three components of a seed
plant embryo, protective covering, food supply
What does a thin tree ring indicate?
year of drought
advantage of seed dispersal far from the parent plant
less competition
early growth stage of plant embryo
germination
responses of plants to external stimuli
tropisms
What are the characteristics of the kingdom fungi?
eukaryotic, heterotrophic, absorb their food, cell walls of chitin
What is the function of a food vacuole?
stores food
How are fungi like plants?
cell walls
Why would a plant close its stomata?
to prevent water loss

decomposition
How are cilia and flagella alike?
used for locomotion
How are cilia and flagella different?
cilia are shorter than flagella
What organism causes ringworm?
fungus
Which structures regulate gas exchange by opening and closing the stomata?
guard cells
waxy coating on leaves
cuticle
purpose of the cuticle
prevent water loss
How are cacti adapted to desert conditions?
needles reduce water loss, thickened stem stores water, shallow roots soak up water quickly
Lightweight seeds with “wings” are likely dispersed by _____.
wind
Where does reproduction take place in angiosperms?
flowers (ovaries)
Where does reproduction take place in gymnosperms?
cones
movement of a plant in response to gravity
gravitropism
movement of a plant in response to touch
thigmotropism
plant that lives many years
perennial
