Index
We can classify plants in 2 ways:
1-*Vascular plants *NON-vascular plants
2-*Flowering plants *NON-flowering plants
Classifying plants
Vascular plants(Gymnosperms
)They have roots and Phloem and Xylem, tubes through which sap goes, so they take the water and nutrients from the soilExamples : fir,Pinetree,cypress…..They reproduce with SEEDS
NON-vascular plants
(Mosses)They do not have roots , Phloem or XylemSo they take the water from the enviroment because they have especial leavesThey have like roots but not to take the water, they have that to stick in many placesThey reproduce with SPORES
Vascular and NON-vascular
plants
Flowering plants
(Angiosperms)
The most numerous groupThey have beautiful, scent, big flowers, they grow with seeds insideExamples : lavender,apple tree…
NON-flowering
plants(Ferns)
Mostly found in forests , they love dark and humid places , also coldThey reproduce with SPORES
Flowering and NON-flowering
plants
There are 3 types of plants :The plants that only have the male part( the STAMEN )The plants that only have the female part( the PISTIL )The plants that have the male and female parts ( the 2 things )
Sexual reproduction
They are 2 types of pollination :Insect pollinationWind pollination( I am going to explain that later )
Types of pollination
There are 5 types of Asexual reproduction :CuttingGraftingRhizomes ( these are specialized stems that grow underground )Stolons ( specialized stems that grow above ground )Tuber : potatoes grow new plants . They also are specialized underground .
Asexual reproduction
1 flowers have pollen on the top of the stamens2 the pollen smells delicious to insects 3 insects eat pollen and sticky nectar so… the pollen travels inside the pistil because insects take pollen everywere!4 when the ovule touches a NEW SEED is growing
Insect pollination
