Terms in this set (15)
Learn the basic parts of the plant body.
o The vegetative (non-reproductive) parts of the plant
o The reproductive parts of the plant. Flowers & fruits
o Supports the plants and absorbs water and minerals
Learn the basics of flower morphology. Be able to identify and give the function of male and female reproductive structural parts of flowers.
Stamen (male): Anther and Filament
Carpel (female): Stigma, Style, Ovule, Ovary
Understand the fundamentals of pollination and fertilization in plants and learn the distinction between the two processes.
- Pollination: the placement or transfer of pollen from the anther to the stigma of the same flower or another flower
o Pollen grain lands on stigma and germinates; pollen tube grows into style
o Two sperm nuclei travel through pollen tube to ovary
o One sperm nucleus fuses with egg nucleus to form diploid zygote. The other sperm nucleus fuses with two polar nuclei to from triploid endosperm
Describe the formation and development of seeds and fruits.
Identify the basic structures of seeds and fruits and state the function of those structures.
Explore the basic processes of seed germination and identify the structures of developing monocot and eudicot seedlings.
Define plant meristems and differentiate between primary and secondary plant growth.
Distinguish the differences between monocots and eudicots at the level of flower, root, stem, and leaf tissues.
Examine the various tissues and cell types seen in stem and root cross sections.
Investigate the response of pea plant tissues to the presence of the plant hormone gibberellin.
Define tropism. Explore phototropism and gravitropism. Understand the role of the plant hormone auxin in tropism.
conduct substances to living cells
protest plant surfaces
store materials, function in photosynthesis, and structurally support the plant
Plants have 2 distinct stages in their life cycle
-the haploid gametophyte produces the male and female gametes by mitosis in distinct multicellular structures.
Fusion of the male and female gametes forms the diploid zygote, which develops into the sporophyte.
-after reaching maturity, the diploid sporophyte produces spores by meiosis. which in turn divide by mitosis to produce the haploid gametophyte. the new gametophyte produces gametes and the cycle continues
