Practical 4 Flashcards
Anther
The pollen-bearing part of the stamen - supported by the filament.
Calyx
All of the sepals of a flower.
Corolla
Inner whorl of petals of a flower.
Filament
Narrow part of the stamen which supports the pollen-bearing anther.
Ovary
Female reproductive organ containing ovules.
Petal
Modified leaves that surround the reproductive parts (often brightly coloured).
Pistil
Female part of the flower, consisting of stigma, style and ovary.
Receptacle
The part of a flower stalk where the parts of the flower are attached.
Sepal
The outer parts of the flower (often green & leaf-like) - covers the outside of flower bud.
Stamen
The male part of a flower producing pollen, consisting of anther and filament.
Stigma
The enlarged sticky area (on the end of the style) which receives pollen.
Style
The slender part of the pistil which connects the stigma with the ovary.
Eudicot vs Monocot flowers.
Eudicots typically have sepals and petals in fours, fives, or multiples of them.
Monocots typically have flower parts in threes
or multiples of three.
What is the function of the calyx?
Protect the flower during development.
What is the function of petals?
Surround the reproductive parts of flowers and attract pollinators with their bright colours or unusual shapes.
1st whorl
2nd whorl
3rd whorl
4th whorl
1st whorl = Calyx
2nd whorl = Corolla
3rd whorl = Stamens
4th whorl = Pistil
How do dispersal of seeds occur?
A. Seed dispersal by animals e.g. cassowary, possum, dog
B. Seed dispersal by wind e.g. pepper-pot, parachute, wings
C. Seed dispersal by hydraulic expulsion e.g. squirting cucumbers
D. Seed dispersal by water e.g. coconut
E. Seed dispersal by parent e.g. peanut
