Archivo: Seed Plant Female Gametophyte Variations

Descripción: Multiple examples of the variation of cell number in mature seed plant female gametophytes prior to fertilization. Each cell contains one nucellus unless depicted otherwise. A: Typical 7 celled, 8 nucleate female gametophyte (ex. Tilia americana). B: Typical gymnosperm female gametophyte with many haploid somatic cells illustrated with a honeycomb grid (ex. Ginkgo biloba). C: Abnormally large 10 celled, 16 nucleate angiosperm female gametophyte (ex. Peperomia dolabriformis). D: Abnormally small 4 celled, 4 nucleate angiosperm female gametophyte (ex. Amborella trichopoda). E: Unusual gymnosperm female gametophyte that is singled celled with many free nucelli surrounding a pictured central vacuole (ex. Gnetum gnemon). Blue: egg cell. Dark orange: synergid cell. Yellow: accessory cell. Green: Antipodal cell. Purple: Individual nucelli.
