Explanations: answer key for all 10 questions
- Q1: What is the male part of a flower called?
Answer: Stamen
It has an anther and a filament.
- Q2: Where is pollen produced?
Answer: In the anther
It sits at the top of the stamen.
- Q3: What is the female part of a flower called?
Answer: Pistil or carpel
It includes the stigma, style and ovary.
- Q4: What does the stigma do?
Answer: Catches pollen
It is often sticky.
- Q5: What are sepals?
Answer: Leaf-like parts that protect the bud
They are usually green.
- Q6: What does the ovary become after fertilization?
Answer: The fruit
The ovules become seeds.
- Q7: What is the main job of colorful petals?
Answer: Attracting pollinators
Scent helps too.
- Q8: Which scientist classified plants by their flower parts?
Answer: Carl Linnaeus
His system counted stamens and pistils.
- Q9: What is a perfect flower?
Answer: One with both male and female parts
Lilies and roses are perfect flowers.
- Q10: Where is nectar usually made?
Answer: In nectaries at the base of the flower
It rewards visiting insects.
Flower Anatomy Quiz – Inside a Bloom
A flower is the reproductive part of a flowering plant. Most flowers have four main rings of parts: green sepals that protect the bud, colorful petals that attract pollinators, male stamens that make pollen and a female pistil that holds the ovules.
When pollen lands on the sticky stigma, it grows a tube down the style to reach the ovary. There, fertilization turns ovules into seeds and the ovary swells into a fruit. Nectaries at the base of many flowers produce sweet nectar to reward bees, birds and other visitors.
Flower shapes vary hugely, from the open cups of buttercups to the complex lips of orchids. Carl Linnaeus used the number of stamens and pistils to classify plants in the 1700s, and botanists still study flower anatomy to understand how plants evolved and reproduce.
