The document summarizes the key characteristics of the ginkgo tree. It notes that ginkgo can grow up to 40 meters tall, prefers temperate and polluted regions, and requires annual precipitation of 1767 mm. The stem is straight and wide, with grayish bark that is deeply fissured. Male ginkgo trees produce pollen sacs in clusters, while female trees bear pairs of green ovules on stalks, usually with only one developing into a seed. The document distinguishes male and female shoots, describing differences in their leaves, petioles, and reproductive structures.

10. • Ginkgo is a tree that
grows up to 40 m
height
• Prefers places that
were polluted,
temperate regions.
• Annual precipitation
of 1767 mm

11. A.Stem
- Straight (40 m )
- Girth (13 ft ot 4m
wide)
- Bark is deeply
fissured, grayish
to grayish brown
color
- Woody, branched
- Slow growing

12. • Male ginkgo
trees produce
pollen in
clusters of
pollen sacs that
resemble
catkins 3 - 6 cm
(about 1 1/4" - 2
1/4") long.

15. • Pairs of green
ovules are borne
on female trees
on stalks 4 - 5 cm
(1 1/2" - 2") long.
Usually only one
ovule develops
into a seed.

17. • Female Shoot
= the petiole is long and
thin
= Two ovules (one will be
used)
= the leaf is broaden
= petiole is long and thin
• Male Shoot
= the petiole is short and
thicker
= has strobilus
= leaf is enfolded at the
base
= shorter and thicker
than female
