Gymnosperm
|
-No ovary surrounding seed(ovules)
-"Naked seeds" -Phylum >Coniferophyta(largest group of gymnosperm): Pinetree(Pinus) ,Firs,Spruce,Hemlock >Cycadophyta:Florida coontie (Zamia pulima), Sago palm >Ginkgophyta:Gingko (Gingko biloba) >Gnetophyta: Ephedra |
|
|
Angiosperm
|
-Ovary surrounding seeds
-Phylum Anthophyta(flowering plants) have 2 classes 1) class Monocotyledones 2) class Dicotyledones |
|
What is structure No.1 and No.2? What is this plant? Phylum?Kingdom?Domain?Gymnosperm or Angiosperm?
|
-No.2 " Ovulate cone* or Pistillate cone*"(female)
-No.1 " Pollen cone* or Staminate cone*" (male) -It's Pinetree (Pinus) -Phylum Coniferophyta -Kingdom Plantae -Domain Eukarya -Gymnosperm |
|
|
-Ovulate Cone or Pistillate cone
-Contains megaspore>female gametophyte>eggs(n) -It is composed of scales(modified leaves)sometimes called sporophyll; the seeds were between the scales. Note: Sporophyll-a modified leaf that produces spores |
What is this organism?What is its functions?
|
|
|
-Brown one is "**Pollen cone or Staminate cone".
-Contains microsporangium ->male gametophyte(pollen grains)->sperm(n) Note: little brown dot is Sporophyll(modified leaf) -Green one is Pine needles(leaves)->adapted to wild conditions Notes: In Pinetree, the male gametophyte is pollen grain. There is no Antheridiun. |
What is the brown organism in the picture? What is the green part called?
|
|
What is this structure?Why is it important? Which plant has this structure?
|
-Pinus Pollen(pollen grain of Pinetree;Pinus)
-Pollen Grains have bladders or **wings which help them float on air currents.and they also have pollen tube. -Pinetree(Pinus*) -Phylum Coniferophyta -Gymnosperm(naked seeds) |
|
Ovule
|
is a structure found in seed plants that develop into a seed after fertilization.
There are three parts to consider as an ovule. I. Megaspore II.Megasporangium/Nucellus III.Integument |
|
|
Seed
|
is fertilization ovule. There are three parts
1)seed coat(2n) derives from integuments 2)food supply derives from megasporangium or Nucellus 3)Embryo(2n). It's new sporophyte |
|
This is a section of a leaf(needle) of Pinus. What is No.1,No.2,No.5,No.6, No.7?
|
1.Stoma
2.Endodermis 5.Epidermis 6.Phloem:conduct food or sugar-up 7.Xylem:conduct water and minerals-down |
|
|
dont worry too much
|
look at young stem of Pinus(pinetree)be responsible for components
|
|
What is this plant? What is genus and species? Phylum? Gymnosperm or Angiosperm?
|
-Florida coontie(common name)
-Zamia pumila -Phylum Cycadophyta -Gymnosperm(naked seed) |
|
|
-Sago palm
-Phylum Cycadophyta(Cycads) -Have a large cone and palmlike leaves(true palm species are Angiosperm) -Gymnosperm* |
What is this plant? From what phylum?
|
|
|
-Ginkgo
-***Ginkgo biloba -Phylum Ginkgophyta(ginko) -Gymnosperm -Oxiginate to the brain(inceasing memory) -flesh seed contains Butyric acid -fan shape leaves -Note: in the pic are male and female reproductive structures and seed |
What is this fan shaped plant? Name species and genus? From what phylum?
|
|
|
-It is "Ephedra"
-Phylum Gnetiphyta -Gymnosperms -use for weightloss, semidesert plant, look alike horsetail and whisk fern |
What is this plant? From what's phylum?
|
|
|
Phylum Anthophyta
(flowering plant) |
-Angiosperm
(ovary surrounding seeds) - 2 classes > Monocotyledones(monocot) > Dicotyledones(Dicot) |
|
remember all these part of flower dissection!!!!
|
Carpel /Pistill(female part)
have 3 main parts 1.Stigma 2.Style** 3.Ovary-cover ovule Stamen(male) have 2 mains parts 1.Anther-produce microspore>pollen>male gametophyte 2.Filament |
|
"Double Fertilization"
|
-Happen in Angiosperm&a few Gnetophyte
-2 sperms nuclei are discharged > one with a nuclei in embryo sac, making "embryo" >another one with central nuclei( two eggs(n)), making food supply called "Endosperm(3n)" -embryo sac contains 8 haploid nuclei in 7 cells |
|
|
-have a single small cotyledon
-Ex.corn |
Class Monocotyledones
(Monocots)-seed |
|
Class Dicotyledones
or Dicots(seed) |
have two cotyledons that
are attached to the embryonic plant. These leaf-like structures contain most of the nutrients from the endosperm -Ex.bean |
|
Monocots(Leaf venation)
-Veins usually parallel |
Dicots(Leaf Venation)
-Veins usually netlike |
|
Monocots(Flowers)
-Floral organ usually in the multiples of THREE |
Dicots(Flowers)
-Floral organ usually in the multiples of Five |
|
Monocots(Stems)
-Vascular tissue scattered |
Dicots(Stems)
-Vascular tissue usually arranged in ring |
|
Monocots(roots)
-usually fibrous(no main root) |
Dicots(roots)
-Taproot(main root)usually present |
