I just had a great idea: What if I posted my notes (of useful information) in Jiskha, so you could copy my notes and not fail OR cheat? I joined late so you'll only get some notes. Sorry.
i think tat is a great idea i also feel like some of the student like us who help should get paid for tis like we also have work of our own but we take time out of our day to help other jiskha could at least say thank because their tutors are no help
i get paid 5 dollars to 10 if my mom is feeling generous i should get paid more because i sweep mope and i mow the yard and rake and i wash the care that is worth like at least 25$ a week
4.2 Reproduction in Flowering Plants
Sepal: protects developing flower/supports when open (green/thicker than petals)
Petals: colorful, vary in dimensions, attract insects/birds, release chemicals animals can smell (humans too)
Stamen: male, anther (pollen production), filament (supports anther, slim stalk)
Pistil: female, ovary (large part underneath petal starting point/contains ovules), top part of pistil (stigma) gets pollen on it – sticky substance.
Stigma/ovary connected = long stalk (style)
Pollination: pollen moved between anther/pistil. Moved by wind, gravity, bees, birds, etc.
Fertilization (male/female cells), cells go through style into ovary and creates beginning of plant
Perfect flower: has stamen and pistil
Imperfect flower: only female or male, not both
Spikes cling to bee (pollen)
4.3 Reproduction in Non-Flowering Plants
Male cell must be able to swim to female one (damp places).
Sporophyte: most often seen stage/generation of plant that produces spores.
Spore: single cell produces plant without fusion with another cell.
Fern reproduce: underside of leaves get spores – land in damp place – grow into small gametophyte (makes gametes)
Gymnosperms (CONIFERS): pine, fir, cedar. Usually at sporophyte stage. Don’t need water, use wind and cones. Small cones (male) carry pollen. Large cones (female) carry female gametophyte.
Wind carries pollen male/female – gametes meet – become seeds – tree/sporophyte.
It won't show images I have in my notes :/
Sorry ya'll.
They're hiring, so I'm guessing everyone left them lol. I only get 5 dollars a week for chores (which is nice), but I am in no way gonna get enough money for a car in a short period. So getting paid on Jiskha would be verrryy nice.
4.4 Successful Plant Reproduction
Changes in flowers/pollinators over long time: coevolution
Pollination must occur for reproduction to be successful
And if anyone has something to add to my notes, just say the module/lesson (4.4) and I'll re-post it.
4.5 Successful Plant Reproduction
Courtship behaviors: male peacock spreads feathers, etc.
Successful courtship = reproduction
Territorial behavior: more access to resources if won (offspring > chance surviving)/mark territory (prevents intruders/fights), displays dominance
Mammals = more care needed
Courtship behavior: attracts opposite gender (as mate)
Animals (pollinators) help reproduce plants by getting reward (nectar, etc.)
Climate change/human activity = less successful reproduction
Stimulus: change in conditions (hibernate/migrate when cold/winter), response is reacton to stimulus
Grouping (group behavior): animals join other animals - group (wolves group - hunt), more complex: bee/ant roles, not all one thing
4.6 Analyzing Factors
Reproductive success: number animal can produce of offspring
Zoos breed, release, research endangered, conserve species
Surveying 3,000 children 1/3 got positive learning experience, 15% incorrect information
228 zoos: 30 species worked with for recovery (30 cases can’t be reintroduced).
Population size (all wolf packs in area), pack size (number of wolves in pack).
Patterns of change in graph: trends
5.1 Reproductive Strategies Introduction (11/10/2021)
Angiosperms: flowering plants
Sexual reproduction: gametes
Asexual reproduction: self reproduction, no gametes
