Flowering plants (angiosperms) are split into what 2 groups

Monocots and dicots

400

Eudicot flower structure characteristics.

- Two cotyledons -netlike veins -petals in fours/ fives - arrangement ringed in stem 

500

Monocot flower structure characteristics.

-One cotyledon -Parallel veins 

-Multiples of 3 petals -Vascular bundles in stem

200

Meiosis

Meiosis has a change in ploidy. (2n to 1n)

300

Mitosis

Mitosis has no change in ploidy. (2n to 2n) or (1n or 1n)

400

Challenges of Terrestrial life

Maintain water, obtaining resources, support, reproduction & dispersal of offspring. 

500

Plant kingdom- Four main groups

Bryophytes- nonvascular plants

Lycophytes & Pterophytes- seedless vascular

Gymnosperms- naked seed plants

Angiosperms- flowering plants 

Plant groups

100

Endosperm

Is the food source for the developing sporophyte embryo. 

200

Bryophytes characteristics 

Lacking vascular tissues, depend on diffusion and osmosis for the movement of water and minerals. Lack true roots, stems or leaves. Gametophyte dominant. 

300

Of the 4 major groups of plants, which group includes the ferns

Pterophytes

400

Sporophyte generation

Dominant, contains true vascular tissue, sporangial tissue is more developed. 

500

Gametophyte generation 

microscopic, undergoes alternation of generations, spores produced & dispersed by wind. Gametes produced & water dependent fertilization. 

Plant Structures

Diploid

(2n)

300

Reproductive chamber means...

Archegonia (female organ), antheridia (male organ)

400

Generation means either...

Sporophyte (produces spores), or gametophyte (produces gametes)
