Leaf Pigments and Light

Pigments of Photosynthesis

No. Photosynthetic pigments do not strongly absorb UV light.

No. Photosynthetic pigments do not store energy.

No. Water is hydrolyzed by an enzyme in photosystem II, not by the pigment molecules.

Consider the energy source for photosynthesis.

The most important role of pigments in photosynthesis is to __________.

Which of the following pigments does NOT absorb yellow/orange light (650-750nm)?a) Chlorophyll a.b) Carotenoids.c) Chlorophyll b.d) &nbsp;Both a &amp; c.

No. Plants are green because they are not absorbing the green light.

No. Plant pigments are more selective than this.

No. Plants absorb light in the visible range.

No. Carotenoids are accessory pigments, absorbing light in only one area of the spectrum.

Consider the action spectrum of photosynthesis.

What is the range of wavelengths of light that are absorbed by the pigments in the thylakoid membranes?

No. Both grana and cristae play a role in energy transformation.

No. Both contain both proteins and lipids.

No. Only one of the listed characteristics is correct.

Consider the functions of chloroplasts and mitochondria.

You could distinguish a thylakoid membrane from an inner mitochondrial membrane because the thylakoid membrane would __________.

3 Major Classes of Pigments in Photosynthesis

Carotenoids, chlorophyll b and chlorophyll a.

Examples of accessory pigments for photosynthesis are:a) Chlorophyll b and carotenoids.b) Chlorophyll a and chlorophyll b.c) Chlorophyll a and carotenoids.d) Carotenoids, chlorophyll b and chlorophyll a.

Animation: Light Energy and Pigments

Why is chlorophyll green?
a. It absorbs all wavelengths in the visible spectrum.
b. It absorbs wavelengths only in the red portions of the spectrum (680–700 nm).
c. It absorbs wavelengths only in the blue part of the visible spectrum (450–480 nm).
d. It absorbs wavelengths in only the blue and red parts of the visible spectrum.

Introduction to Photosystems

Chloroplasts, Pigments And Photosystems in Photosynthesis

No. In fact, if a photosystem is present, just the opposite will happen&mdash;the pigments become oxidized.

No. The absorbed light increases the potential energy of the pigments.

No. The Calvin cycle is a separate, non-light-dependent pathway.

No. Photons come from the sun, not from a chloroplast.

When chloroplast pigments absorb light, __________.

Separation of Pigments from the Extract of Spinach Leaves by Paper Chromatography - MeitY OLabs

How is energy transferred among antenna pigment molecules?
a. by heat
b. by redox reactions
c. by fluorescence
d. by resonance

Absorption Spectrum of Photosynthesis

Why is the chlorophyll in chloroplasts less likely to produce fluorescence compared to extracted chlorophyll molecules?
