Kingdom Plante Outline





Chapter 27 - Kingdom Plantae
Objectives:
1) Discuss the human uses and the adaptations of gymnosperms.
2) Contrast dicots with monocots, and describe the life cycle of flowering plants.
3)Compare the various plant life cycles, and explain why angiosperms are more diverse
and widespread than the other plant groups.
4) Discuss the human uses and the adaptations of flowering plants.
Vocabulary:
gymnosperm - a vascular plant producing naked seeds, as in conifers. [gymn - naked,
sperm - seed]
dicotyledons (dicots) - woody or herbaceous and they have flower parts usually in fours
and five’s, net-veined leaves, vascular bundles arranged in a circle within the
stem, two seed leaves. [di - two, kotyl - cavity]
monocotyledons (monocots) - herbaceous and have flower parts in threes,
parallel-veined leaves, scattered vascular bundles in the stem, and one seed leaf.
[mono - one, kotyl - cavity]
angiosperm - a flowering plant, the seeds are borne within a fruit. [ang - vessel, sperm -
seed]
1a) Uses of Gymnosperms
- Supply much of the wood used for building and paper production.
- They produce valuable chemicals
1b) Adaptation of the Gymnosperms
- Well developed roots and stems
- Pollen grains are transferred by wind
- No need for to water to fertilize.

2) Contrast dicots and monocots
- See definitions
3a) Compare various plant life cycles
- Nonvascular Plants
* Dominant gametophyte
* Flagellated sperm
* Dependent sprorophyte
* Homospores disperse the species
- Seedless Vascular Plants
* Dominant sporophyte
* Homospores disperse the species
* Independent gametophyte
* Flagellated sperm
- Seed vascular plants
* Dominant sporophyte
* Heterosporous
* Dependent micro-, macrogametophytes
* Pollen grains
* Seeds disperse the species
3b) Why angiosperms are more diverse and widespread than the other plant groups.
- The fruit they produce gives a better covering for the seed to mature
- Animals eat the fruit then deficate somewhere else which
transports the seeds.
4a) Human uses of flowering plants
- food
- oils and spices
- medicinal drugs
4b) Adaptations of flowering plants
- true roots and stems
- vascular tissue is well developed
- broad leaves
