Lab Practical, All known as plastids (parenchyma cells) # # #, Male and…

- - - - mouth is airspace
      - border outside is schlerid tissue (fibers)
      - eyes and nose are xylem also red
      - forehead and jaw area is phloem
      - small cells in forehead are companion cells
      - larger cells in forehead are sieve tube member cells
- - - - Megagametophyte
        
        female structure is archegoniophore
        
        archegonia contain eggs and are the structures hanging from the underside of the umbrella
        
        Egg is contained inside archegonia (only one egg)
        
        thallus is base
        
        everything is haploid
      - Microgameophytes
        
        Male structure
        
        base is thallus
        
        also known as antheridiophore
        
        antheridium is the barrier or structure around the sperm
        
        sperm is in the red area at the top of the antheridiophore
      - the leaf structure we see for the plant
    - - attached to archegoniophore (haploid)
      - archegonia tissue (the blue) is called calyptra (haploid)
      - sporophyte is the entire hanging structure (seta & sporangium) diploid
      - Seta is base
      - sporangium covering spores
      - spores are the purple dots inside sporangium (haploid)
  - - - antheridium contain the sperm
      - sperm is the purple spores inside
      - paraphysis structures between antheridia
      - Male structure
      - Stalk connects antheridium to the base
      - everything is haploid
    - - female structure
      - archegonia are long structure that contains the egg
      - paraphysis is thin structures between archegonium
      - venter is swollen part of archegonia
      - Neck allows passage for sperm at opening of archegonia
      - stalk attaches archegonia to rest of gametophyte
    - - Capsule is whole structure or body (diploid)
      - tip/cap is known as operculum (diploid)
      - two chambers in the middle are the sporangium (diploid)
      - inside the sporangium are the spores (haploid)
      - Might see additional tissue close to tip called calyptra (haploid)
      - Seta is the extension at the base (diploid)
  - - - string like protections are rhizoids
      - antheridia are small structures that surround sperm. Off to the side of structure (haploid)
      - sperm contained in antheridia (haploid)
    - - archegonia located at center of butterfly (haploid)
      - eggs are contained at the center of the butterfly (haploid)
    - - annulus is a protective ridged ring around sporangium (2n)
      - Sporangium is projection under the top of the tree (diploid)
      - spores are contained inside sporangium (haploid)
      - Indusium is the base (diploid)
