Pistil:
Female structure (stigma, style, ovary, ovules
Stigma:
Sticky surface that attracts pollen grains
Style:

Ovary:
Hollow, bulb-shaped structure in style which hold ovules
Ovules:
Small, round cases inside ovary which contain egg cells and turn into seeds when egg is fertilized
Stamen:
Male Structure (Anther on top of filament)
Tube Nucleus:
portion of pollen grain cells that pave the Pollen Tube
Sperm Nuclei:
The two sperm nuclei that follow the Tube Nucleus. One fertilizes and the other forms endosperm which feed embryo
Endosperm:
Food supply for a newly fertilized seed formed by two nuclei polar nuclei
Pollen Tube:
burrow produced by the TUBE NUCLEUS so that sperm nuclei can reach the ovule
Shoot Apex:
The tip of the stem in plants which is composed of meristem tissue which is capable of quick growth
Terminal Bud:
The beginning of a new set of leaves
Fruit:
Matured Ovary which contains seeds (provides protection and as well as method to disperse them)
