Definition
special stems that grow along the ground and that grow roots and leaves along the way causing the plant to spread
Term
bulbs
Definition
a types of underground stem that is made of thick, fleshy leaves that store food and grow into new plants
Term
how scientists classify living things
Definition
by asking:
how many cells does it have?
where does it live?
how does it get food?
Term
how animals adapt to survive
Definition
examples include:
ptarmagins blend in for protection
some frogs have developed poison to protect themselves
some animals migrate to find food
bears hibernate through winter when food is scarce
Term
how plants reproduce
Definition
three ways:
seeds
spores
bulbs
Term
parts of a flower
Definition
petals--colorful, attract pollinators
sepals--special leaves, protect bud
pistil--female part
ovary--female part, bottom of pistil,
stores eggs
stamens--male part
anthers--male part, top of stamens,
make pollen
Term
how pollen moves from stamens to pistil
Definition
two ways:
animals getting nectar
wind blowing it
Term
why seed dispersal is key to plant survival
Definition
seeds need to be spread so they can end up in places far away from the parent plant where they have room and the right conditions to grow; if all the same plants are too close together, they can be wiped out by fire, flood, clearing of the land
