Land plants believed to have arisen from... |
GREEN ALGAE. Specifically: Charophytes |
|
|
Phylum Brophyta (Mosses) BRUUUH |
Simple and small Gametophytes (dominate) + Sporophytes (smaller) = THALLUS
Reproduce by SPLASH CUP. Swim and BOOM! BRUUUUH
Gametophyte has rhizoid at base
SEE DIAGRAM |
|
|
Brophyta (mosses) SPERM cell made in...
|
ANTHERIDIA |
|
|
Brophyta (messes) EGG cells made in... |
ARCHEGONIA The eggs reside under the rock!!!!!! |
|
|
Phylum PTEROPHYTA (FERNS) |
Sporophytes dominate Gametophytes Smaller THALLUS = Only the Gametophyte Has True Leaves (FRONDS). True Roots. Is a TRUE PLANT Fronds have stomata and a cuticle(waxy covering) Still like moist habitats |
|
|
THALLUS (like... fake plant) |
Most cells v similar. NO Specialized tissues, cuticle, stomata. Has rhizoids (insteada true roots) often whole structure can photosynthesize! |
|
|
True Plant |
Many diff tyoes of cells HAS specialized cells, cuticle, stomata Has true roots Usually leaves photosynthesize |
|
|
Phylum CONIFEROPHYTA (CONIFERS) |
Sporophyte dominant GAMETOPHYTE PRODUCED IN CONES. seeds in female cones
|
|
|
Phylum CONIFEROPHYTA (CONIFERS) - POLLEN GRAINS aka... |
...sperm cells. |
|
|
Phylum CONIFEROPHYTA (CONIFERS)- Fertilization |
POLLINATION. (POLLEN GRAINS TRANSFERED BY WIND to the female cones). |
|
|
Phylum ANTHOPHYTA (FLOWERING PLANTS) |
Make up most of the plants living on earth today. Sporophyte dominant. ALL produce FLOWERS and SEEDS. Seeds develop in fruits
|
|
|
Functions of Parts of a Flower - SEPALS |
ENCLOSE and PROTECT the developing flower. Often photosynthesize. EX: tulips |
|
|
Functions of Parts of a Flower - PETALS |
Often brightly colored to attract, for ex:, Bees for POLLINATION. May be smaller or absent in pollinated flowers. |
|
|
Functions of Parts of a Flower - STAMEN |
like.. SEMEN Produce MALE gametophytes. (MICRO gametophytes) |
|
|
Functions of Parts of a Flower - Carpels |
Produce FEMALE gametophytes (MEGAgametophytes) |
|
|
Nectar |
Also functions in attracting pollinators. (in addition to petals) |
|
|
Fruit: ovule develops into... |
seed |
|
|
Fruit: ovary develops into... |
fruit. |
|
|
fruit: meiosis in ANTHERS... |
sperm
|
|
|
fruit: meiosis in OVULES |
egg` |
|
|
Pollination is via:.. |
Wind, animals, or water |
|
|
Fruits (fleshy or dry) transfered by....
(or seeds).. |
Wind, animals, attaching to animals, in animals digestive tract, floating on water.
UNUSUAL: frocible/explosive discharge. |
|
|
Dormant Seeds |
Alive but not actively growing. Some can remain this way for years. |
|
|
Seed germination: GERMINATION |
the early stages of growth of the embryo.
eventually grows into a new sporophyte. :) |
