What best describes chlorophyll?

Chlorophyll is a green pigment found in plants and some algae that is responsible for capturing light energy during photosynthesis. This pigment plays a crucial role in the process of converting light energy into chemical energy, which is essential for plant growth and development.

What is the formula for the sugar made by photosynthesis?

The formula for the sugar made by photosynthesis is C6H12O6, which is also known as glucose. During photosynthesis, plants use sunlight, water, and carbon dioxide to produce glucose as a source of energy.

What role dos oxygen play in cellular respiration?

Oxygen is the final electron acceptor in the electron transport chain during cellular respiration. It helps generate a proton gradient that drives ATP synthesis. Oxygen is essential for producing energy in the form of ATP through aerobic respiration.

Where do raw materials for TVs's come from?

Raw materials for TVs come from various sources around the world, including metals like copper, aluminum, and gold; minerals such as quartz and rare earth elements; and plastics derived from oil and natural gas. These materials are mined, processed, and manufactured into components that are then assembled into the final product.

The main photosynthetic area of a leaf is composed of?

The main photosynthetic area of a leaf is composed of cells called mesophyll cells, specifically the palisade and spongy mesophyll cells. These cells contain chloroplasts, which house chlorophyll and are responsible for capturing light energy to drive photosynthesis. The arrangement of these cells maximizes the leaf's surface area exposed to light for efficient photosynthesis.

How do the products of photosynthesis are transported in the plant?

There are veins in the plants.

The sugars and starches travel through veins and osmosis.

The osmosis is the absorption and release through the cell wall. This passes waste and food from one cell to the next.

Which energy system has bi-products of carbon dioxide heat and water?

The aerobic energy system produces carbon dioxide, heat, and water as by-products during the process of metabolizing carbohydrates, fats, and proteins for energy. This system relies on oxygen to efficiently produce ATP, the body's main energy source.

What is the simple version of photosynthesis?

Photosynthesis is the process through which plants and other organisms convert sunlight into energy. During photosynthesis, plants use sunlight, carbon dioxide, and water to produce oxygen and glucose (sugar), which is used as energy for the plant.

Why do green plants photosynthesis?

Green plants photosynthesize to convert carbon dioxide and water into glucose, a form of energy that the plant can use for growth and development. This process requires sunlight and chlorophyll, a green pigment in plants, to capture and convert light energy into chemical energy stored in glucose.

In many plants the rate of photosynthesis when the weather becomes very cold?

In many plants, the rate of photosynthesis decreases when the weather becomes very cold. This is because low temperatures can slow down metabolic processes and enzyme activity, affecting the plant's ability to convert light energy into chemical energy. Additionally, colder weather can lead to frost damage, which can further hinder photosynthetic activity in plants.

What are two main forms of treatment used by psychologists?

Two main forms of treatment used by psychologists are psychotherapy (talk therapy) and medication. Psychotherapy helps individuals explore their thoughts, emotions, and behaviors to address psychological issues. Medication is prescribed by psychiatrists to help manage symptoms of mental health conditions.

How Many Vowels Are In The Word Chlorophyll?

Chlorophyll--There are three vowels in the word chlorophyll.

How does photosynthesis relate to your daily lives?

Photosynthesis is vital for our daily lives as it is the process by which plants, algae, and some bacteria convert sunlight, water, and carbon dioxide into oxygen and glucose. The oxygen released during photosynthesis is essential for us to breathe, while the glucose provides energy for all living organisms. This process is crucial in maintaining the balance of gases in the atmosphere and providing food for the ecosystem.

What is mesnt by destarching a leaf?

Destarching a leaf is a method used in an experiment to prove that there is starch exsisting within the leaf,

Destarching a leaf is also a preparation used before the experiment, to remove all starches within the leaf-NR

What does cellular respiration release in addition to energy?

Cellular respiration releases carbon dioxide and water as byproducts in addition to energy in the form of ATP.

What is given off as a waste product of photosynthesis?

The gas given off as a waste product of photosynthesis is oxygen. Glucose is also made during photosynthesis. These products are made from carbon dioxide and water.

What causes a plan to wilt?

A lack of sun, water, or Carbon Dioxide, because those three are necessary for plants to perform photosynthesis, which makes food for plants. Or if the soil was contaminated with something toxic.

What happens during the carbon fixation step of the Calvin cycle?

Products such as G3P or PGAL are produced in the Calvin cycle in C3, C4, and CAM plants. Carbon fixation helps each plant adapt to the particular environment they live in. C4 plants are those such as sugarcane or grasses. CAM plants are the cactus plants or plants that live in the desert. It also helps with the production of ATP.

What is the purpose of the light dependent reaction and what is it called?

The purpose of the light dependent reaction is to convert light energy into chemical energy in the form of ATP and NADPH. This process, also known as the light reactions or light-dependent photosynthesis, occurs in the thylakoid membranes of chloroplasts.

Respiration is a chemical reaction used to?

Respiration is a chemical reaction used to convert glucose and oxygen into energy in the form of ATP, releasing carbon dioxide and water as byproducts. This process occurs in the cells of living organisms to provide the energy needed for cellular functions and metabolism.

Why is photorespiration bad for a plant?

.

Photorespiration is a process of metabolic pathway that consumes oxygen, releases carbon dioxide, generates no ATP, and decreases photosynthetic output; generally occurs on hot, dry, bright days, when stomata close and the oxygen concentration in the leaf exceeds that of carbon dioxide.

Photorespirationoccurs because Rubisco can utilize O2 as a substrate instead of CO2. It means when stomata partially close on hot day, dry day, CO2 levels drop as CO­2 is consumed in the Calvin cycle. At the same time, O2 levels rise as the light reaction converts light to chemical energy. When the O­­2:CO2 ratio increase, there is not enough CO­2 and rubisco can add O2 to Calvin cycle (RuBP). Therefore, photorespiration consumes O2 and organic fuel and releases CO2 without producing ATP or sugar. Photorespiration reduces net C fixation considerably. Photorespiration also uses ATP & NADPH.

photorespiration is absent in c4 plants but present in c3 plants.It is because c4 plants are present in dry areas.

What is the importance of positive phototropism?

Positive gravitropism (plants grow up) benefits the plant because it has a better root structure. It is an adaption of plants to gravitropism which has a weak root system, however it is beneficial in certain areas for plants to be gravitropes.

How is the leaf structured to carry out photosynthesis?

Plants use photosynthesis, water, and oxygen to create the things they need to survive, however plants cannot do this without its leaves. Especially when the leaves have to adapt to new environments. The leaves go through photosynthesis, which they can only do because they have chloroplasts in them, which convert the sunlight into food. The plants also have cuticles which help the leaves contain the water it absorbs.
