Which is more important in the growth of plants: heat from the sun, or light from the sun?

Question

please don't make it too complicated...

Answer 1

for photosynthesis and preparation of chlorophyll

Answer 2

Light....Photosynthesisis

Answer 3

Light is more important, I think.

Answer 4

well i will say that light is more important than heat because light will help the plant in preparing its own food and heat will cause the transpiration or the loss of water from the surface of the leaves or the plant body

Answer 5

It would be light....

Photosynthesis is the process by which green plants and certain other

organisms use the energy of light to convert carbon dioxide and water into the

simple sugar glucose. In so doing, photosynthesis provides the basic energy source

for almost all organisms. Oxygen is extremely important to photosynthesis, which

most organisms depend on. Photosynthesis occurs in green plants, seaweeds, algae,

and certain bacteria. Chlorophyll is capable of converting active light energy into a

form (glucose) that is stored in food. The initial phase of the process requires direct

light; water (H2O) is broken down into oxygen (which is released as a gas) and

hydrogen. Photosynthesis, in general, is the reverse of respiration, in which

. . .

A leaf may be viewed as a solar collector crammed full of

photosynthetic cells. The light-independent reaction is cyclic, that is, it begins

with a molecule that must be regenerated at the end of the reaction in order for the

process to continue. The chemical energy required for the light-independent

reaction is supplied by the ATP and NADPH molecules produced in the

ight-dependent reaction. The light-independent reaction

begins in the stroma when these carbon dioxide molecules link to sugar molecules

called ribulose bisphosphate (RuBP) in a process known as carbon fixation.

COMPARSION BETWEEN RESPIRATION AND PHOTOSYNTHESIS

Photosynthesis Respiration

Where? In chlorophyll bearing-cells In all cells

When? In the presence of light All the time

Input Carbon dioxide and water Reduced carbon compounds

and oxygen

Output Reduced carbon compounds, Carbon dioxide and

water

oxygen, and water

Energy Source Light Chemical Bonds

Energy Result Energy stored Energy released

Chemical Reaction Reduction of Carbon compounds Oxidation of carbon

compounds

The equation for photosynthesis is:

6 CO2 + 6H2O --------> C6H12O6 + 6 O2

The chloroplast is the organelle of photosynthesis.

Both are involved in energy metabolism.

Photosynthesis uses most of the energy in sunlight except green wavelengths

(color that's reflected). The light-independent reaction requires the presence of carbon

dioxide molecules, which enter the plant through pores in the leaf, diffuse through

the cell to the chloroplast, and disperse in the stroma. Carbon dioxide cannot pass through the

protective waxy layer covering the leaf (cuticle), but it can enter the leaf through an

opening (stomata). The dark reaction requires ATP which is a

product of light reaction. There are two process of photosynthesis dark

reaction and light reaction.

Both are surrounded by a double membrane with an intermembrane space. In a dark reaction it can occur with or without light.  

Answer 6

i think light...its useful in dark reaction of photosynthesis.
