By Alexis, Katie and Adel

2. It is a plant that has flowers and produces seeds within a carpel
What is an angiosperm?

3. Structure

4. Function
Receptacle:
Thickened part of the stem where the flower organs are attached

5. Function
Sepal:
Protects flower bud before it opens

6. Function
Petals:
Usually most colourful parts of flower that attract pollinators

7. Function
Stamen:
Male reproductive parts of a flower

8. Function
Anther:
Made up of lobes that attach to the filament. The lobes hold sacs containing pollen.

9. Function
Filament:
Stalk that holds the anther

10. Function
Ovary: Protects ovule after fertilization and becomes the fruit
Ovule (inside the ovary): Structure developing in the ovary and contains the gamete which develops into the seed.

11. Function
Style:
Long tube which attaches stigma to the ovary. Pollen will slide down to fertilize the egg.

12. Function
Stigma:
Top of the carpal that is sticky to catch the pollen

13. Review Vascular tissue
xylem: transports water and nutrients from the roots to the leaves
- phloem: transports sugars everywhere throughout the plant
Cuticle: Waxy layer on top of the leaves that helps leaves to retain water
Roots: absorb water and nutrients
Leaves: Converts the sun’s energy into food for the plant
Stem: Supports the leaves, flowers, fruits connecting them to the root and conducts water, nutrients, and products of photosynthesis to and from roots and leaves
