Vascular-Non Seed Bearing Plants

Front 1

Vascularization in plants (non seed-bearing).
-water and minerals are associated with?
-sugars, amino acids and other organic matter is associated with?
-what main structure does vascularity allow for?

Back 1

-xylem (dead cells)
-phloem
-roots

Front 2

Phylum Lycophyta (the club mosses)
-which life cycle generation is dominant
-what is interesting about the sporangia?
-does it hold a symbiotic relationship with any other organism?
-What is its method of reaching sporehood

Back 2

-sporophyte (gametophyte is a sepereate plant)
-exists in a structure called a stobili
-the gametophyte is nurtured by a fungi
-megaspors and microspores?

Front 3

How does the the sporophyte produce the egg and sperm in each
a.) homospore
b.) heterospore

Back 3

a.) sporophyte->single type of spore->bisexual gametophyte
->eggs
->sperm
b.) heterospores
->megaspore->female gametophyte->eggs
->microspore->male gametophyte->sperm

Front 4

phylum Pterophyte: Psilophyta:
-What is it's common name
- what life stage dominates?
-describe its vascularity
-describe the branching pattern and what is the term?
-where is the gametophyte?
-what is the nature of the sporangia?
-What method to reach to sporehood.

Back 4

-Whisk ferns
-Sporophyte
-It possess partial vascularity
-dichotomous- branch from a branch
-Gametophyte exists as a seperate entity
-the sporangia appear as nodules
-Homosporous

Front 5

Phylum Pterophyta: sphenophyta: the horsetails
-What is the common name of this phylum
-what is the relation between the sporophyte and the gametophyte
-describe its method of reaching sporehood
-what is in its epidermis?

Back 5

-Horsetails
-the gametophyte is a small photosynthetic organism
-homosporous
-silica

Front 6

Phylum Pterophyta:- the true ferns
-Leaves?
-what is noteable about the sporangia?

Back 6

- the true ferns
-large compound leaves called fronds
-they are in clusters called sori found under fronds

Front 7

Strobili
-To which phylum does this belong
-What is interesting about the structure of this apparatus

Back 7

-Belongs to lycophyta, the club mossess
-Sporangia occur on a leaf like structure called :sporophylls (a cluser of which is called a strobilis)

Front 8

Major shifts in plant alternation of generations
-Explain what happens to the gametophyte while progressing up the phylogenetic history

Back 8

- In bryophytes, the sporophyte was dependent upon the gametophyte

-In Vascular, non-seed bearing plants such as ferns, the gametophyte was much smaller, and existed as seperate entity

-In seed-bearingvascular plants the gametophyte is dependent upon the sporophyte
