Plants are __________ organisms that evolved from semi-aquatic __________.
All land plants derived from __________ __________
All plants are: __________, __________, __________, and __________.
Multicellular, eukaryotic, photosynthetic, and cell walls contain cellulose
__________ are the closest land plant relative.
__________ often inhabit shallow, ephemeral waters.
Shared characteristic #1 between plants are charophyceans:
Rose-shaped complexes for cellulose synthesis
Rose-shaped complexes for cellulose synthesis (in plants and charophyceans) instead of __________ complexes.
Shared characteristic #2 between plants and charophyceans:
Similar peroxisome enzymes
Plants and charophyceans have similar __________ enzymes.
Shared characteristic #3 between plants and charophyceans:
Similar flagellated sperm structure
Shared characteristic #4 between plants and charophyceans:
Phragmoplast forms during cell division
Non-vascular plants dominated for ________.
Land plant invasion was during the __________ period.
The Ordovician period was __________
Terrestrial adaptations of plants include the formation of __________ and __________.
Epidermal polymers that act as waterproofing are called:
__________ is a durable polymer that prevents spores/pollen from drying out.
__________ kept plants from desiccating in an arid environment.
Embryonic plant tissue in the tips of roots and buds of shoots. The dividing cells of this enables plants to grow in length.
A life cycle in which there is both a multicellular diploid form, the sporophyte, and a multicellular haploid form, the gametophyte; characteristic of plants and some algae.
Alternation of generations
The 5 unique plant characteristics are:
Apical meristems, alternation of generations, walled spores in sporangia, multicellular gametangia, and multicellular dependent embryos
A gamete producing organ
The process in which each generation gives rise to the other.
Alternation of generations
Multicellular sporangia that produce spores with __________-enriched walls are key terrestrial adaptations of land plants.
Localized regions of cell division at the tips of roots and shoots:
Shoot apical meristems generate __________ in most plants.
In bryophytes, the __________ is the dominant life stage.
Bryophytes are __________, _________ plants.
Non-vascular, seedless plants possess:
Antheridia and archegonium
A __________ grows from the archegonium.
Reproduction in non-vascular, seedless plants is __________ dependent.
Reproduction in non-vascular, seedless plants is water dependent due to what?
Bryophyte taxa is made up of:
Liverworts, hornworts, and mosses
The fact that the reproduction of non-vascular, seedless plants is dependent on water limits it range to:
Non-vascular, seedless plants are __________ in size.
Sugar/organics transport. Transports products of photosynthesis.
In vascular plants, the __________ is the dominant life stage.
__________ anchor plants, absorb nutrients, and provide support.
Vascular plants have _________ and __________.
Roots and leaves
__________ __________ alleviates size constraints.
Dots of ferns:
__________ __________ increases surface area for photosynthesis.
Spine-shaped leaf with a single strand of vascular tissue.
Broad leaf with a vascular network.
_________ are evolved by branch webbing.
Modified leaves that bear sporangia.
When a single spore gives rise to both male and female plants, it is:
When the megaspore becomes female and the microspore becomes male, the plant is:
Most seedless plants are:
All seed plants are:
__________ __________ transformed land and the atmosphere.
