BIO 2 NUTRIOTION IN PLANTS Flashcards
any substance required for the growth and maintenance of an
organism.
Nutrients
Organisms that produces
its own food
commonly referred to as
“producers”
use photosynthesis or
chemosynthesis
Autotrophs
organisms that carry out
photosynthesis
makes organic compounds
using energy from the sun
PhotoAutotrophs
organisms that carry out
chemosynthesis
makes organic compounds
using energy from the
oxidation of chemicals
ChemoAutotrophs
Consumers
Organisms that cannot make their own food They obtain energy
from other organisms
heterotrophs
-“Insect-eating plants or
Carnivorous plants”
-Derive most of their nutrition
from the insects, that they
trap and consume
These plants grow on soils
that lacks minerals
Insectivorous nutrition
Derive nutrition from dead
and decaying plants and
animals.
Obtains food by absorbing
dissolved organic material
Saprophytic nutrition
Depends on another
organism for survival
Mutualism - Both species
are mutually benefited
Parasitic - One organism is
benefitted at the expense
of the other
Symbiotic nutrition
C, H, O, N, K,
Ca, Mg, P, S
Macro nutrients
Cl, Fe, B, Mn, Zn, Co,
Mo, Cu, Ni, Si, Na
Micronutrients
water moves through the
spaces between the cells and
in the cells walls themselves (water moves freely through WITHOUT ENTERING the cell)
Apoplast
water passes from cytoplasm to cytoplasm through plasmodesmata(water moves INSIDE the cell)
Symplast
water moves through each cell, crossing the cell membrane every time it enters or exits a cell.
Transmembrane
Tiny, finger-like projections from epidermal cells of roots.
Increase surface area for water and mineral absorption.
Root hairs
swellings on the roots of leguminous plants (like beans, peas, and peanuts) house nitrogen-
fixing bacteria.
root nodules
Mutualistic relationship between plant roots and fungi.
The plants provide nutrients to the
fungus and, in return, the fungus provides water and certain nutrients.
Mycorrhizae
