Why photosynthesis do not occur at night?

User Avatar

Asked by Wiki User

'Photosynthesis' requires the energy of Ultraviolet (UV) light, which is only present in daylight/sunlight.

When it is night there is no sunlight, hence no UV light, hence photosynthesis does not occur.

The word photosynthesis' can be separated into 'photo' and 'synthesis'

'Photo' means 'light' and 'synthesis' means 'putting together'. So overall the word means 'putting together by light'.

Is mental illness curable?

User Avatar

Asked by Sammy Beahan

Can mental illness be curable? I would say yes. I believe in the environment being the main role in how a person is. All persons have eccentric or idiosyncratic things about them, but not everyone is labeled. I do think that "all roads lead to Rome." Just because there are or were problems in one's life, each moment brings you forward to the future. I believe each person has more potential than what you see. I don't like labeling persons with such and such an illness.

What are the effects of fruits in the cooked gelatin?

User Avatar

Asked by Wiki User

When fruits are added to cooked gelatin, several effects can occur:

  1. **Texture:** Fruits can add texture to the gelatin, providing a contrast to the smooth gelatin base. Depending on the fruit used and how it's prepared, it can be soft, firm, or crunchy.

  2. **Flavor:** Fruits can impart their flavor to the gelatin, enhancing its taste. The sweetness and tartness of fruits can also balance the sweetness of the gelatin.

  3. **Appearance:** Fruits can add visual appeal to the gelatin, making it more colorful and interesting. They can be used as garnishes or mixed into the gelatin for a decorative effect.

  4. **Nutritional Value:** Fruits are rich in vitamins, minerals, and antioxidants. Adding fruits to gelatin can increase its nutritional value, providing additional health benefits.

  5. **Setting Time:** Some fruits contain enzymes that can affect the setting of gelatin. For example, pineapple and kiwi contain enzymes that can break down gelatin and prevent it from setting properly unless the fruits are cooked or canned.

Overall, adding fruits to cooked gelatin can enhance its texture, flavor, appearance, and nutritional value, but it's important to consider the type of fruit and its preparation to ensure that it sets properly.
