the answer is chlorrophyll
Chlorophyll is a chemical in the chloroplasts of a plant cell that enables the plant to make it's own food in the leaves of the plant. It also gives the plant it's green color.
Chlorophyll
because they reflect green light
Water (H2O) is taken by the roots of plants and it comes out through the leaves during transpiration.
That is a physical change.
Leaves are the main component of a plant that takes light energy, converts it into chemical energy (sugar), and delivers the sugar throughout the plant through "veins" called phloem.
Yes they do, all tobacco products have nicotine in them. Nicotine is a chemical that is in the leaves of a tobacco plant, much like THC in the leaves and buds of a hemp plant.
The plant transforms electromagnetic energy (light) into chemical energy in photosynthesis.
By chemical analysis of the leaf extract one can determine the plant constituents of mahogany.

the pesticides in the plant wouldn't be excreted out of the plant although it had rained afterwards.. this is because, the chemical substances in the pesticide was diffused via the roots of the plant since the chemical substances are more concentrated than the fluid in the plant... Thus, the chemical substance are hypertonic to the plant roots... the substances from the roots will be transported through the xylem tissue of the plant until it reaches the leaves... so the pesticide is contained in the plant... the insect eats the plant and will eventually die afterwards... therefore, the rain couldn't easily wash out the pesticide.... :)
Any part of the plant that is green will have cells that contain chloroplasts which are responsible for capturing light and converting it to chemical energy.
That is a physical change.
Chloroplasts are the structures used for photosynthesis. Chloroplasts are organelles found in plant cells and algae (plantlike protists). Chloroplasts contain a green pigment called chlorophyll, which do the chemical processes of photosynthesis. Chlorophyll is what gives leaves their green color.
