33 Facts about Darkness for Kids:
1. Plants don’t do photosynthesis in the dark. Plants perform photosynthesis to make food for themselves using carbon dioxide and water.
2. Plants don’t stop respiration in the dark they respire all the time. Respiration is a process that breaks down glucose to obtain energy for the plants using oxygen.
3. Most of the seeds germinate well in the dark.
4. Plants like cacti and other succulents open their stomata in the dark to take in carbon dioxide for photosynthesis.
5. Heterotroph(Non-Photosynthesizing) plants can grow in complete darkness. They don’t need to do photosynthesis as they don’t make their food.
6. Darkness play a significant role in impacting the Chloroplast distribution, leaf shape and growth patterns in plants.
7. Calvin Cycle in plants takes place in the dark.
8. Nocturnal animals can see in the dark, and they are more active in darkness. Owls, bats, and foxes are an example of Nocturnal animals.
9. Zooplanktons feed at night near the surface of the water bodies. Jellyfish is an example of a Zooplankton.
10. Amphibians like Frogs and Salamanders glow in the dark.
11. Darkness is not against the white background. Instead, whiteness is against the dark background.
12. Everything that looks dark is not always dark. Few objects that look dark are brighter at a frequency that a human eye can not see.
13. There are light-detecting cells in the human eye called rhodopsin. These cells regenerate when adapting to darkness.
14. Dark objects and surfaces absorb heat; because of this, it is said not to wear dark clothes in the summer.
15. Many people and especially kids fear the darkness. They usually do not stress about the dark but the possibilities of dangers in the dark.

22. Heolstor, genip, and sceadu were used instead of the word darkness in old English.
23. It is very difficult to see in the dark. But there is almost always some light. Thus you can see in the dark after some time.

25. If you will mix three primary colours, they will absorb all the visible light, and black colour will form.
26. Mixing three secondary colours will also create black colour as the secondary colours will absorb all the visible light.
27. When vertebrates enter a dark area, the pupil dilates, allowing more light to enter the eye. It improves the night vision of the vertebrates, which is how they can see in the dark.
28. According to physics, an object is dark when it absorbs photons. The absorption of photons makes it appear dim as compared to other things.
29. Paints that are Matte black don’t reflect much visible light. Thus, they look dark. On the other hand, white paints reflect light. Thus they appear bright.
