-No ovary surrounding seed(ovules)
-"Naked seeds"
>Coniferophyta(largest group of gymnosperm):
>Cycadophyta:Florida coontie
(Zamia pulima), Sago palm
(Gingko biloba)
>Gnetophyta: Ephedra
-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
-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.
-Phylum Coniferophyta
-Gymnosperm(naked seeds)
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
is fertilization ovule. There are three parts
1)seed coat(2n)
derives from integuments
2)food supply
derives from megasporangium
or Nucellus
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?
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)
What is this plant? From what phylum?
-***Ginkgo biloba
-Phylum Ginkgophyta(ginko)
-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
-use for weightloss, semidesert plant, look alike horsetail and whisk fern
What is this plant? From what's phylum?
Phylum Anthophyta
(flowering plant)
(ovary surrounding seeds)
- 2 classes
> Monocotyledones(monocot)
> Dicotyledones(Dicot)
remember all these part of flower dissection!!!!
Carpel /Pistill(female part)
have 3 main parts
3.Ovary-cover ovule

have 2 mains parts
1.Anther-produce microspore>pollen>male gametophyte
"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
Class Monocotyledones
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
Monocots(Leaf venation)
-Veins usually parallel
Dicots(Leaf Venation)
-Veins usually netlike
-Floral organ usually in the multiples of THREE
-Floral organ usually in the multiples of Five
-Vascular tissue scattered
-Vascular tissue usually arranged in ring
-usually fibrous(no main root)
-Taproot(main root)usually present
