Biology nerds answer this question.....very challenging.?

Question

Do Elodea plants (or any plants, for that matter) carry out photosynthesis and cellular respiration at the same rate? Why or why not. Give multiple reasons to support your response please.

Answer 1

Probably not. The purpose of photosynthesis is to produce so much food that is not only enough for the plants use, but also there is some left over for other animals too, If plants were to perform photosynthesis at the same rate of cellular respiration, they would only produce enough food that would suffice their own needs.

Answer 2

Definitely NOT !!

Elodea is rather very fast growing ,, if not very , very fast growing ,,

The rate of growth is the rate of surplus ,, no other reasons needed ,, neither would a 2nd reason be valid.

Plant growth is a product , derived from surplus of photosynthesis. After you minus 15 to 25% energy value (sugar value)(true in crop and weed)(annual calculation) for the pathogenic load (overhead) also paid in photosynthetic surplus. So , if your tropical crop has the pathogenic equivalent of 8% sugar value ,, is very acceptable commercially.

But , if you slow down the organism (in plants , say harden off) Pathogenic load will drop simultaneous with the rate photosynthesis. Thereby , the fastest growth rate is not the best. You may be growing pathological mass alongside. (agronomic field priciple). But , Elodeas ,, don't worry about this. I know ,, it was my job to grow this weed for feed.

Sugar (photosynthetic product) has an enthalpic value (chemical heat energy value) ,, that you can match this against a petrol chart (say , petrol equivalent)(.. i.e motor chart) Except that industry uses the fuel oil ,, (diesel) equivalent . Diesel is a very light fuel oil of 25 SG (specific gravity) where factories are built to run ,, say 80 SG and 120 SG (common SMI grade)(small-medium ,, non-specilist tooling).

In pure chemistry the enthalpic value is used to reflect what correctly is the entropic (Prigogine , Hawkings) value ,, to mean the state of matter (thermodynamics) .

** This is like a chemical "Volt potential " ,, that if was left to run out ,, would ultimately mean "no chemical energy left in the universe for Life to move". (** dissipated energy is no good ,, thereby high entropy means a bigger difference against the ambient.) Refer thermodynamic ,, also can ,, refer chaos mathematics. Or , weather calculation.

This is called "heat death" (google that) , , that means "too cold" ,, the guy who picked the name was Prigogine , (1977).

,, here then in industry and real world costing ,, entropy is a rate ,,

Due to this ,, there is now an "s" value in Chemistry , standing for the symbol of entropy. (That means the dissipative potential of chemical energies.) "e" is for enthalpy. For both , direction is irrevesible ,, proof is Prigogine , Ilya.

This is important because Life Sciences , Earth Sciences , Agriculture , Horticulture and Agronomy ,, and environmental sciences is wrong ,, because energy is dissipative and cannot re-cycle , sustain or re-use. (You actually have to put NEW energy into old material ,, called re-claiming the material. ( I am trained in agronomy.) To reclaim materials and bulk is very high energy expenditure ,, and very low thru-put. (,, industrial) so much that re-cycled and politically correct material is more expensive than the virgin material. Due to energy cost.

Biology and chemistry may find difficult to answer your question. Using Mechanical Engineering or Thermodynamic (heat transfer) is better. Because chemistry pay too much attention to elementry details ,, there the entropic convertion is very tedious. (also missing mass , where chemistry tries to trace.)

,, maybe you want to call me a petrol head also. ?

,, IF I had answered a petroleum question out of place ,, they will mark me wrong. BUT , if the global photosynthetic output is not all caught and burnt by respiration ,, it ends up as fossil fuel !!


Petroleum fuels are the photosynthetic surplus from global biomass !! It's solar energy ,, through time. Physics , is important.

Answer 3

Well, no.

First off, they need to produce extra for storage for their seeds so that they can survive the first few weeks of development before growing their first leaf.

Secondly, they need some of these little pockets of energy for active transport for the plant and other stuff, like changing amino acids into proteins into enzymes for photosynthesis.

Thirdly, they'll need it for their flowers (in flowering plants) as nectar to attract agents of pollination so that they can have a chance of sexual reproduction don't they?

Hope I'm right.

Answer 4

No, if you spend more energy than you have/produce you'll die.
