Angiosperm

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 suns 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 Examples
