what are pneumatophores good for? - ✔✔oxygen uptake
what macronutrient helps with plant growth? - ✔✔nitrogen
deficiency of which mineral causes purplish coloration of the leaves? - ✔✔phosphorus
why can it be difficult for a plant to get access to cations in the soil? - ✔✔clay is often negatively charged
and tightly binds to cations which can make it difficult for the plant to take these ions up
what protein causes a reddish color in plant tissue? - ✔✔leghemoglobin
what is leghemoglobin needed for in the nodules? - ✔✔it's scavenging oxygen that would otherwise
block nitrogen fixation in nodules
infection of legume roots by mycorrhizae leads to module formation and nitrogen fixation- T or F? -
✔✔false
where dos photosynthesis take place? - ✔✔leaves
what is the name of horizontal shoots that grow along the surface? - ✔✔stolons

because roots are not normally photosynthetically active, as a consequence they - ✔✔show a net uptake
of oxygen
what is the difference between apical meristems and lateral meristems - ✔✔apical meristems allow
plant to grow up and lateral meristems allow the plant to grow in width
what are meristems? - ✔✔tissue in most plants containing undifferentiated cells, found in zones of the
plant where growth can take place
where are the stomata located? - ✔✔leaves
phloem sap normally mainly contains - ✔✔water and sugar
what does the majority of the dry weight of a plant body contain and where does it come from? -

movement of h2o through the cell wall happens in the - ✔✔apoplast
contraction of the protoplast of a plant cell as a result of loss of water from the cell - ✔✔plasmolysis
as light intensity increases, the transpiration rate ______. the stomata ______ to allow more carbon
dioxide into the leaf for photosynthesis. - ✔✔increases, open
what does the stomata require to open? - ✔✔potassium ions and guard cells
