Hapliod

Exine is on the outside and covering the the object

The objects will undergo germination to form mature microgametophyte

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

The large open cells are an example of parenchyma cells

The butterfly shaped objects are called Anthers

Will contain an ovule at maturity

"small objects" are spores

Spores are haploid

Sporangium is what surrounds the small objects

The smaller circular cells are microsporocytes

Microsporophyll is the tissue surrounding the column of cells

Screenshot 2024-05-10 at 2.58.41 PM

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 outer ring of cells is dermal tissue

The eyes looking orbs are likely vessel elements

Screenshot 2024-05-10 at 3.13.57 PM

This region is said to be early wood

The large open cells are most likely vessel elements

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
