Science: Plants and Ecology Flashcards
_ plant
Leaves produce food
Roots absorb water through soil
Tissues transport water and nutrients through stem
Vascular plants
Special tissue plants use transports water and minerals
Transport sugars through plants
Xylem
Phloem
Male reproductive organ on flower
Female reproductive organ on a flower
Stamen
Pistil
Pollen stored in
Anther
Ovary of the flower
Carpel
Receives the pollen ( male reproductive cell)
Stigma
Part of seed that provides nourishment for the plant embryo
Endosperm
Plant with only one embryo in each seed
2 examples
Monocot
Corn
Wheat
Plants with two embryos on each seed
Ex:
Dicot
Beans
Nonflowering plants that use seeds to reproduce, carried by wind
Ex:
Gymnosperms (naked seeds)
Confiers - pine , cedar , redwood
Single celled reproductive body
Ex: ferns and mosses
Spores
Attractive nature encourages animals to pollinate the plant
Angiosperms
5 levels of ecology(small to large)
Old People Catch Easy Break
Organisms Populations Communities Ecosystems Biosphere
Organisms place in the food web called
Trophic
Development and changes that occur during colonization of a new habitat such as newly exposed rock
Primary succession
Changes to previously colonized habitat tat has been disrupted but events like forest fires
Secondary succession
Collection of plant and animal communities that exist within specific climates * living features only (biotic)
* can exist across continents
Biomes
Tropical rainforests
_ biome
Defined by distinct patterns in temp and rainfall
Terrestrial biomes
_ biome
Defined by type of water and organisms
Aquatic biome
_ trees lose leaves in winter
_ keep leaves year round
Deciduous
Evergreen
Primary consumer
Secondary consumer
Tertiary consumer
Herbivores
Carnivores consume herbivores
Carnivores consume carnivores
Aquatic biome - river meets ocean
Shrubland biome
Tropical grassland, nutrient poor soil
Estuary
Chaparral
Savanna
