Week 6 Quiz-plant reproduction Flashcards
Pollinators
Get nectar (sugar,carbs) and pollen (protein) Pollinate the flier (accidentally)
Obligate outcrossers
Increases genetic variation
Saguaro
Reproductive success increases dramatically by keeping their flowers open a but at dawn
- temp is still low, so so is evaporation
- animals are active in the morning
Pollination methods
1-wind
2-animal
3-water
Ways to disperse seeds
1) wind
1) animal
3) water
Reasons why dispersal is important
1) parental competition
2) distant habitat -may be beneficial
3) “Planted” with fertilizer
4) population level- increasing of area of species means decreasing percentage of extinction
5) anti-predator protect against fungus
Wind dispersal
Seeds are small
Need something like wings or fuzz to catch the wind
Animal dispersal
- Accidental-bars and burrs
- active: put energy in it; carbs, protein, lipids: fleshy coating around sees
Flower uses
Showy
Attract pollinators for the pollinators’ food
