Sporeeesssss
humus
decomposing organic material
vascular plants
body=sporophytes
produce drought resistant spores
filament
stalk of the stamen
negative
away from the stimulus
internodes
the stem segments between nodes
monocot
when vascular bundles are scattered
stigma
sticky knob that receives pollen
plants
multicellular eukaryotes that make organic molecules by photosynthesis and have acquired various adaptations permitting life land.
nutrient
element/molecule with essential role in an organism's growth and survival
Glomerulomycota
-all form endomycorrhizae called abruscular mycorrhizae
ovule
a female gametophyte develops inside an _____ which is a multicellular structure that is part of a sporophyte
Phloem
vascular tissue responsible for the transport of nutrients and the carbohydrates produced by photosynthesis
bulk flow
long-distance transport; the movement of a fluid driven by pressure. Water and solutes move through the tracheids and vessels of the xylem and through the sieve tubes of the phloem.
pericycle
outermost layer of the vascular cylinder of a root; where lateral roots originate
guard cells
pair that defines each stomata
development
series of stages in which tissues/organs/organ systems form in heritable patterns
mosses
leaves of moss gametophytes have blades nearly always one-cell thick and never lobed or dividednumerous chloroplatsaxis stemlike, without xylem or phloem
Casparian strip
-in endodermis of eudicot root
-contains suberin which forms waterproof seal
-regulates fluid and ion transport to vascular tissue
wilting
is a result of high transpiration rates (plant dehydration)
seed
a structure that contains the embryo of the plant
spirochete
member of a group of large spiral-shaped bacteria
application of chemiosmosis
transmembrane proton gradient links energy-releasing processes to energy-consuming processes in cells
tubers
enlarged ends of rhizomes or stolones; food storage
what is one feature of confier leaves
waxy
Gymnosperms
the "naked seed" plants, including the conifers
plant needs
sunlight, water and minerals, gas exchange, movement of wate and nutrients
Cork
Densely packed rows of dead cells. Protects, insulates, and waterproofs the stem/root surface
Peduncle –
the end of the flower stalk
Photoheterotroph
-an organism that obtains energy from light, but must obtain its carbon from organic substances
Parts of a coconut
White lining: endosperm
Dried Flesh: copra
Brown fur: Coir
Evidence that charophyceans are the closest relatives of land plants
rosette-shaped cellulose-synthesizing complexes, peroxisome enzymes, structure of flagellate sperm, formation of a phragmoplast, genetic similarities
Carnivorous Plants
Plants that trap & consume animals (Ex: venus fly trap)
initials
cells that remain as sources of new cells
the pistil consists of
a stigma, style and ovary
apical meristem
produces new cells near the root tip
hydrophobic
not dissolvable in water. ex: fats and oils are non polar molecules, so cannot interact with
Periderm
A type of dermal tissue that covers secondary growth stems and roots.
What is Bakane?
The foolish seedling disease of rice, which was found to be caused by the fungus Gibberella
turgor pressure
in living cells, when their water is under positive pressure, and cell contents press plasma membrane against the cell wall.
define polination
the transfer of pollen to the female gametophyte
vascular tissue system
distributes water and mineral ions as well as sugars from photosynthetic cells, consists of xylem and phloem
What is adjacent to every sieve tube element?
Companion cells
Name the four alternatives of plant geography
1-Antiquity of plant distribution.
2-Long-distance dispersal
3-Continental drift
4-Plants carried great distances anciently by man.
Problems/Terrestrial Adaptations2
-how to get water to cells
-how to get sex cells to travel so the sex cells can get together for sexual reproduction
What are members of Tomato family?
Bell pepper, curlipepper, tomato, egg plant
What is the function of root cortex?
Carbohydrate storage and water, mineral and oxygen trasversion
how do plants resemble algae?
they both use chlorophylls a and b and carotenoid pigments
List 4 examples of how plants respond to their enviornment through growth.
1. Flowers grow to bring sex cells together.2. Seeds grow for dispersal3. Phototropism (towards light)4. Gravitropism (towards or away from gravity)
