what is the difference between light dependent and light independent?

In the light-dependent reactions, energy from sunlight is absorbed by chlorophyll and that energy is converted into stored chemical energy. In the light-independent reactions, the chemical energy harvested during the light-dependent reactions drives the assembly of sugar molecules from carbon dioxide.

Difference between Luminous and Non-Luminous Objects Objects that can emit light energy by themselves are known as luminous objects. Objects that cannot emit light energy by themselves are known as non-luminous objects. These objects can cause the sensation of light. These objects do not cause the sensation of light.

Your independent variable is definitely the solvent used. In the case of your first hypothesis though, I would say that the dependent variable is more how well the dyes separate. Rf value is one measure of this, so you can definitely use it, but it may also be how many different colors you can count on your strip.

You need to know the difference between hard light and soft light. Hard light makes distinct, hard-edged shadows. Soft light makes shadows that are barely visible. ... When the sun is straight overhead the light is harsh and unflattering—think overhead lightbulb.

Light transmission capacity varies from object to object. Transparent objects allow all the light to pass through them, translucent ones allow partial light to pass, whereas opaque ones allow no light to pass through.

In practice, a sustained interference pattern cannot be obtained by using two independent sources of light. It is because of the following reasons: Two independent sources of light can't emit waves continuously. The waves emitted by two independent sources of light do not have same phase or a constant phase difference.

The two are linked together and controlled by enzymes. The light-dependent reaction is a photochemical reaction taking place in the thylakoid membranes of chloroplasts, where light energy is transformed into adenosine triphosphate (ATP) and nicotinamide adenine dinucleotide phosphate (NADPH).

The amount that the plants grow depends on the amount of sun they get. The independent variable is what you change, and the dependent variable is what happens because of the change. The only way to get reliable results from this experiment is to make sure that all the other variables stay the same, or are controlled.

There are major functional differences between the rods and cones. Rods are extremely sensitive, and can be triggered by a single photon. At very low light levels, visual experience is based solely on the rod signal. Cones require significantly brighter light (that is, a larger number of photons) to produce a signal.

The difference between year and light year is that one is a unit of time and the other is a unit of distance. A year is a unit of time describing the time it takes for the earth to orbit the sun. A light year is the distance light travels in a year which works out to roughly 5.8 trillion miles.

The light-dependent reactions convert light energy into chemical energy, producing ATP and NADPH.

What is the difference between a density-dependent limiting factor and density-independent limiting factor? Density-dependent are affected by number of individuals in a given area (ex. food, disease, predation, competition); Density-independent are factors in the environment that limit the growth of a population (ex.

4. The light-dependent reactions convert light energy into chemical energy, producing ATP and NADPH. 5. The light-dependent reactions can be summarized as follows: 12 H2O + 12 NADP+ + 18 ADP + 18 Pi + light and chlorophyll yields 6 O2 + 12 NADPH + 18 ATP.

Ultraviolet light (UV) is more energetic, but invisible to human eyes. Infrared light is also invisible, but if it is strong enough our skin detects it as heat. It is the energy in each photon of light that causes a chemical change to the photographic detectors that are coated on the film.

Variables. Independent variable - the light intensity (how close the light is). Dependant variable - the number of oxygen bubbles given off (the rate of photosynthesis). Controlled variables - the size of the pondweed, the volume of water used and its temperature.

1 Answer. Cyclic photo-phosphorylation in photosynthesis light dependent reaction leads to the formation of ATP and NADPH, and the electrons go from water to PSII to PSI and eventually to NADPH. In non-cyclic photo-phosphorylation only some ATP is produced and the electrons go from PSII to PSI and back again.
