habitat
An important example of interaction between fungi and certain other organisms is mycorrhizae, in which the fungal partners __________.
provide carbohydrates to the plant partner
sicken herbivores that attempt to feed on plants
help plants take up nutrients and water
control soil nematodes
cause the decay of cellulose and lignin
help plants take up nutrients and water
Most bryophytes, such as mosses, differ from all other plants in that they __________.
produce spores
do not produce flowers
have cones but no seed
slack true leaves and roots
have flagellated sperm
lack true leaves and roots
explain plant growth
(phloem, xylem sugar)
1) leaf cells produce sugar through photosynthesis
2) actively transported into the phloem near the sour
3) becomes a passive process as water diffuses into sugar conducting phloem
4) volume increases, creates positive hydrostatic pressure that builds up in phloem and pushes water and solutes down the plant
5) sugar moves to roots for energy
came from saltwater
chlorophytes
generations and vascular tissue
gametophyte and sporophytes, non-vascular
what is primary vs secondary growth
primary is up, secondary is out
Which tissue is responsible for plant growth?
