Week 6 Quiz-plant reproduction Flashcards
(9 cards)
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
