To make it look more appealing to the eye so as to want to eat it more. EX: You probably wouldn't want to eat a mold looking substance even if it tasted like heaven?
Thats my best guess.
Chlorophyll
Its called chlorophyll which is in the plant's chloroplasts.
No, food coloring will not change the color of potted plants. Plants get their color from pigments produced in their cells, and adding food coloring to the soil will not affect the plant's natural coloration.
Carnations, daisies, and white roses are popular choices for changing color with food coloring because they have a high water uptake capacity. Placing the flowers in water mixed with food coloring allows the petals to absorb the color and change over time.
The green coloring of leaves is due to a pigment called chlorophyll. Chlorophyll is essential for photosynthesis, the process by which plants make food using sunlight.
No.
photosynthesis
they use this thin called xylem
Unless the food coloring has some active ingredient, it will not affect the salt water chemically. In the environment, adding excessive food coloring to water may reduce the amount of light available to plants living in the water. Otherwise the coloring itself is innocuous.
Chlorophyll
yes it does! It uses something called capilarry action
Food coloring can be derived from both renewable and non-renewable sources. Natural food colorings, which come from plants, fruits, and vegetables, are considered renewable as they can be sustainably sourced and replenished. In contrast, synthetic food colorings, often made from petrochemicals, are non-renewable. Therefore, the renewability of food coloring depends on its source.
no there is not DNA in food coloring
You take food coloring and add it to the plants water it will change the color
Its called chlorophyll which is in the plant's chloroplasts.
chlorophyll is the green coloring plants use in photosynthesis
food coloring doesnt stick to food it obsorbes into food
