Slide 3
v c n m Most plants reproduce by making seeds and dropping them
on the ground.
Slide 4
v c n m But new plants need sunlight and room to grow.
Slide 5
v c n m If the seeds stay near the parent plant, the new plants
might be in the shade and not have enough light to grow very
well.
Slide 6
v c The new plants may be too crowded to grow properly.
Slide 7
v c Parent plants need a way to disperse their seeds some
distance away so the new plants can thrive.
Slide 8
v c Disperse is a word that means to scatter or send things
away in different directions. It is the opposite of gather.
Slide 9
v c But plants cant walk around to put seeds in different
places. How can a plant disperse its seeds?
Slide 10
v c Plants have adapted several ways to disperse their
seeds.
Slide 11
v c Some seeds are also nuts that animals like to eat. Some
animals hide nuts for later by burying them in the ground.
Slide 12
v c If the squirrel forgets where he buried the acorn, he has
planted an oak tree that may produce thousands of acorns.
Slide 13
v c Some plants surround their seeds with tasty fruits.
Slide 14
v c Animals eat the fruit then walk away and drop the seeds
when they poop. Many seeds can still grow after passing through an
animals digestive track.
Slide 15
v c Birds may carry seeds far away from the parent plant.
Slide 16
v c Some plants put their seeds in sticker burrs that can grab
onto passing animals.
Slide 17
v c The animals might walk a long way before the burrs fall
off.
Slide 18
v c Some plants make seeds that can travel on the wind.
Dandelion seeds act like little parachutes that only take off when
the wind blows them.
Slide 19
v c Cocoanut seeds can float in the ocean for weeks. The
cocoanut may wash up on a beach thousands of miles from the parent
tree and grow into a new tree.
Slide 20
v c Plants have adapted several ways to disperse their
seeds.
