Mature microgametophyte
Nucleus towards the tip is the TUBE nucleus
The clearish objects to either side are the air bladders
The nucleus left behind is the SPERM nucleus
Hapliod
Exine is on the outside and covering the the object
The objects will undergo germination to form mature microgametophyte
"small objects" are spores
Spores are haploid
Sporangium is what surrounds the small objects
Microgametophytes are haploid
The column like cells make up the tapetum
The smaller circular objects are Microgametophytes
Lollipop structure is an Antheridium
Sperm is the pinkish structures inside that are mature
The ploidy level of everything is haploid
The vase-like structure is an archegonium
The circular object inside is an egg
The ploidy level of everything is haploid
The dark red circle is the endodermis
The layer of cells just inside the circle is the pericycle
These cells are filled with organelles called amyloplasts
The butterfly shaped objects are called Anthers
Will contain an ovule at maturity
The smaller circular cells are microsporocytes
Microsporophyll is the tissue surrounding the column of cells
The outer ring of cells is dermal tissue
The eyes looking orbs are likely vessel elements
This region is said to be early wood
The large open cells are most likely vessel elements
The large open cells are an example of parenchyma cells
