Cards

Term
What are the three main characteristics of plants?
Definition

1. Multicellla

2. Photosynthetic

3. Eukaryotes

Term
What is the evolution of plants marked by?
Definition
Evolutionary adaptations to land
Term
waht aquatic green algae is most closely related to land plants?
Definition

Charophytes

 

(they have retention of and care of the zygote)

Term
According to the lab introduction, what does vascular tissue offer plants?
Definition
Support and transport (water and nutrients) to and from the leaves, roots, and stems. 
Term
Nonvascular and seedless vascular plants rely on what for reproductive purposes?
Definition
An outside source of water
Term
What are the 5 significant innovations of plant evolution?
Definition

1. Embryo Protection

2. Vascular Tissue

3. Megaphylls

4. Seeds

5. Flowers

Term
What are the 3 Bryophytes of which are examples of Nonvascular plants?
Definition

1. Liverworts

2. Hornworts

3. Mosses

Term
What are the 2 types of seedless vascular plants?
Definition

1. Lycophytes

2. Ferns and Allies

Term
Alternation of generations involves what? 
Definition

Sporic Meiosis 

 

(remember Meiosis is when the cell splits into 2 daughter cells that are haploid)

Term
The sporophyte generation is Diploid and produces what?
Definition
Produces haploid spores by meiosis. The spores develop into a Haploid generation. 
Term
What do non-vascular plants not have that are very important to vascular plants?
Definition

1. Xylem

2. Phloem

Term

Phylum

 

Mosses

Definition
Bryophyta
Term

Phylum

 

Liverworts

 

Definition
Hepatophyta
Term

Phylum 

 

Hornworts

Definition
Anthocerophyta
Term

Phylum

 

Lycophytes

&

Club Moses

Definition
Lycophyta
Term

Nonvascular plants

 

the eggs are produced by the (blank) generation. 

Definition
Gametophyte
Term

Nonvascular plants

 

where are the eggs produced? 

 

(mosses)

Definition
Archegonia
Term

Nonvascular Plants

 

where are the flagellated sperm produced?

Definition
Antheridia
Term
Land Plants are known as (blank)
Definition
Embryophytes
Term
By definition, roots, stems, and leaves have what?
Definition
Vascular Tissue
Term
Land Plants
Embryophytes
Definition
Alternation of generations
Multicellularsporophyte embryo is protected
Ametangia produce gametes
Apical tissue produces complex tissues
Waxy cuticle prevents water loss
Term
Bryophytes
Definition
Nonvascular
Liverworts (Hepatophyte)
Hornworts (Anthocerophyta)
Lycophytes/ club mosses (Lycophyta)
Term
Vascular Plants
club mosses, ferns and their allies, seed plants
Definition
Branched Sporophyte has vascular tissue
Lignified xylem transports water
Phloem transports organic nutrients
Gametophyte is dependent on Sporophyte
Has roots, stem, leaves
Term
Lycophytes
(Club Mosses)
Definition
Leaves are Microphyllswith 1 vein
Sporangia borne on sides of leaves produce windblown spores
Independent and separate gametophyte produces flagellated sperm
Term
Ferns and Allies
(
Pteridophytes
Definition
Leaves are Megaphyllswith branched veins

DominantSporophyte produces windblown spores in sporangia born on the leaves

Independent and separategametophyteproduces flagellated sperm
Term
Seed Plants
( Gymnosperms and angiosperms )
Definition
Leaves are Megaphylls
Dominantsporophyte produces heterospores that become dependent male and female gametophytes
Male: Gametophyte = Pollen Grain
Female: Ovuleà becomes a seed
Term
Gymnosperms
Definition
Cycads, ginkgoes, conifers, gnetophytes
Largeà Cone Bearing
Sporophyte bears pollen conesà windblown pollen
Seed cones bear ovulesà naked seeds
Term
Angiosperms
( Flowering Plants )
Definition
Diverse
Live in all habitats
Sporophyte bears flowersàpollengrainsàbear ovules within ovary
Double Fertilization, ovules become seeds that enclose a sporophyte embryo and endosperm
Fruit developes from ovary
Term
The group of seedless vascular plants include which phylums?
Definition

1. Lycophytes

2. Pteridophytes

~Club Mosses

~Whisk Ferns (Psilotum)

~horsetails (Equisetum)

~Ferns (Filicales)

Term
Which generation is dominant in Seedless Vascular Plants?
Definition
Sporophyte is Dominant
Term
Dominant Sporophyte Generation for seedless vascular plants has what land adaptations?
Definition

Vascular Tissue

Produces Windblown Spores that develop into separate gametophyte generation

Term
The gametophyte generation of seedless vascular plants lack (blank) and produce (blank) .
Definition

Lack: Vascular Tissue

Produce: Flagellated Sperm

Term
Microphylls 
Definition
Leaves that have only one strand of vascular tissue
Term
terminal cluster of leaves on ground pines are called what
Definition

Strobili

 

club shaped

bear sporangia

Term
what does the pigment "Sporopollenin" do for plants
Definition

protects against UV radiation

and desiccation

Term
Lycopodium (Lycophytes) are (blank) meaning they produce one type of spore. 
Definition
Homosporous
Term
Why do nonseeded plants need an outside water source for reproduction
Definition
They need water because they produce flagellated sperm
Term
The spike moss "Selaginella" produces 2 types of spores called (blank) and (blank) that develop separetly into (blank) and (blank)
Definition

Microspore: male gametophyte

Megaspore: female gametophyte

 

Selaginella is "Heterosporous"

Term
Psilotum have no (blank)
Definition
They do not have leaves
Term
The underground stem of a Psilotum called "Rhizome" give off (blank) with (blank) branching pattern where sporangia are located
Definition

give off upright, aerial stems 

with a dichotomous branching pattern

Term
Equisetum contains (blank) on its stem that gives it it's name "Scouring Rushes"
Definition
Silica (existant on its stem)
