Three types of plants that we should know
- Seedless Vascular (Produce Spores)
- Gymnosperms (Produce Cones)
- Angiosperms (Produce Flowers)
Give examples of seedless vascular
Ferns, horsetail, clubmosses
Conifers, cypress, gingko
To what class can be attributed
Gymnosperms
What are the subtypes of angiosperms? and their examples
- Monocots: Grasses, Palms, Orchids, Gingers
- Dicots: Cacti, Beans, Carrots, Sunflowers, Blueberries, etc.
What is sorus? sori-plural
a cluster of spore-producing receptacles on the underside of a fern frond
The cycle of pteridophytes (ferns)
The diploid generation is the sporophyte which produces the spores. The plant produces spores which are carried away by wind to far off places. Under favourable conditions these spores germinate into small independent gametophytes called prothallus.
The haploid generation is the gametophyte which produces the gametes.
Gamatophytes are multicellular and photosynthetic.
They bear male and female sex organs.
The sperm fuses with the egg resulting in the formation of zygote.
The zygote later develops into a multicellular sporophyte.
What is the common and Latin name?
Vase formation
- Ostrich Fern
- Matteuccia struthiopteris (L.) Tod.
What is this plant?
Horsetails
Equisetum arvense
The first picture is leaves
Last one - spores
What does gymnosperm mean?
What are some of their characteristics?
Naked sperm
Almost all are woody
Almost all are ever green
Seeds are not protected, when released from the corn
Gymnosperms found in tropics?
What is it? What about its juice
Fir tree
Have sticky juice -> antibacterial, not too hard to touch
what is it?
Spruce
What is it?
Hemlock
The name
Only one that loses needles
Tamarack
What is it?
Pine
Long soft needs
What is it?
Cedar
What is ginkgo? why is it strange?
Gymnosperm
It has male and female trees-> dioecious, female tree has fruits
It is too weak to survive in the wild
What is dioecious?
What is male and female parts on a plant?
Are most plants dioecious or monoecious?
- 90% of plants are bisexual: Monoecious
- ”Perfect” flowers have both male (Stamens) and female (Pistils) on the same flower
How to distinguish monocots from dicots?
Embryo, leaf venation, stems, roots, flowers?
Are those dicots or monocots?
Palms, mustard, mint, buckwheat, aroids, gingers, rose, irises, legumes, orchids, grasses (rice, wheat, corn)?
Monocots: grasses, palms, orchids, aroids, gingers, irises
Dicots: rose, legume, daisy, mustard, buckwheat, mint
Type of leaf arrangement
alternate
opposite
whorled
