NOT A BOUQUET lol
What is a flower?
They are angiosperms and are plant structures that allow sexual reproduction to take place.
What are flowers composed of?
Modified leaf parts
What happens after pollination and fertilization?
Part of the flower enlarges and becomes the fruit
What is the fruit otherwise known as?
The ovary
What is inside the ovary?
The ovules aka seeds.
The ovules inside the ovaries become seeds
What is a peduncle?
Stem that bears a solitary flower, or an inflorescence (aka the main flowering stem)
What is a pedicel?
The stalk that bears a single flower within an inflorescence (attaches flower to peduncle)
What is a bract?
Leafy structure that extends underneath a flower that is a modified leaf
What is a receptacle?
Enlarged tip of the flowering stalk upon which the floral parts are attached (directly on top of peduncle or pedicel)
What is a sepal?
The outermost series of flower parts, surrounding the petals, enclosed and protects the flower bud, leaflike, and usually green
What are tepals?
The name given to both sepals and petals when they are attractive and look alike
What are some examples of plants with tepals given in class?
Tulips or daylilies
What is a calyx?
All the sepals together (aka a collection of sepals)
What is a petal?
Set of floral parts inside of the sepals, often brightly coloured
What is a corolla?
Greek word for crown; All the petals of a flower
NOT A TOYOTA COROLLA RIP
What is a perianth?

Produces pollen grains
What is a filament and what does it do?
Slender stalk that bears the anther at its tip
What is an androecium?
Name for all the stamens together in a flower (aka collection of stamen)
What is the pistil?
Central female reproductive structure consisting of stigma, style and ovary (there can be more than one pistil in a flower)
What is the stigma?
Sticky surface where pollen grains land
What is the style?
Tube that connects stigma to the ovary
What are undeveloped ovules?
Found inside ovary; after pollination and fertilization, the ovules develop into seeds
What is the carpel?
Chamber subdivision of pistil; may contain one carpel or two or more fused carpels
What is an example of a fruit with carpels?
Apples, oranges, tomatoes
What is a gynoecium?
