Where is glucose stored after plant plant has made glucose during photosynthesis?

User Avatar

Asked by Wiki User

Glucose produced during photosynthesis is stored in various plant parts such as roots, stems, leaves, fruits, and seeds. It is converted into starch for long-term storage in storage organs like tubers, bulbs, and rhizomes, or utilized immediately for energy production and growth processes within the plant.

What are the requirements of photosynthesis aside from light energy?

User Avatar

Asked by Wiki User

Photosynthesis also requires carbon dioxide, water, and chlorophyll as essential components. Carbon dioxide is taken in from the atmosphere through tiny pores on the plant leaves called stomata, while water is absorbed from the soil through the plant's roots. Chlorophyll is a pigment that absorbs light energy and is necessary for the process to occur.

What plant organelle is used to degrade macromolecules?

User Avatar

Asked by Wiki User

The plant organelle used to degrade macromolecules is the lysosome. Lysosomes contain enzymes that break down larger molecules into smaller components that can be used by the cell for energy or recycling.

What do you call the red coloring pigment of plants?

User Avatar

Asked by Wiki User

The red coloring pigment in plants is called anthocyanin. It is responsible for the red, pink, and purple hues seen in leaves, flowers, and fruits. Anthocyanins also act as antioxidants in plants, providing protection against stress and UV damage.

What is the major product of photosynthesis that keeps plants alive?

User Avatar

Asked by Wiki User

The major product of photosynthesis that keeps plants alive is glucose. Glucose is a type of sugar that plants use as a source of energy to carry out various cellular processes and to support growth and development.

Does photosynthesis occur underwater?

User Avatar

Asked by Wiki User

Yes, photosynthesis can occur underwater in aquatic plants and algae. These organisms use chlorophyll to capture light energy from the sun to convert carbon dioxide and water into glucose and oxygen. This process is essential for the survival of many marine and freshwater ecosystems.

Why is photosynthesis needed for plant growth?

User Avatar

Asked by Wiki User

Photosynthesis is essential for plant growth because it allows plants to convert sunlight into energy in the form of glucose. This energy is used by plants to carry out essential processes such as respiration, growth, and reproduction. Without photosynthesis, plants would not be able to produce the necessary energy to survive and grow.

How much is 6co2 6h2o c6H1206 602?

User Avatar

Asked by Wiki User

The equation represents photosynthesis, where 6 molecules of carbon dioxide and 6 molecules of water undergo a chemical reaction in the presence of light to produce one molecule of glucose (C6H12O6) and 6 molecules of oxygen. This balanced equation is the essential process by which plants and other autotrophs convert light energy into chemical energy stored in glucose.

Why is the food making process in a plant called photosynthesis?

User Avatar

Asked by Wiki User

The food making process in a plant is called photosynthesis because it involves the conversion of sunlight into chemical energy (glucose) that the plant can use for growth and development. This process is facilitated by chlorophyll, a green pigment in plant cells that captures sunlight and drives the chemical reactions necessary for food production.

What raw materials are used to produce tupperware products?

User Avatar

Asked by Wiki User

Tupperware products are typically made from a type of plastic called polypropylene. This material is derived from petroleum, which is a non-renewable resource. Other materials used in the production process may include additives, colorants, and other compounds to enhance the durability and appearance of the products.

What will happen to the produced glucose in photosynthesis?

User Avatar

Asked by Wiki User

The produced glucose in photosynthesis will be used as an energy source by the plant for growth, reproduction, and other metabolic processes. It may also be stored as starch for later use.

What role does the oxygen in cellular respiration play?

User Avatar

Asked by Wiki User

Oxygen serves as the final electron acceptor in the electron transport chain during cellular respiration, allowing for the production of ATP through oxidative phosphorylation. It helps in breaking down glucose molecules to release energy in the form of ATP through a series of metabolic reactions. Oxygen is essential for the efficient production of ATP in aerobic respiration.

What is the polarity of xanthophylls?

User Avatar

Asked by Wiki User

Xanthophylls are polar molecules due to the presence of hydroxyl (-OH) groups in their chemical structure. These hydroxyl groups make xanthophylls soluble in polar solvents like water.

What are the 3 basic events of light independet reactions?

User Avatar

Asked by Wiki User

The three basic events of light-independent reactions (Calvin cycle) are carbon fixation, reduction, and regeneration of RuBP. Carbon fixation involves utilizing CO2 to convert it into a usable form (3-PGA). Reduction involves converting 3-PGA into G3P using ATP and NADPH. Regeneration of RuBP involves converting G3P into RuBP to restart the cycle.

What is the main function of respiration in living organisms?

User Avatar

Asked by Wiki User

The main function of respiration in living organisms is to provide a constant supply of oxygen to cells for cellular respiration, which produces energy in the form of ATP. It also helps remove carbon dioxide, a waste product of cellular respiration.

What molecule is split during the light reaction of photosynthesis?

User Avatar

Asked by Wiki User

A molecule of water is split producing: 2H+ which contributes to the increase in proton gradient, 2 electrons reducing P680+ to P680, and an oxygen atom which later combines with another oxygen atom to form O2.

Why do algae have different photosynthetic pigments from plants?

User Avatar

Asked by Wiki User

Algae have different photosynthetic pigments because they inhabit diverse environments and need to adapt to varying light conditions. The different pigments enable algae to absorb light efficiently across a wider range of wavelengths, allowing them to thrive in environments that may not be suitable for land plants.

What are carbon dioxide water and light energy changed into during photosynthesis?

User Avatar

Asked by Wiki User

During photosynthesis, carbon dioxide, water, and light energy are converted into glucose (sugar) and oxygen. This process takes place in the chloroplasts of plant cells, where the energy from sunlight is used to drive the chemical reactions that produce glucose as a source of energy for the plant.

Where do the carbon atoms come from to produce the certain sugar for photosynthesis?

User Avatar

Asked by Wiki User

The carbon atoms used to produce sugars during photosynthesis primarily come from carbon dioxide in the atmosphere. Plants take in carbon dioxide through small openings in their leaves called stomata, and then use the energy from sunlight to convert the carbon dioxide into sugars through a series of biochemical reactions.

What is the fluid within a chloroplast that contains enzymes involved in the synthesis of carbohydrates during photosynthesis?

User Avatar

Asked by Wiki User

The fluid within a chloroplast that contains enzymes involved in the synthesis of carbohydrates during photosynthesis is called stroma. Stroma is a semi-fluid substance where the Calvin cycle takes place, which is the part of photosynthesis responsible for producing carbohydrates like glucose.

What happens to the rate of photosynthesis when there is no rainfall?

User Avatar

Asked by Wiki User

The rate of photosynthesis may decrease when there is no rainfall because plants need water for the process. Without rainfall, plants may become water-stressed, leading to reduced photosynthetic activity.

How do plants carry out photosynthesis under extremely hot and dry conditions?

User Avatar

Asked by Wiki User

Plants have adapted to hot and dry conditions through mechanisms such as CAM photosynthesis or succulence. In CAM photosynthesis, plants open their stomata at night to minimize water loss during the day. Succulent plants store water in their leaves or stems to withstand drought conditions. This helps plants minimize water loss and continue with photosynthesis even in hot and dry environments.
