What the meanings of photosynthesis?

It is a Greek word.

It is made up of the words φως (phos, meaning light) and σύνθεσις (synthesis, meaning putting things together in order to make something).

Therefore the meaning is "using light to make something" (energy to grow, etc) Save

Why does the source and sink for translocation in a plant change at different stages in the growth of a plant?

The source and sink for translocation in a plant change at different stages of growth mainly due to the shifting metabolic demands of the plant. During early growth stages, leaves often act as sources supplying nutrients to growing tissues, while later in development, storage organs like roots or tubers may become the primary sink for nutrient accumulation. This dynamic allocation is essential for supporting different growth processes throughout the plant's lifecycle.

Why isn't all of the energy that grass gets from the sunlight passed on to the prairie dogs that eat the grass?

Not all of the energy from the sun captured by the grass is efficiently transferred to the prairie dogs due to energy losses at each trophic level. This is known as the 10% rule, where only about 10% of the energy is passed on to the next trophic level. Energy is lost as heat during metabolism, movement, growth, and other life processes, leading to inefficiencies in energy transfer along the food chain.

Why is it important to respond to an individual reactions during communication?

Responding to an individual's reactions during communication shows that you are actively listening and engaged in the conversation. It helps foster understanding, build rapport, and ensures that the message is being received and interpreted correctly. It also helps create a dialogue and promotes a more productive exchange of ideas.

What were raw materials used by the Maya?

The Maya utilized a variety of raw materials, including limestone for construction and tools, obsidian for sharp blades and weapons, and jade for ornaments and ceremonial items. They also relied on natural resources like cotton and cacao for textiles and trade. Additionally, wood from local forests was used for building and fuel. These materials were integral to their daily life, economy, and cultural practices.

Photosynthesis and cellular respiration are what processes?

Photosynthesis and cellular respiration are fundamental biochemical processes that convert energy in living organisms. Photosynthesis, occurring primarily in plants, algae, and some bacteria, converts sunlight into chemical energy stored in glucose using carbon dioxide and water. In contrast, cellular respiration is the process by which cells break down glucose in the presence of oxygen to release energy, producing carbon dioxide and water as byproducts. Together, these processes form a vital cycle of energy transformation and matter exchange in ecosystems.

Describe the effect of temperature on the rate of photosynthesis of C.caroliniana?

Temperature significantly influences the rate of photosynthesis in C. caroliniana, as it affects enzyme activity involved in the photosynthetic process. Generally, as temperature increases, the rate of photosynthesis rises until it reaches an optimal range, after which it may decline due to enzyme denaturation and increased respiration rates. Optimal temperatures typically range from 20°C to 30°C for many aquatic plants, including C. caroliniana. Extreme temperatures outside this range can lead to reduced photosynthetic efficiency and overall plant health.

What refers to organelles which conduct photosynthesis and closely resemble cyanobacteria.?

The organelles that conduct photosynthesis and closely resemble cyanobacteria are called chloroplasts. These organelles are found in the cells of plants and algae, and they contain chlorophyll, which captures light energy to convert carbon dioxide and water into glucose and oxygen through the process of photosynthesis. Chloroplasts are thought to have originated from an endosymbiotic relationship with ancestral cyanobacteria.

Why do the tunnels not need to be moved to water the plants?

The tunnels do not need to be moved to water the plants because they are designed to allow water to flow through them effectively. This setup enables the moisture to reach the plant roots without disrupting their growth. Additionally, the tunnels can help retain humidity and reduce evaporation, making the watering process more efficient. Ultimately, the design maximizes water usage while minimizing the need for physical adjustments.

Which reaction of photosynthesis is best described by the following statement pgal is produced?

The reaction of photosynthesis best described by the statement "PGAL is produced" refers to the Calvin cycle, also known as the light-independent reactions or dark reactions. During this cycle, carbon dioxide is fixed and converted into glucose and other carbohydrates, with PGAL (phosphoglyceraldehyde) being a key three-carbon intermediate produced. This process occurs in the stroma of chloroplasts and does not directly require light, relying instead on the ATP and NADPH generated during the light-dependent reactions.

What are the products of photosynthesis process?

wht are the product of the process of the photosynthesis

What is primary plants pigment that absorbs sunlight during photosynthesis?

Chlorophyll is the primary pigment that absorbs sunlight during photosynthesis. It is the pigment that is able to absorb the light energy and convert it into chemical energy by loosing electrons easily when struck by light.

What is a reactant photosynthesis?

There are two reactants. They are CO2 and water

What is the relationship between Solar radiation and photosynthesis?

the energy source is sun. Photosynthesis need sun as a energy source.

What the main raw material used for photosynthesis?

Photosynthesis converts CO2 and H2O into sugar and releases oxygen. 6H2O(l) + 6CO2(g) --> C6H12O6(s) + 6O2(g). You see that you are going to have to ask the person posing this question exactly what they mean by "main raw material" because the balanced equation shows that the same number of water and carbon dioxide molecules are participating. If the word "main" means "heaviest" to that person, then, carbon dioxide molecules, weighing 44 g/mol and water molecules weighing 18 g/mol. would mean that the heavier component would be carbon dioxide.

I believe that I would argue that no type of photosynthesis would proceed without light so, the main raw material is light energy.

This is one of those questions for which there is no perfectly correct answer. Getting a strong argument from you is the goal. Be sure you are able to back up your answer.

Why is the H plus ion important in photosynthesis?

they undergo chemiosmosis resulting in the creation of ATP throught ATP Synthase. Also, they are used to make NADPH when combining with the two electrons lost from P700 and with NADP+ left over from the calvin cycle!!!

What is a multicellular plan that engages in photosynthesis?

The majority of plants are multi-celled and they convert light energy into chemical energy (photosynthesis)
