In what organelle do light reactions occur in plants?
Light reactions in plants occur in the thylakoid membrane of the chloroplasts. This process involves capturing light energy and converting it into chemical energy in the form of ATP and NADPH, which are used in the Calvin cycle to produce sugars.
True or false The light reactions of photosynthesis can occur only under light conditions and the dark reactions can occur only during the dark hours?
False. The light reactions of photosynthesis require light to convert solar energy into chemical energy, while the dark reactions (Calvin cycle) do not directly rely on light and can occur in both light and dark conditions. However, the dark reactions are indirectly dependent on the products of the light reactions.
Do plants grow faster in dark or sun?
Plants require light for photosynthesis, so it is impossible for plants to increase in dry biomass without any light. Some plants do not require high levels of light for growth, because they are adapted to low light conditions (such as jungle and forest plants). Plants left in the dark will grow taller than plants in lighted conditions over a short period of time, but they will also be yellower and more spindly (etiolation). The increased height is a response to low light levels - the plant is trying to grow over anything that may be blocking the light, and will grow towards any source of light. As mentioned in the discussion page of this question this response is controlled by auxins in the plant growth points. For very short periods of time the plant will appear to be going faster than a control plant in normal light intensities - however, this is because the stem is normally thinner so the amount of biomass produced is roughly the same. In addition the plant has to make use of stored energy reserves as it is not able to photosynthesis. Etiolation is a form of self-protection mechanism, the plant expends energy and reserves looking for a source of light that can ensure its continued survival.
When you step out of a bright light into the dark what is the process called that happens to your eyes?
The process is called dark adaptation. It occurs when your photoreceptors in the retina become more sensitive to light in low-light environments after being exposed to bright light.
Are mosquitoes more attracted to light or dark colors?
Mosquitoes are more attracted to dark colors than light colors.
Does food mold faster in the light or dark?
in dark, warm, moist places
Does mold grow faster in the light or dark?
Mold can grow better in the light because when fruits get into the dark they can spoil faster and get soft/ugly
Does a banana rot faster in light or dark?
It rots faster in the light.
Does a banana rot faster in the light or in the dark?
It rots faster in the light.
Do light bruises heal faster or do dark bruises heal faster?
Light Bruises
Which cooks faster-chicken light or dark?
Chicken dark or light cooks the fasters
Do kangaroos live in dark or light places?
Kangaroos live in light places.
Does a pear rot faster in the dark or light?
yes
Does watery bread grow mold faster in dark places?
Yes
Do beans grow in the dark?
Yes. They actually grow faster in the dark than in the light.
Does sunlight heat light sand or dark sand up faster?
As with just about everything, the sun will heat dark-coloured sand faster than light coloured sand. Dark colours absorb heat better than light colours.
Does ice melt faster in light or dark?
Ice melts faster in dark environments because dark surfaces absorb more heat than light surfaces, which accelerates the melting process. Light surfaces, on the other hand, reflect more heat and help maintain a cooler temperature.
