- what does phloem do?
- assist in sugar doing down
- what is vascular tissue?
-
the plant tissue called xylem and phloem it is specialized for
the transport of water and nutrients - example of a protected gamete in a land plant

- what does moss need to live?
- a wet habitat
- Mosses lack these three things
-
vascular tissue
thick cuticle or stomata - how do mosses reproduce?
-
male sperm swims from male gametophyte; therefore ...
no water, no swim, no mo' moss. - what is the thallus?

main plant body o' moss
it's not organized into roots or shoots - what food does the thallus look like?
- corn flakes
- who has sporangia?
- both moss and ferns
- how do liverworts (marchantia) reproduce?
- sexually or asexually
- 3 examples of seedless vascular plants?
-
ferns
club mosses
horsetail - what are the three most important things that seedless vascular plants have?
-
vascular tissue
lignified tissue
depend on water for fertilization - what are the most common and successful seedless vascular plants
- ferns!
- what are fronds?
- leaves of ferns
- what does sporangia do?
- produce spores
- what are sori?
- spots on the bottom of ferns that contain the sporangia
- what's a rhizome?
-
a fern root--
it's like a stem, runs along/under ground - what are carboniferous forests?
-
vast swamp eras in the paleozoic era
now they are coal! - what happens when coal is burned?
-
carbon is released into the atmosphere as CO2
contributes to greenhouse effect - what types of plants dominate most landscapes?
- seed plants
- what did pollen eliminate the need for?
- water for fertilization
- what are the two groups of plants?
- gymnosperms and angiosperms
- what kind of seed do gymnosperms have?
- naked
- what are conifers?
- cone bearing plants-- evergreens
- what are needle-shaped leaves adapted for?
- dry conditions
- what are three types of conifers?
-
redwoods
Bristlecone (Methusaleh is 4600 y. old)
Pacific Yew (Taxol used for breast cancer treatment) - two other gynosperms
-
cycads- palm-like
ginko biloba - tell me about ginko biloba
-
it is a common city tree
smelly female treees-- better to plant males - what is coevolution?
- when two species evolve to benefit each other mutually-- mutualism
- what is mutualism?
- both benefit
- how did insects coevolve with flowers?
- they see yellow and blue flowers
- how did birds coevolve with flowers?
- they see red flowers and use tubular shapes or strong landing platforms for their beaks
- how did moths coevolve with flowers?
- they see white flowers
- why do angiosperms produce fruits and flowers?
-
they help them reproduce
it is an evolutionary adaptation - what are the major parts of a flower's anatomy?
-
anther, carpel, ovule, petal
pollen sepal stamen - what does the flower's anther do?
- produce pollen
- what is the stigma
- pollen tube
- examples of flowers made up of many flowers

- anthophyta
- how do conifers limit self-pollination?
-
the male have cones are on the outside
the female have cones on inside -
Five qualities of dinoflagellates -
1. Unicellular,
2. marine,
3. flagella,
4. toxins,
5. red tides (blooms) -

What can the bioaccumulation of dinoflagellates in shellfish cause? - PSP—Paralytic Shellfish Poisoning
-
Why dinoflagellate is called terrible - Many genera produce toxins, may become abundant (bloom/red tide), can harm fish and people
- Can dinoflagellates do any good in the world? If so, what?
-
They can light up surface water! Bioluminescence! -
