosis
ploidy will divide in half
Hepatophyta (liverwort)
Anthocerotophyta (hornwort)
Bryophyta (moss)
Lycophyta
Sphenophyta (horsetail)
Pterophyta ( fern )
Species richness
The number of species in a biological community.
relative abundance
The proportional abundance of different species in a community.
3 components of biodiversity
genetic, species, and ecosystem diversity
3 components of biodiversity
genetic, species, and ecosystem diversity
herbivory
+: herbivore eats part of plant
-: Plant gets harm but doesn’t die/takes energy to regrow
Mutualism
++: both species benefit
Commensalism
+/0: one benefits the other is not harmed; wildflowers, trees
Parasitism
+/-: one benefits the other is harmed or killed; tapeworms
predation
+/-: one organism is killed (prey) the other eats the organism (predator)
