Reproduction
What is the main purpose of flowers in plants?
To attract pollinators with colorful flowers and sweet smells
What type of plants reproduce using cones?
Conifers
What are the methods by which seeds can be spread?
wind, water, animals, humans
Some seeds float on water away from parent plants because they are
have a hollow like structure
What do we call the structure in a flower that contains the ovary?
Pistil
What part of the flower develops into fruit?
Ovary
What type of cone contains pollen?
male cones
How do animals help in seed dispersal?
it can attach to their furry, they can carry it and drop it, or they excrete the seeds.
What do seeds and spores have in common?
They both eventually grow into new plants
What is the term for the male part of a flower that produces pollen?
Stamen
What is the fruit's job?
to protect the seed
What is the most common way pollen is transferred in cones?
Wind
Why do seeds scatter?
They can grow, thrive, have access to more water and nutrients away from parent plant(s)
Why is it important for seeds to be able to scatter?
It is important for seeds to scatter so they can grow into a new plant in a new location with possibly more water and nutrients.
What do you call the product of reproduction?
offspring
How is pollen transported to the pistil?
Wind, water, animals
Explain the differences between male and female cones
Males cones- smaller, soft have pollen
Female cones- larger, hard
What is a reproductive structure that is similar to a seed but smaller?
Spore
Describe one structure that allows seeds to travel through the air.
structures that look like wings, parachute types structures
Explain the first step in plant reproduction, fertilization-
Pollen from the stamen has to reach the pistil

True or false?
What is the difference between cones and flowering plants?
Cones are either male or female. They do not have pistils and stamens. They don't have flowers.
How are moss spores and fern spores different?
