Answer:
The high transmittance (low absorption) reading indicates that chlorophyll absorbs very little green light.
The low transmittance (high absorption) reading indicates that chlorophyll absorbs most blue light
Explanation:
- The galvanometer is a device which is used for measuring the electric current.
- In a spectrophotometer the galvanometer is attached to indicated the amount of light that is getting transmitted through a sample.
- If the amount of light that is getting transmitted from the sample is more, the reading of the galvanometer would be higher and if less light is transmitted the reading of the galvanometer would be less.
- Further, the transmittance of a light is inversely proportional to the absorption, that is if the absorption would be low transmittance would be high and vice versa.
- Therefore, when the chlorophyll is exposed to green light, the transmittance is high and this implies that the absorption of green light would be less.
- Similarly, when the chlorophyll is exposed to blue light, a low transmittance indicates a higher absorption of blue light by chlorophyll.
The high-energy electrons produced by the chlorophyll are highly reactive so to move it from the chlorophyll to the other molecules it needs a carrier.
I believe it is nervous tissue
The nervous system includes the brain, spinal cord, and a complex network of neurons. This system is responsible for sending, receiving, and interpreting information from all parts of the body. The nervous system monitors and coordinates internal organ function and responds to changes in the external environment.
• Neurons are the basic unit of the nervous system. All cells of the nervous system are comprised of neurons. Neurons contain nerve processes which are "finger-like" projections that extend from the nerve cell body. The nerve processes consist of axons and dendrites which are able to conduct and transmit signals.
• The brain is the control center of the body. One of these furrows, the medial longitudinal fissure, divides the brain into left and right hemispheres. Covering the brain is a protective layer of connective tissue known as the meninges.
• The spinal cord runs down the center of the protective spinal column extending from the neck to the lower back. Spinal cord nerves transmit information from body organs and external stimuli to the brain and send information from the brain to other areas of the body.
The pigments have a similar
structure of 40 carbon atoms covalently bonded in a chain. Carotenoids contain oxygen atoms in their chemical structure (retinyl functional group) while
xanthophyll does not. This makes carotenoids more non-polar compared to xanthophylls,
hence move farthest in chromatography
paper using a nonpolar mobile phase. Chlorophyll
pigment, on the other hand, has chlorin rings (which are larger) as functional
units hence move slowly in chromatography.
Photosynthetic rates
can be measured by either the amount of
oxygen they consume per particular time period
or the amount of carbon dioxide produced per particular time period. This
is conducted while immersed in water so
as to measure bubble rate formation in case of oxygen production or the change
in water pH in the case of carbon dioxide consumption.
When autumn approaches, the amount
sunlight received by the plant is reduced due to longer night than days. Deciduous trees have adapted by losing
chlorophyll a and b pigments (most important in photosynthesis)
during this time. This leaves a higher amount of the other red and yellow pigments hence making the leaves change from
green to yellow-red.
It is believed that this
is the result of an ancient endosymbiotic
relationship between a protist and a
eukaryotic cell. The protist generates energy
that the eukaryotic can utilize in its growth and reproduction while
the protist is sheltered. This relationship became obligatory symbiosis over
time.
