|fibrous root system||
Innermost layer of cortex
vascular bundles in leaves
Food for germinating seed
stores and digests reserve materials
Tip of the stem
-have secondary cell walls strengthened by lignin
-often dead at functional maturity
-found in part of plant that has stopped growing
-fiber cells and sclereids
A rapidly growing, asexually reproducing fungus.
Male reproductive structure in plants.
main component of phloem sap
vascular plant tissue consisting mainly of tubular dead cells that conduct most of the water and minerals upward from roots of the rest of the plant
vascular, xylem/phloem, true leaves roots stems, spores (gametangia)
male:antheridia wim flagellated
female: archegonium, zygot-sporophyte 2n
produces eggs in bryophytes and ferns
-Function: Support the plant, synthesize and store organic products
-least specialized of plant cells
-primary walls are thin and flexible
-lack secondary cell wall
-large central vacuole
|abscicic acid (ABA)||
inhibits growth; seed dormancy
point at which leaves are attached
lateral roots; under surface of ground
both staminate (male) and pistillate (female) flowers occur on the same plant
vascular tissue responsible for the transport of nutrients and the carbohydrates produced by photosynthesis
hole made by puncturing a surface
another way plants can reproduce asexually; this involves grafting the tissues of two plants together
embryonic tissue that aids in indeterminate growth
primitve vascular - overlap with pores
haploid plant, because it produces haploid gametes and these gametes then combine to form a diploid plant
anchoring the plant, absorbing mineral and water, storing organic nutrients
Cells within the vascular cambrium that produce xylem and phloem rays, radial files that consist mostly of parenchyma cells.
|primary tissues of roots (3)||
Living cells at maturity that transfer sugar and photosynthesis products throughout plant
lack one or more floral parts
|4 organs of flowers||
sepals, petals, stamens, carpels
A short, wide, water-conducting cell found in the xylem of most angiosperms and a few nonflowering vascular plants. Dead at maturity, they are aligned end to end to form micropipes called vessels.
Long tubular single cells or filaments of cells that anchor bryophytes to the ground.not composed of tissues, they lack specialized conducting cells, and they do not play a primary role in water and mineral absorption.
The structures that contain the immature male gametophytes.
living parenchyma cells that lie adjacent to sieve-tube members
refers to how plants respond to touch
Transports materials between the roots and shoots
formed from the original zygote; continually divides to form the suspensor
transport of organic nutrients in a plant
|A microscopic pore surrounded by guard cells in the epidermis of leaves and stems that allows gas exchange between the environment and the interior of the plant.||
|sieve tube elements and companion cells||
responisble for the vertical growth of the plant
thickening of roots and shoots (at lateral)
elongated and occur in bundles (cell types)
lateral meristem that adds layers of vascular tissue called secondary xylem and secondary phloem
A naked, asexual spore produced at the ends of hyphae in ascomycetes.
A physiological cycle of about 24 hours that is present in all eukaryotic organisms and that persists even in the absence of external cues.
internal clock that continues to keep time
plants which require short periods of darkness
cells that stay as sources for new cells
|vascular tissue system||
carries out long distance material transport btw. roots and shoots
|sieve tube members||
transport sugars and nutrients between sources and sinks
dont have mito ribo or nucle so campanion cells maintian
|GYMNOSPERMS AND ANGIOSPERMS||
the seeded plants and what tracheophytes can be further divided into
in flowering plants, the lower part of a pistil that produces eggs in ovules.
|Cyclic Electron Flow||
The process in which electrons are transferred only by light reaction, in which case they are recycled from ferredoxin back to the intermediate carriers.
joining of haploid gametes to create a diploid zygote, and the simultaneous joining of a second sperm cell with a fusion nucleus to create a triploid nucleus (which becomes the endosperm).
* flower parts in groups of 3's
* leaf: parallel vein network
* 1 seed coat
* scattered vascular bundles in stem
ex. irises, tulips, daffodils
A mycelium formed by the fusion of two hyphae that have genetically different nuclei.
refers to parent plants which are able to reproduce asexually, that is, using leaves, stems or roots to produce another plant
|how does PS 1 work||
postive charge attracts depleted electrons
energeticelectrons used to reduce ndap+ to nadph
|day nuetral plant||
light does not affect the flowering of a plant
|closes stomata, inhibits growth, seed dormancy, withstand drought||
functions of abscisic acid (4)
|cell division, elongation, differentiation||
zones in the stages of primary growth, from tip to the interior
|zone of maturation or differentiation||
zone of primary growth in roots where cells complete their differentiation and become functionally mature
