autotrophic [ ANS: ] organisms that capture solar energy and
convert it into chemical energy they can use (perform
photosynthesis)
what are the key characteristics of plants? [ ANS: ] - autotrophic
nutrition

- cell wall
- plastids
Guru01 - Stuvia
- vacuole
how do plants get their nutrition? [ ANS: ] 1.) obtain energy and
carbon (through photosynthesis, CO2 and H2O from the
environment)
2.) minerals from substrates such as soil, water, atmospheric
deposition (N, P, K, Ca)
3.) complex organic molecules synthesized by the plant from
carbon skeletons made during photosynthesis (proteins, cellulose,
fats, vitamins)
4.) energy to do work by breaking down carbon skeletons made
during photosynthesis in cellular respiration (ATP/NADH2)

photosynthesis [ ANS: ] Conversion of light energy from the sun into
chemical energy.
minerals [ ANS: ] A solid inorganic substance of natural occurrence
organic molecules [ ANS: ] molecules that contain carbon
carbon skeletons [ ANS: ] provide the basic structures for organic
molecules
cellular respiration [ ANS: ] Process that releases energy by
breaking down glucose and other food molecules in the presence
of oxygen

essential elements [ ANS: ] - essential for a plant's growth,
reproduction, or deficiency if not present
- elements are taken up as simple inorganic ions
Guru01 - Stuvia
- Ca^2+, HPO4^2-, NO3^-, K^+
macronutrients [ ANS: ] - nutrients needed in large amounts
- C, H, O, P, K, N, S, Ca, Mg
micronutrients [ ANS: ] - nutrients needed in very small amounts
- just as essential as macronutrients
- Fe, B, Mn, Zn
limiting nutrients [ ANS: ] - the nutrient whose supply limits
productivity
- N, P, and K are common
- add fertilizer to overcome limitation
N deficient [ ANS: ] - plant small
- leaves chlorotic

- old leaves senesce prematurely
P deficient [ ANS: ] - plant small
- leaves with purple or red tinge
- old leaves senesce prematurely
Fe deficiency [ ANS: ] - leaves pale, clear yellow
- symptoms in young leaves
what are the functions of elements? [ ANS: ] basic building blocks
of molecules, co-factors of enzymes, regulatory, ionic
© 2025 Assignment Expert
other modes of plant nutrition [ ANS: ] - parasitic
- myco-heterotrophic (parasitic on mycorrhizal roots)
Guru01 - Stuvia
- carnivorous
what is the structure of cell walls? [ ANS: ] framework of cellulose
fibers in a matrix of other molecules
cell wall [ ANS: ] A rigid structure that surrounds the cell membrane
and provides support to the cell
cellulose [ ANS: ] - made of glucose units connected by beta 1-4
covalent bonds
- polymers of cellulose group together to form fibrils
- makes up about 1/2 of all organic carbon in the biosphere
compounds in the cell wall matrix [ ANS: ] - hemicellulose
- pectins
- glycoproteins
- enzymes
