Photosynthesis

This category is for questions about the chemical process in which autotrophic organisms use sunlight, carbon dioxide and water to make glucose, water and oxygen. This process is vital to life and is of great importance in biology.

How does a leaf of a plant carry out photosynthesis?

leafs have holes in them and they take in the bi-product of humans (CO2) and give us oxygen (o2) they use the Co2 to create glucose molecules (sugar) which makes them producers. Producers are eaten by primary consumers and them by secondary consumers and them by tertiary consumers. even though the tertiary consumers only eat meat (like our old friends the dinosaurs) they still get the greens from plants that you need to survive because they eat the animals that eat the producers (plants). This is what makes the world go round!

Do humans need photosynthesis to survive explain your answer?

No, humans do not need photosynthesis to survive. Photosynthesis is a process by which plants make their own food using sunlight, but humans get their energy from consuming food, not sunlight. Photosynthesis is essential for plants, but not for humans.

How do the potatoes underground contain starch when photosynthesis occurs in the green leaves above?

The product of photosynthesis is a sugar called glucose. Glucose is soluble in water and can therefore be moved round the plant to where it is needed in the plants vascular system. Thus the glucose is taken to the underground stems forming the potatoes and converted into its polymer form (starch) there.

What tissues of the leaf are continuous with those in the stem and root and what functions do they serve?

The vascular tissues (xylem and phloem) in the leaf are continuous with those in the stem and root. They serve the function of transporting water, nutrients, and sugars throughout the plant. Additionally, the epidermal tissue on the leaf's surface is continuous with the epidermal tissues in the stem and root, providing a protective barrier against environmental stresses.

What liquid do plants need for photosynthesis?

Sugars consist of the elements carbon, hydrogen and oxygen. Plants produce sugar from those elements absorbed by their leaves and roots from carbon compounds and water, and with the help of chlorophyll as a catalyst.

Why do plants and other photosynthetic organisms need CO 2 from the atmosphere?

Plants and other photosynthetic organisms use carbon dioxide during photosynthesis to produce sugars and other organic compounds as a source of energy. This process also releases oxygen as a byproduct, which is essential for respiration by plants and other living organisms. The carbon dioxide gas is a key component in the overall carbon cycle of the earth.

Can the color yellow be mixed with other colors to make white?

All colours mixed together will make white, however this is not true for paint, markers, etc.

How is aerobic respiration similar to photosynthesis?

Both aerobic respiration and photosynthesis involve the exchange of gases (oxygen and carbon dioxide). Both processes require the use of electron transport chains to generate ATP. Additionally, both processes involve the creation and utilization of a proton gradient across a membrane to generate energy.

Why are stomata necessary in green plants?

stomata and guard cells are most essential part of a plant because these two structures helps in photosynthesis and is the basis of survival of the plant.the guard cells prevent water loss thus keeping the plant from dehydrating and stomata helps in gas exchange which is important for photosynthesis.

Can plants really go through photosynthesis as long as the spectrum part of the artificial light has wavelengths that the chlorophyll can grab?

Yes, plants can undergo photosynthesis as long as the artificial light source provides wavelengths of light that chlorophyll can absorb. Chlorophyll predominantly absorbs blue and red lights for photosynthesis, so ensuring these wavelengths are present will support plant growth and photosynthesis under artificial light.

How do you reduce the consumption of fresh raw materials?

You can reduce the consumption of fresh raw materials by increasing the efficiency of production processes, recycling and reusing materials, using alternative materials or sourcing materials locally to minimize transportation emissions. Additionally, implementing sustainable practices such as lean manufacturing techniques and designing products with a focus on circular economy principles can help reduce the need for new raw materials.

What role do root hairs play in the process of transpiration?

Root hairs increase the surface area of the roots, allowing for more water absorption from the soil. This water is then transported upward through the plant and eventually transpired through the stomata in the leaves. Root hairs play a crucial role in maintaining the water balance of the plant by facilitating the uptake of water from the soil for transpiration to occur.

Which cell produces glucose during photosynthesis?

In photosynthesis, glucose is produced in the chloroplasts of plant cells. The chloroplasts contain chlorophyll, which captures sunlight energy to convert carbon dioxide and water into glucose and oxygen.

What is the ratio of raw materials to product called?

The ratio of raw materials to product is called the material yield ratio. It measures the efficiency of converting raw materials into finished products.

What energy is radiant energy turned into during photosynthesis?

During photosynthesis, radiant energy is converted into chemical energy in the form of glucose. This process occurs in the chloroplasts of plant cells in the presence of sunlight, water, and carbon dioxide.

Where is photosynthesis trapped in plants?

Photosynthesis is trapped in the chloroplasts of plant cells. Specifically, the process occurs in the thylakoid membranes within the chloroplasts, where chlorophyll absorbs sunlight to drive the conversion of carbon dioxide and water into glucose and oxygen.

What by-products are formed during photosynthesis?

During photosynthesis, by-products like oxygen and water are formed. Oxygen is released into the atmosphere as a waste product of the light-dependent reactions, while water is produced as a result of the splitting of water molecules in the light-dependent reactions.

Why is chlorophyll important in process of photosynthesis?

Chlorophyll is the pigment that captures the radiant energy from the sun. This energy is then used to facilitate photosynthesis.

What is a green colored substance that helps plants use sunlight for photosynthesis?

chlorophyll

The "green substance" is chlorophyll, a green pigment found in the chloroplasts in a leaf. Chlorophyll traps sunlight for photosynthesis- a plant's way of making food for itself using sunlight.

Photosynthesis equation:

sunlight

carbon dioxide + water -------------------> oxygen + glucose

chlorophyll

6CO2 + 6H2O ----------------> 6O2 + C6H12O6

What enters through the stomata light carbon dioxide or water?

Mainly Carbon dioxide enters. Some water can enter,but majority of water leaves through them

How do you perform an exorsism?

Performing an exorcism should only be done by trained clergy members or professionals experienced in this practice. It typically involves prayers, blessings, and the use of sacred items like holy water or relics. It's important to address the situation with caution, sensitivity, and respect for the beliefs and well-being of those involved.

Why are the process of photosynthesis called an air purifying process?

The process of photosynthesis is called air purifing process as during this process plants take in carbon dioxide released from living body and gives out oxygen needed for the living organisms
