Parts of Flowers & Seeds
This sits at the top of the stamen, produces pollen
This occurs when a grain of pollen lands on the stigma of a flower
Pollination
What begins to grow after fertilization?
Zygote
These cones grow at the tips of the branches
Male cones
How many cells does a spore consist of?
One
This is the female reproductive system of the flower, consists of the ovary, style, and stigma
Pistil
Name two ways pollination occurs
Wind
Insects, birds, other animals
What is the tiny new plant called?
Embryo
When wind blows pollen into a female cone, what happens to the scales of the cone?
They close
Spores of ferns are carried away by one of these two sources.
Wind
Water
This is the part of the flower that traps pollen grains that fall from the anther or are carried to the flower
Stigma
This is when pollen is transferred from the anther of a different flower
Cross-pollination
This part of the plant grows to become the fruit of the plant
Ovary
Conifers are usually one of these 2 things.
Evergreen trees
Shrubs
Plants that produce spores need more of this than seed-bearing plants
Water
These three things are required for seeds to germinate
Water
Oxygen
Proper temperature
This occurs when a male sperm cell inside the pollen unites with the female egg cell in the ovary
Fertilization
Fruits can be classified into 2 categories - name them.
Dry or Fleshy
What does the ovule develop in to after fertilization?
A seed
What is a spore missing that other seeds have?
Name the three parts of a seed
Embryo
Cotyledons
Seed coat
What type of reproduction involves both a male and a female cell?
Sexual reproduction
Without cutting open the flower, how can you tell how many ovules were in the pistil?
The number of seeds in the fruit
Why is wind the best dispersal method for the seeds from a cone?
They need to be farther from their parent tree to have adequate resources for growth
What produces the spores of a fungi?
Fruiting body
