Cone-bearing plants such as pine trees reproduce sexually through cones. Male cones produce pollen grains that are carried by the wind to female cones, where they fertilize ovules to produce seeds. The seeds are then dispersed by the wind or animals. Cone-bearing plants can also reproduce asexually through methods like grafting and layering, which create genetically identical copies of the parent plant.

4. Plant propagation is the process of increasing the
number of plants of a particular species or
There are two primary forms of plant propagation:
sexual and asexual. In nature, propagation of plants
most often involves sexual reproduction, or the
production of viable seeds.
What is plant propagation?

5. Plant propagation can be divided into
four basic types: sexual, asexual
(vegetative), layering, and grafting.
What are the different types of propagating plants?

6. Sexual propagation is the reproduction of
plants by seeds. The genetic material of
two parents is combined by pollination and
fertilization to create offspring that are
different from each parent. There are
several advantages of sexual propagation:
It may be quicker and more economical
than asexual propagation.
Sexual Propagation

7. Asexual propagation involves taking a
part of one parent plant and causing it
regenerate itself into a new plant. The
resulting new plant is genetically identical
its parent. Asexual propagation involves
the vegetative parts of a plant: stems,
roots, or leaves.
Asexual Propagation

8. Layering is a method of asexual
propagation in which a stem is made
produce roots while still attached to
parent plant. The parent plant provides
the new plant with water and nutrients
while the roots are forming. Layering can
be used for plants that are difficult to
propagate using other methods.
Layering Propagation

9. Grafting is a method of asexual plant
propagation that joins plant parts
different plants together so they will
and grow as one plant. This technique is
used to propagate plants that do not root
well from cuttings, to utilize superior root
systems, or to maintain clonal production.
Grafting Propagation

10. Grafting is a method of asexual plant
propagation that joins plant parts
different plants together so they will
and grow as one plant. This technique is
used to propagate plants that do not root
well from cuttings, to utilize superior root
systems, or to maintain clonal production.
Which method can we use to propagate cone-bearing
plants?

11. Cone-bearing plants have two types of
cones: female cones and male cones.
Reproduction begins when one of the
pollen grains from inside a pollen sac on
the male cone floats through the air to
the scale of a female cone. A pollen tube
then grows from the pollen grain toward
the female ovule.
