What 4 characteristics do all plants share?
|
1)making their own food
2)have a cuticle 3)have a cell wall (cellulose) 4)asexual or sexual reproduction(reproduce with spores and sex cells) |
|
By what process do plants make their own food? What other name can we call them by?
|
photosynthesis; producers
|
|
What is a cuticle?
|
an adaptation and a waxy covering on plants(the stem) that protect the plant from dying out.
|
|
What is a sporophyte?
|
a stage in a plant which produces spores
|
|
What is a gametophyte?
|
a stage in a plant which it produces gametes(sex cells)
|
|
What is chlorophyll?
|
a green pigment found in plants(chloroplast) were it absorbs light energy from the sun
|
|
Explain a plant life cycle
|
1) sporophyte stage
2)gametophyte stage 3)sperm cells firtilize egg cells 4)the firtilized egg becomes a new plant |
|
what are the two ways to classify plants?
|
vascular and nonvascular
|
|
what is vascular and non vascular?
|
vascular: a "tube" in a plants which transports nutrients and water in the plant; they have tissues called vascuar tissues to transport the nutrients
Non-vascular: no "tube" in plant. Uses osmois and diffusion to get is nutrients. |
|
why are non-vascular plants smaller than vascular plants?
|
because if the nonvascular plant were larger, than there will be no way for osmosis or diffusion to get to all the cells
|
|
what are the two divisions of vascular plants?
|
Gymnosperms(non-flowering plants) Angiosperms(flowering plants)
|
|
where do mosses and liverworts live?
|
on rocks, tree bark, or soil
|
|
are all seedless plants vascular?why or why not?
|
no b/c there are plants like mosses and liverworts that are nonvascular
|
|
what do mooses look like?
|
small,green,have rhizoids,lives near ground in groups.
|
|
Each plant has a slender hairlike threds of cells called rhizoids. what are rhizoids? what do mosses use them for?
|
help hold the plant in place (act like roots);
osmosis and diffusion |
|
explain the life cycle of a moss.
|
1)sporophyte stage(releases them into air)
2)spores land on ground and open into a gametophyte 3) sperm cells are carried by water to egg cells. 4)firtilized egg grows into a new plant |
|
how are mosses and liverworts important?
|
1)provide fuel when dried and burned
2)leave a rich soil for new plants to grow 3)provide nesting materials for birds |
|
is spanish moss really a moss? if not then what is it?
|
no; a lichen (a plant that has fungi and algae that grow together)
|
|
underground stem of a fern
|
rhizome
|
|
leaf of a fern
|
frond
|
|
end of a fern frond
|
fiddlehead
|
|
where do ferns grow?
|
almost anywhere.
|
|
explain the life cycle of a fern
|
1)sporophyte stage(realeases spores into air)
2)spores grow into gametophytes 3)gametophyte stage 4)grow into new plants |
|
what are the seed parts?
|
1)seed coat
2)stored food(cotyledons) 3)young plant(sporophyte) |
|
seed plants without flowers or fruit.
|
gymnosperms
|
|
what does gymnosperm mean?
|
naked seed
|
|
what is the life cycle of gymnosperm(pine tree)?
|
1)sporophyte stage
2)male cones open and release pollen 3)pollen sticks to the female cone and firtilizes it 4)female cones open, then it releases seeds |
|
importance?
|
christmas trees, building, and paper
|
|
what are the female parts of a plant?
|
Pistil:sitgma, ovary, ovules, style
|
|
what are the male parts of a plant?
|
Stamen: fliament, anther
|
|
what other parts does a plant have?
|
leaves, petals, roots, stem, sepal
|
|
what is the importance of plants?
|
to atract insects for pollination
