Plant Diversity | Bryophytes Flashcards
What were the earliest plants?
Non vascular plants
What are non vascular plants?
Seedless plants
What do non vascular plants lack?
Roots, stems, leaves
How do non vascular plants get their nutrients
They get it through diffusion from cell to cell
Where can non vasuclar plants be found
In moist areas
Are non vascular plants large or small
small
Are Gametophytes haploid or diploid
Haploid
Are Sporophytes haploid or diploid
Diploid
In non vascular plants can Sporophyte be separated from their maternal Gametophyte
No
What does the Sporophyte depend on the Gametophytes for?
Water and nutrients
For Sporophytes, do they use meiosis or mitosis?
Meiosis
For Gametophytes, do they use meiosis or mitosis?
Mitosis
What do Gametophytes produce?
Gametes (Sperm and Egg)
What do Sporophytes produce?
Spores
What are the 3 groups of Bryophytes
1) Mosses
2) Liverworts
3) Hornworts
How are bryophytes dispered?
Through the wind as they are very light
Where are bryophytes mostly located
Moist forests and wetlands
How can a moss retain it’s moisture?
They can go dormant during a drought and reactivate its cells when moisture becomes available
What does the Sporophyte of a Moss consist of?
The foot, stalk, and sporangium
Define the Sporangium
The site where meiosis and spore reproduction happen
Are hornwort Sporophytes long lived or short lived?
Long lived
Are Liverworts Sporophytes long lived or short lived?
Short lived
What is the most dominant phase of the Bryophyte cycle
Gametophyte
How does the Gametophyte reproduce?
Sexually
