nonvascular, mosses, liverworts, no vascular tissue,( no roots leaves or stems) low lying, spores, GAMETOPHYTE DOMINANT
|
|
Pterophytes
|
Vascular Plants, ferns, club mosses, vascular tissue, roots leaves and stems, well developed fronds, spores, SPOROPHYTE DOMINANT
|
|
Gymnosperms
|
Vascular, naked seeds, conifers, vascular tissue, roots leaves, and stems, woody trees, needles, seeds SPOROPHYTE DOMINANT
|
|
Vascular System Parts
|
Xylem- From roots to leave
Phloem- From leaves to roots or roots to leaves Where ever the plants need the material |
|
Reproductive Systems
|
Gametophyte (1n Haploid)
Sporophyte (2n Diploid) |
|
Gametopyhte
|
1n Haploid, plants produce the gametes that fertilize and make the sporophyte
|
|
Sporophyte
|
Produces spores that make the gametophyte (2n diploid)
|
|
1n Haploid
|
Reproductive cells, half the number of chromosomes
|
|
2n Diploid
|
full amount of chromosones
|
|
Alteration of Generation in Mosses
|
Gametophyte turns into sporophyte,
|
|
Whisk Ferns or Psilophyta
|
No roots or leaves, reproductive structures at the end of branches
|
|
Club Mosses
|
Evergreen, produces spores in cones, have roots.
|
|
Sphenophyta, Horsetails
|
Jointed Stems, outer cells contain silica
|
|
Pteridophyta/ Ferns
|
Leaves, underground stem, spores under leaves
|
|
Gymnosperm Plant Structure
|
Do not need water to reproduce they use air, Plants produce gametes to fertilize and make sporophyte, produces seeds, does not produce flowers, seeds usually made in cones
|
|
Angiosperm
|
seeds made in fruit, flowering, use animals to pollenate, sporophyte dominant
|
|
Annual, biannual, perennial
|
lasts one year, lasts two years, comes back until it dies
|
|
Phosolipids
|
made of phosphates and fatty acids, found in the cell membrane and push through water
|
|
Transport Proteins
|
Allows larger things to move through the phospholipids, made of ribosomes
|
|
Chloroplasts
|
have their own DNA and ribosomes
|
|
Mitochondria
|
has its own DNA and ribosomes
|
|
Wood rings
|
Consist of late and early wood. They can be used to tell age or climate of the years they were alive. All rings contain the same amount of cells
|
|
Early wood
|
light wood produced in the spring
|
|
Late wood
|
dark wood produced in late summer
|
|
Gymnosperm wood
|
less condense than angiosperm wood
|
|
angiosperm wood
|
most condensed wood
|
|
Flower
|
formed by the gametophyte and produces fruit. ANGIOSPERMS ONLY
|
