Terms Definitions
angiosperms
flowering plants
ROOTS
:Anchors plant:Absorbs water/minerals
moss
example of a bryophyte
Sori(Sorus)
reproductive structures of the fern
Cotyledon
the seed leaf; food resevoir
horsetails
seedless vascular palnts w/ scale-shaped leaves and hollow photosynthetic stems containing silica
alternation of generations
plant life cycle
Ginkgoales
Large trees with strange leaves; called maidenhair
phloem
plant vascular tissue that conducts sugars and other organic solutions
Cycadales
Look like palm trees; found in tropical regions
STRUCTURE of Ferns
1) Rhizomes2) Frond3) Sori(Sorus)-1- Sporangium
Transpiration
process to get rid of extra water
whisk ferns
early seedless vascular plants without true roots and leaves, but having rhizomes and photosynthetic branched stems w/ scale-like projections
Examples of CONIFERALES
Pines, Spruce, Firs, Seqouias, most are Evergreens
Seed Cones
woody cones that take several months to develop; contain seeds
stomata
opening in the lower epidermis of a plant leaf that allows carbon dioxide to enter leaf and oxygen and water vapor to leave
Pollen Cones
Smaller than seed cones; found on the tip of the branch; shed their pollen, and then fall of the tree
generations
alternation of_____
water
ferns reproduction requires______
FERNS
Gametophyte?
Sperm?
Sporophyte?
Dispersal?
Stems?
Vascular Tissue?
Roots?
Leaves?
Habitat?
-Independent, reduced photosynth
-motile
-dominant, independent photosynth
-spores (under leaves)
-lo vasc present (rhizomes-horizontal plant stem with shoots above and roots below serving as a reproductive structure)
-present
-present
-present (megaphylis fronds)
-mostly wet areas
most diverse plant group
angiosperms
plants
multicellular, eukaryotic, autotrophs; go through photosynthesis to make food from CO2 and water; have cell walls that support and protect cell; have a cuticle
haploid, diploid
_____ gametophytes alternate with_______ sporophytes
How do plants create food?
Photosynthesis
bryophytes
include mosses and their relatives that are sometimes described as nonvascular plants because they lack the lignin-hardened vascular tissue found in vascular plants. Don't have true roots; instead they have rhizoids which function in absorbing moisture and attaching the moss to a surface. The gametophyte is dominant generation.
All plants are photosynthesic since they contain __?
Chlorophyll
cellulose
polysaccharide that forms a tough fibrous meshwork in the cell walls of algae and plants
germination
to begin to grow or develop.
dermal tissue
major function: protection, covers the outside of a plants body
Pollen grain
A walled, immature gametophyte that will give rise to the sperm
coevolution
the process in which species exert selective pressure on each other and gradually evolve new features or behaviors as a result of those pressures
examples of nonvascular plants
mosses, liverworts, and hornworts
Ferns
12,000 species, have true stems, roots and leaves. most stems underground, leaves are called fronds
Pollinators
Animals (such as insects that feed on pollen) move pollen grains from male parts of one flower to female parts of another
Bryophytes are subdivided into what? (3)
Mosses, hornworts, liverworts
Liverworts
named for the capsule which looks like a human liver - wort means plant - over 8000 species
Non-vascular plants
A term used to refer collectively to the hornworts, liverworts, and mosses. All three are simple plants with no roots, stems, or leaves, and little or no vascular tissue. (also called 'bryophytes')
seedless vascular plants
An informal name for a plant that has vascular tissue but lacks seeds. Seedless vascular plants form a paraphyletic group that includes the phyla Lycophyta (club mosses and their relatives) and Pterophyta (ferns and their relatives).
What are the two main divisions of plants?
Vascular Plants and Bryophytes (non-vascular)
