An ______________ characteristic is passed down from parents to offspring.
Inherited.
200
Pollination is....
the movement of pollen from a stamen to a pistil or from a male cone to a female cone.
200
Which part of the flower holds the ovules?
The ovary holds the ovules.
200
What is the function of the seed coat?
It protects the embryo and keeps it from drying out.
200
What are the four main stages in the life cycle of a flowering plant?
Germination, growth of the seedling, maturity and seed formation.
200
What are some inherited characteristics among tulips?
Shapes and colors of the petals and leaves, the position of the flower at the end of the stem.
300
In Fertilization,......
An egg and a sperm cell join.
300
What parts of the flower help a flower make seeds and fruits? (there are 3 parts)
These parts include petals, stamens, and pistils.
300
Why is it important for a seed to have stored food?
It is the food supply that helps the embryo grow.
300
What are the two kinds of plants that make seeds?
Conifers and Flowering Plants.

How does it help flowers to have bright, colorful petals?
The petals attract insects of other animals.
400
Why is seed dispersal so important to a plant? What would happen if its seeds were not dispersed?

Taylor is studying the reproduction of a pear tree. She cuts a pear from the tree to observe its seeds. What method of seed dispersal is most likely used by the pear tree?
Animals eating the plants fruits and dropping the seeds in a new place.

500
A Life Cycle is....
All the stages a living thing goes through as it grows and reproduces.
500
How is pollination related to pollen?
Pollination is the transfer of pollen between flower parts.
500
When a seed germinates, where does the new plant get the energy it needs to grow?
From food stored in the seed.
