Bryophyta Flashcards
(23 cards)
What is the Kingdom Plantae?
A classification of multicellular, autotrophic organisms that have a cell wall made of cellulose.
What are some examples of plants?
- Trees
- Flowers
- Herbs
- Bushes
- Grasses
- Vines
- Ferns
- Mosses
What are the general features of plants?
- Autotrophic
- Eukaryote
- Some plants are mutualistic
- Asexual and sexual reproduction
How do plants differ from fungi?
Plants are generally autotrophic multicellular phototrophs gaining carbon through photosynthesis, while fungi are heterotrophic uni- or multi-cellular saprotrophs.
Do plants move?
Most plants do not move from one place to another but can grow and move towards light.
What is unique about carnivorous plants?
They can move rapidly due to quick changes in cell size.
What are the habitat requirements for most plants?
- Soil
- Water
- Free oxygen
- Light
What is the significance of the rigid cell wall in plants?
It is made of cellulose, which is a defining characteristic of the Kingdom Plantae.
What is the Phylum Bryophyta?
A group of non-vascular plants including liverworts, hornworts, and mosses.
What are the characteristic features of Bryophyta?
- No vascular bundles
- No true roots, stems, or leaves
- Alternation of generations with gametophyte more visible than sporophyte
What are rhizoids?
Structures in Bryophyta that act like roots but are not true roots.
What is alternation of generations in Bryophyta?
A life cycle that includes both haploid gametophyte and diploid sporophyte generations.
What does the sporophyte generation produce?
Zygote and seta with a capsule, which later undergo meiosis to produce spores.
What are archegonia and antheridia?
- Archegonia: female structures
- Antheridia: male structures
What is protonema?
A haploid structure that is part of the gametophyte generation.
What is the role of mosses in the ecosystem?
Mosses act as pioneer plants, making soil and preventing erosion.
What is Sphagnum palustre known for?
It forms peat and lives in bogs or wetlands.
Fill in the blank: The life cycle of Bryophyta includes alternation of generations between __________ and __________.
gametophyte; sporophyte
True or False: All plants are vascular.
False
What is the significance of mosses in decorative purposes?
Mosses are used for both interior and exterior decoration.
What is the habitat of Merchantia polymorpha?
Lives in forests near water and is dioecious.
What is the tallest moss mentioned in the text?
Polytrichum commune
