This document discusses the structures and functions of different plant parts. It describes that roots absorb water and minerals and anchor the plant, stems support the plant and transport nutrients, leaves produce food through photosynthesis, and flowers contain male and female parts to produce seeds and attract pollinators. The female part of a flower is called the pistil, which has four parts - stigma, style, ovary, and ovule. The male part is called the stamen.

1. The Structure of
Plants and their
Functions

2. Plant

3. Roots
•Like a straw; absorb
water and minerals
•Anchors plant
•Stores food for future
use

4. Stem
•Supports the plant
•Plumbing system
•Gets nutrients to the
plant

5. Leaves
•Make the plants food
•Makes food by
capturing sunlight
(photosynthesis)

6. Flower
• Makes the seeds
• Female Part: Pistil
• Male Part: Stamens
• Petals attract pollinators

7. Quiz
What is the function of the
stem?
A) Make Food
B) Support plant/ Act like
plumbing system
C) Absorb water/nutrients

8. Flower

9. Pistil
•Stigma
•Style
•Ovary
•Ovule

10. Stigma
• Sticky bulb
• Center of flower
• It’s job is to hold the pollen

11. Style & Ovule
• Style is the long stalk
that holds up the stigma
• Ovule becomes the seed

12. Ovary & Sepal
• Located at the bottom of
the flower
• Contains the ovule
• Sepal: protects the flower
while it’s developing from
a bud.

13. Stamens
•The male part of the
flower
•Anther
•Filament

14. Anther and Filament
• Anther produces and
contains pollen
• Filament: hair-like stalk
• Anther sits on top of
Filament

15. Quiz
1)What are the four parts that make
up the pistil?
• Stigma
• Style
• Ovary
• Ovule
2) Is the pistil male or female?
• Female

16. Fun Fact
• The receptacle is the
attachment of the flower to
the stalk: in some cases it
becomes part of the fruit
after fertilization.
