-Due to the lack of this tissue, these plants develop no stem and as such are usually short since they have no way to move water and nutrients through them.
-Instead, they can just diffuse water and nutrients since they either live in water or in moist areas.
Seedless
Nota:
Use spores but no seeds to reproduce.
Ferns
Nota:
-Like moist areas bur can adapt to drier areas.
-Require moisture for reproduction.
-Larger in size compared to other seedless plants.
Angiosperms
Nota:
-Flowering plants with both reproductive parts (male and female).
-Pollen is dispersed by wind and animals alike.
-Their seeds are covered by fruit which protects them and helps with dispersion.
- Life cycles of annual(grows and blooms once, then die), Perennial (Blooms once and then goes dormant before growing and blooming again), and Biennial (grows twice a year before blooming and then dies).
Seeds
Nota:
-Pollen fertilizes the ovules and a seed is produced.
-Embryo with food source in protective covering.
-Already fertilized.
-Can stay dormant if the environment is unfavorable.
Monocots
Nota:
-They are also their own kind of clade.
-Vascular bundles are spread all round the stem.
-Pollen has 1 pore(hole).
-Parallel lead veins.
-Floral parts in sets of 3s.
-One Cotyledon(Leaf of the seeds embryo).
Dicots
Nota:
-Vascular Bundles are organized into a ring.
-Floral parts in sets of 4s or 5s.
-Net-like leaf veins.
-Pollen has 3 pores(holes).
-Has 2 cotyledons (leaves of the seed embryo).
2 Mayor Groups
Amborella
Magnoliids
Eudicots
Clades
Water Lilies
Gymnosperms
Nota:
Each one only has one reproductive part (male or female).
Rely on wind for dispersion of sperm cells.
Vascular
Tissue
Nota:
-Specialized tissue for transportation and storage of water and nutrients.
-It also gives support to the plant and allows it to develop a stem.
+Since they grow a stem, some of them also get bark and wood and become trees.- As such, they can live in drier environments than non-vascular plants.
