why do nonvascular plants tend to be small,growing close to the ground?
|
their food and nutrients are carried directly from cell to cell
|
|
|
how do vascular plants differ from nonvascular plants?
|
vascular plants have vascular tissue in the roots, stems and leaves
|
|
|
vascular tissue
|
tissue that supports plants and carries H2O and food
|
|
|
name two types of vascular tissue
|
Xylem and phloem
|
|
|
what is xylem
|
carries H2O and nutrients from roots to the other parts
|
|
|
what is phloem
|
carries food from leaves to the rest
|
|
|
what is the main difference between taproot and fibrous roots?
|
1: one large strong root that anchors the plant firmly
2: thin and branchy forms a mat below the surface |
|
|
how are these roots systems similar(taproot and fibrous roots)
|
they are both roots that help the plants or tree
|
|
|
what function do the roots perform
|
absorbs water, nutrients and supports the plant
|
|
|
photosynthesis
|
the process of leaves making food
|
|
|
where do plants get the material they need to make food
|
light, energy CO2 and water
|
|
|
what is epidermis? what does it protect?
|
outer layer of cells in a leaf. the leaf from damage
|
|
|
what are stomata? what do they do?
|
tiny holes on the under-side of a leaf. lets CO2 in and oxygen out
|
|
|
what process takes place in the chloroplast of leaf cell?
|
photosynthesis
|
|
|
what is the difference between the sporophyte generation and the gametophyte generation?
|
sporophyte is a spore, a gametophyte is a form of a male and female joining
|
|
|
Spore
|
single cell that can be carried to a new location
|
|
|
how are fern sporophytes and moss sporophytes different? how are they alike?
|
both grow from the gametophytes
moss sporophytes are tall, thin stalks with capsules on top fern sporophytes are tiny, grow flat to the ground |
|
|
what is a seed?
|
a tiny sporophyte inside a protective coat
|
|
|
Why are the seeds of pines considered "naked"?
|
they are protected only by a seed coat
|
|
|
gymnosperm
|
a plant that produces naked seeds
|
|
|
angiosperm
|
a flowering plant that has seeds protected by fruit
|
|
|
how are gymnosperm seeds and angiosperm seeds different? how are they alike?
|
they differ by the gymnosperm makes naked seeds while the angiosperm makes fruit
they are alike because they are both plants and they produce something |
|
|
why are a flower's petals important in reproduction
|
they attract insects that then pollinate the flower
|
|
|
what are the differences between pollen transfer in a pine tree and in many flowering plants?
|
pine pollen is blown by the wind, flowering plants transfer pollen by insects or other animals
|
|
|
germinate
|
to sprout
|
|
|
how do the leaves of an embryo differ from the leaves of a mature plant?
|
leaves of an embryo can't make food like the leaves of a mature plant
|
