Four of the five answers listed below are part of the light-independent reactions?
Calvin cycle (correct) Glycolysis Krebs cycle Light harvesting Electron transport chain The light-independent reactions, or Calvin cycle, are responsible for fixing carbon dioxide into sugars. Glycolysis, Krebs cycle, and electron transport chain are part of the light-dependent reactions, which involve capturing and converting light energy into chemical energy. Light harvesting is also part of the light-dependent reactions, where light is absorbed by pigments to initiate the process.
Four forms of energy that might be absorbed or released during a chemical reaction?
endothermal energy (absorbs heat)exothermic energy (releases heat)light energy e.g. burning magnesium produces a bright whitechemical energyNOTE: Kinetic energy is NOT a form of energy from chemical reactions. It is a common mistake to think so e.g. when sodium (Na) is placed on a piece of filter paper on a container of water, the reason it moves is from the bubbles of gas (hydrogen, H) propelling it. It is not moving by itself.
What is the photosynthetic pigment in plants?
There are a four main photosynthetic pigments in green plants. Chlorophyll a, chlorophyll b, carotene and xanthophyll. These all absorb different areas of the spectrum therefore allowing the plant maximum absorption of light from the sun, and hence photosynthesise effectively.
What organelle is responsible for the reds oranges and yellows in autumn leaves?
Four pigments in leaves, chlorophyll, carotenoids, anthocyanins and tannins are responsible for leaf color changes. Cartenoids are responsible for the yellow and orange pigments of leaves. They reside in the chloroplasts and assist chlorophyll in the photosynthesis process. As chlorophyll diminishes, the color changes. Anthocyanins cause leaves to turn to red. It is formed in the cell sap that resides inside the vacuole.
What four things does a flower need for photosynthesis?
A flower needs sunlight, water, carbon dioxide, and chlorophyll to carry out photosynthesis. Sunlight provides energy for the process, water is used in the reaction, carbon dioxide is absorbed from the air, and chlorophyll is the pigment that captures the light energy.
What are four examples of plant pigments?
orange carotenes and yellow xanthophylls, absorb different wavelengths of light and pass that energy on to chlorophyll molecules. The carotenoids are pigments, including carotenes

What are four possible things that can happen when light travels in a straight path until it hits an object?
Reflection: Light bounces off the surface of the object. Absorption: Light energy is absorbed by the object. Transmission: Light passes through the object without being absorbed or reflected. Refraction: Light changes direction as it passes through the object, due to a change in the medium's optical density.
What are four ways that light waves can behave when they strike an object?
Light waves can be absorbed by the object, reflected off the object's surface, transmitted through the object, or refracted as they pass through the object.
What are four ways that light interacts with matter?
Light can be absorbed by matter, causing electrons to move to higher energy levels. It can be scattered in all directions, such as when it hits gas molecules in the atmosphere. Light can also be transmitted through matter, allowing it to pass through materials like glass or water. Finally, light can be reflected off surfaces, changing its direction without being absorbed.
What are the four main things that can happen when light hits an object?
When light hits an object, it can be absorbed (taken in by the object), reflected (bounced off the object), transmitted (pass through the object), or refracted (bent as it passes through the object).
What is the four natural sources of pigments?
The four natural sources of pigments are plants (e.g., fruits and vegetables), animals (e.g., insects), minerals (e.g., iron oxide), and microorganisms (e.g., bacteria and fungi). These sources are used to extract pigments for various applications, such as in food coloring, cosmetics, and art.
What four factors have an affect on absorbance of light?
Light penetration refers to the depth that light can penetrate into a material. On water surfaces, the factors that can affect light penetration are the angle of the sun, density, wavelength and the type of water surface.
What are the four reasons why energy is not uniformly absorbed on earth?

what are four components of paint?
Four key components of paint are pigments, binders, solvents, and additives. Pigments provide color and opacity, while binders hold the pigments together and adhere them to the surface. Solvents, which can be water or oil-based, adjust the paint's viscosity and facilitate application. Additives enhance specific properties, such as drying time, durability, and resistance to mold or mildew.
What four things are nessessary in photosynthesis?
The four necessary things in photosynthesis are sunlight, water, carbon dioxide, and chlorophyll. Sunlight provides the energy needed for the process, water is used in the light-dependent reactions, carbon dioxide is absorbed from the atmosphere, and chlorophyll is the pigment that captures light energy.
