Selective breeding
What is Sexual reproduction
involves the production of seeds and fruits from specialized cells of two plants.
The _____ is the part of the tree that has a series of woody scales.
cone
Most flowers have male and female parts that are needed for reproduction. The male part is called the
stamen
This means the sperm fertilizes the eggs in the same plant.

canola
What is vegetative reproduction?
occurs when a “parent” plant grows new plants from its roots, stems, or leaves.
Female cones contain ovules or _____
eggs
the female part of the flower is known as the______
pistil
the eggs of one plant are fertilized by sperm from another plant of the same species.
cross-pollination
Canola was developed using selective breeding and originated from a plant called

This tree reproduces vegetatively by producing new plants from their roots.
Trembling aspens
The process of pollen travelling to the female cone is called
pollination.
usually the brightly coloured parts of the f lower. They are the flower’s banner to advertise its tasty nectar or pollen.
Petals
This occurs when a pollen grain lands on the stigma.
pollination
Plant scientists now have the ability to make changes to plants by going inside an individual plant cell and changing some of its material. They do this by first removing the parts of the cell that control its characteristics. This material is called the genetic material or _______ of the plant.
genes
This is a form of vegetation reproduction in which plants reproduce from their stem. .
layering,
When do the female cones of pine trees mature, open, and release their seeds ?
during the fall or winter months
usually green and are underneath the flower. They protect the flower before it opens.
Sepals
This is actually the giant female flower of the corn plant.
Corn on the cob
Plants can reproduce in two quite different ways. Can you name them?
Sexual reproduction and Asexual, or vegetative reproduction,
This means to take a branch from one tree and attach it to another tree.
Grafting
Flowers that aren’t brightly coloured often depend on ____ to spread their pollen.
wind
The pistil has three main parts. Can you name them?
