By Alexis, Katie and Adel Angiosperm By Alexis, Katie and Adel

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

Structure

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

Function Sepal: Protects flower bud before it opens

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

Function Stamen: Male reproductive parts of a flower

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

Function Filament: Stalk that holds the anther

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.

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

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

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
