A
Roots
B
Stem
C

Slide 8 - Quizvraag

Slide 9 - Open vraag
How does a plant grow from a seed?
Flowers become fruits!
Seed coat
=
outer layer that protects the germ and cotyledons.
Cotyledons
(
ko·tuh·
lee
·dnz
) = the first pair of leaves with reserve food for the germ.
Germ
= the very young plant that is inside a seed.
Slide 10 - Tekstslide
Germinating
First, the seed coat absorbs water.
This causes the cotyledons to swell and the seed coat to burst open.
Then the roots start growing.
Then the stem and the leaves grow.
Why do the roots start growing before the leaves?
Slide 11 - Tekstslide
Growth
Cell division
and
cell growth
Meristems
= the far ends of stems and roots; here, the plant forms new cells
Development
Slide 12 - Tekstslide
Branch
terminal bud =
a bud at the end of a branch, from which tree branches get longer
lateral buds =
buds on branches from which new side branches grow
bud scales
= scales that protect the bud on a branch against the cold and insects
bud scale scar =
a ring-shaped scar on a branch, at the spot where the bud scales fell off a terminal bud (one year).
Slide 13 - Tekstslide
Stem
Growth layer
= New wood cells are formed there in spring and summer.
Annual growth ring
= layer of wood cells that is formed in one year, (oldest in the middle)
Light brown
= Wood cells that develop during spring (large and thin cell walls).
Dark brown
= Wood cells that develop during summer (smaller and thicker cell walls).
Information about the tree (age, drought, pest, growing at an angle)
Slide 14 - Tekstslide
Why does a root grow downwards?
gravity
starch granules sink down
stem responds to sunlight
