What is the first most immediate thing that happens when light strikes a chlorophyll molecule?
When light strikes a chlorophyll molecule, electrons in the chloroplast get excited.
What happens to sunlight that strikes a leaf but is not trapped by chlorophyll?
Sunlight that is not trapped by chlorophyll in the leaf is either reflected, transmitted through the leaf, or absorbed as heat. Only a small portion of sunlight wavelengths are absorbed and utilized by chlorophyll for photosynthesis.
Sunlight energy is trapped by chlorophyll located in the?
Sunlight energy is trapped by chlorophyll located in the chloroplasts of plant cells. This energy is used in the process of photosynthesis to convert carbon dioxide and water into glucose, a form of chemical energy that plants can use for growth and metabolism.
What is the role of chlorophyll in light dependent reaction?
Chlorophyll is a pigment that absorbs light energy in the light-dependent reactions of photosynthesis. It is responsible for capturing sunlight and transferring that energy to other molecules in the photosystem, initiating the conversion of light energy into chemical energy in the form of ATP and NADPH. This process ultimately leads to the production of oxygen as a byproduct.
Summarize how photosynthetic organisms capture the energy in sunlight?
The light-dependent portion of photosynthesis is carried out by two consecutive photosystems (photosystem I and photosystem II) in the thylakoid membrane of the chloroplasts. The photosystems are driven by the excited chlorophyll molecules.To begin photosynthesis, the chlorophyll molecule in photosystem II is excited by sunlight and the energy produced helps to break down a water molecule (H2O) into ½O2 (with electrons removed) and 2H+. The removed electrons are excited by the light energy. When the electrons prepare to come to their rest state, they go through an oxidative phosphorylation process and produces an ATP molecule.As the electrons are coming to a resting state, they are excited again in photosystem I and raised to a even higher energy state. The excited electrons are then used to produce NADP+ + H+. The highly energetic NADPH molecule is then fed into the Calvin Cycle to conduct carbon fixation.

What is the first most immediate thing that happens when light strikes chlorophyl molecule?
When light strikes a chlorophyll molecule, electrons in the chloroplast get excited.
What happens when light strikes green light pigments?
The green pigment found in photosynthetic plants is called chlorophyll; it is responsible for converting sunlight.
Describe what happens when sunlight strikes chlorophyll?
When sunlight strikes chlorophyll, the pigment absorbs the light energy and drives a series of chemical reactions known as photosynthesis. This process converts carbon dioxide and water into glucose and oxygen, which is the primary way plants produce food and oxygen.
When sunlight strikes chlorophyll the cell can make food for the?
When sunlight strikes chlorophyll, the plant cell undergoes photosynthesis to convert sunlight, carbon dioxide, and water into glucose (sugar) and oxygen. This process allows the plant to produce its own food for energy and growth.
What happens to sunlight that strikes a leaf but is not trapped by chlorophyll?
Sunlight that is not trapped by chlorophyll in the leaf is either reflected, transmitted through the leaf, or absorbed as heat. Only a small portion of sunlight wavelengths are absorbed and utilized by chlorophyll for photosynthesis.
What happens when sunlight strikes a plant's leaves?
When sunlight strikes a plant's leaves, it is absorbed by chlorophyll, the green pigment in the leaves. This energy drives the process of photosynthesis, where carbon dioxide and water are converted into glucose and oxygen. The glucose serves as an energy source for the plant, while the oxygen is released into the atmosphere as a byproduct. This process is essential for plant growth and contributes to the overall ecosystem by providing energy for other organisms.
Electrons within certain chlorophyll molecules are elevated to a higher energy level when sunlight strikes a?
This elevation of electrons to a higher energy level in chlorophyll molecules is called excitation. It occurs during the process of photosynthesis, where sunlight is absorbed by chlorophyll molecules in plant cells to convert light energy into chemical energy. The excited electrons help drive the production of energy-rich molecules like ATP and NADPH, which are used to fuel the plant's growth and metabolism.
What layer does sunlight strikes first?
The Earth's layer that sunlight strikes first is the ozone layer.
What happens to sun light that strikes a leaf but is not trap by the chlorophyll?
It is either transmitted or reflected. Often, different portions of the light do both.
What is produced in the upper atmosphere when sunlight strikes oxygen atoms and causes them to temporarily combine?
Ozone (O3) is produced when sunlight strikes oxygen atoms in the upper atmosphere, causing them to temporarily combine into the ozone molecule. This process is essential for filtering out harmful UV radiation from the sun.
What happens when sunlight strikes earth?
When sunlight strikes the Earth, it provides energy for photosynthesis in plants, warms the planet's surface, and drives the Earth's weather patterns and climate. Sunlight also stimulates the production of vitamin D in human skin and provides illumination for various organisms to carry out their daily activities.
