Sepals*
Modified leaves that make up the outermost ring of flower parts and protect the bud
Often green like other leaves
Cover and protect the flower while it is a bud
As the blossom opens, the sepals fold back.

Petals*
Broad, flat, thin leaflike parts of a flower
Vary greatly in color and shape
Attract insects or other animals to the flower
These animals/insects help plants reproduce by carrying pollen from flower to flower

Stamen
Consists of two flower structures
Each stamen has a thin stalk called a filament.
The filament is topped by an anther.
Anthers are saclike structures that produce pollen.
A stamen is a male reproductive structure of flowers

Pistil Consists of three flower
structures Found in the center of most
flowers Tip of the pistil is called the
stigma Pollen grains collect on stigmas,
which are often sticky or feathery
Long, slender part of the pistil in the style
Rounded base of a pistil that contains one or more ovules in call the ovary
Female reproduce structure of flowers

Ovule*
Each ovule contains an egg
When the egg is fertilized, the ovule develops into a seed
The ovary develops into a fruit

Virtual Investigations: Plant Processes
As a class, we will complete Lab 2 of the Plant Processes Virtual Investigations
We will determine the stages of plant development
