Photosynthesis in plants is a process that does not require energy obtained from pre-formed organic molecules. Instead, plants use light energy to convert carbon dioxide and water into glucose and oxygen. This process is vital for the plant's growth and survival.

Why water has a higher boiling point than an organic molecule with same molecular weight?
Water has a higher boiling point than organic molecules of similar molecular weight due to hydrogen bonding between water molecules. Hydrogen bonds are stronger intermolecular forces compared to the van der Waals forces found in most organic molecules. These stronger hydrogen bonds require more energy to break, resulting in a higher boiling point for water.
Does peaty soil have the ability to hold water?
Yes, peaty soil has the ability to hold a significant amount of water due to its high organic matter content. The organic material in peat acts like a sponge, absorbing and retaining water, making it beneficial for plants that require consistent moisture.
There are molecules of air at high elevation's so air pressure is less?
Yes, that's correct. As altitude increases, there are fewer air molecules present in the atmosphere, resulting in lower air pressure. This is why individuals may experience difficulties breathing or require acclimatization at higher elevations.
Are minerals living?
No, minerals are not living things. They are naturally occurring inorganic substances with a specific chemical composition and structure. Living organisms require organic compounds for growth and reproduction, which minerals do not possess.
Does a hydrocarbon with large molecules have a higher boiling point that one with small molecules?
Yes, generally speaking, hydrocarbons with larger molecules have higher boiling points compared to those with smaller molecules. This is because larger molecules have stronger intermolecular forces, such as London dispersion forces, which require more energy to overcome in order to change from a liquid to a gas state.
Compared with the rate of an inorganic reaction the rate of an organic reaction is usually?
Slower. Organic reactions typically involve breaking and making covalent bonds in complex organic molecules, which can be slower than inorganic reactions that involve simpler molecules with weaker bonds. Organic reactions often require specific conditions and catalysts to proceed efficiently.
What type of organic molecules require the action of emulsifiers to be digested?
Lipids: fats from animals & oils from plants. Oils are liquid at room temperature.
What are similarities between autotrophs and Heterotrophs?
Similarities: 1. both have life 2.need air, water and sunlight for survival 3. require organic molecules(food) for metabolism
Spontaneous formation of organic molecules does not happen today because they are?
not thermodynamically favored under current atmospheric conditions and require specific energy sources or catalysts to form. The presence of oxygen in our atmosphere also prevents the accumulation of organic molecules by quickly breaking them down.
What about combustion reaction makes them different from either synthesis or decomposition reaction?
The short answer is combustion reactions are a subset of synthesis reactions that require one of the reactants to be oxygen. Common combustion of organic molecules results in the formation of CO2 . However, it is not required that combustion be limited to organic molecules. They are different from decomposition reactions in the same way synthesis is the opposite of decomposition.
Why water has a higher boiling point than an organic molecule with same molecular weight?
Water has a higher boiling point than organic molecules of similar molecular weight due to hydrogen bonding between water molecules. Hydrogen bonds are stronger intermolecular forces compared to the van der Waals forces found in most organic molecules. These stronger hydrogen bonds require more energy to break, resulting in a higher boiling point for water.
Do all fungi require organic material for growth?
Yes, fungi are heterotrophs and require organic material for growth. They obtain nutrients by decomposing organic matter or by forming symbiotic relationships with other organisms.
What are photoheterotrophs?
Photoheterotrophs are organisms that use light as an energy source, but require organic compounds from their environment as a carbon source. They are unable to fix carbon dioxide into organic molecules through photosynthesis like photoautotrophs. Examples of photoheterotrophs include some bacteria and certain protists.
What organic molecule stays in the stomach the longest?
Proteins tend to stay in the stomach the longest compared to other organic molecules because they require more time to break down due to their complex structure. This allows proteins to be slowly digested and absorbed in the stomach over a longer period of time.
Does a medium need molecules?
Mediums are made of molecules. Actually, we're all made of molecules whether we are mediums or not. We require molecules to breath, to drink, to eat, and to exist. Psychic ability has no bearing on one's need for molecules.
Microorganisms require large quantities of this nutrient for use in cell structure and metabolism?
Microorganisms require large quantities of carbon for use in cell structure and metabolism. Carbon provides the backbone for organic molecules needed for growth and energy production.
What are pathways that require energy to combine molecules together called?
Pathways that require energy to combine molecules together are called anabolic pathways. These pathways involve the synthesis of complex molecules from simpler building blocks, requiring energy input in the form of ATP.
