Under What Conditions Do Photosynthesis And Cellular Respiration Occur In Most Plants??

Under what conditions do photosynthesis and cellular respiration occur in most plants? Photosynthesis occurs only in the light, and cellular respiration occurs in both the dark and the light.

Under what conditions does cellular respiration occur in plants?

In the natural environment, plants produce their own food to survive. As with photosynthesis, plants get oxygen from the air through the stomata. Respiration takes place in the mitochondria of the cell in the presence of oxygen, which is called “aerobic respiration”.

Under what conditions do photosynthesis?

To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. for photosynthesis. Carbon dioxide enters through tiny holes in a plant’s leaves, flowers, branches, stems, and roots. Plants also require water to make their food.

What conditions does cellular respiration occur?

Cellular respiration always begins with glycolysis, which can occur either in the absence or presence of oxygen. Cellular respiration that proceeds in the absence of oxygen is anaerobic respiration. Cellular respiration that proceeds in the presence of oxygen is aerobic respiration.

Does cellular respiration and photosynthesis occur in plants?

Plants carry out both photosynthesis and cellular respiration. They make their own food, and then break down those glucose molecules later, generating ATP to power their cellular processes. Fun fact!

Does photosynthesis only occur in plants?

Photosynthesis is seen in plants, algae and some microbes. So, plants are not the only ones carrying out photosynthesis. The basic requirement of photosynthesis is sunlight, water, carbon dioxide and the chlorophyll contained in chloroplasts. Plants fulfil all these requirements, hence photosynthesis is seen in plants.

Does cellular respiration occur in plants?

Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP. This process releases carbon dioxide and water as waste products. … Plants have mitochondria and can perform cellular respiration.

How does photosynthesis occur in plants?

Photosynthesis takes place inside plant cells in small objects called chloroplasts . Chloroplasts contain a green substance called chlorophyll . This absorbs the light energy needed to make photosynthesis happen. … Plants get carbon dioxide from the air through their leaves, and water from the ground through their roots.

Which of the following statements best describe the conditions under which the Calvin cycle and cellular respiration occur in plants?

Which of the following statements best describes the conditions under which the Calvin cycle and cellular respiration occur in plants? The Calvin cycle and cellular respiration both occur in the dark and the light. … They absorb and transfer light energy to the reaction-center chlorophyll.

Where does photosynthesis occur in plants?

chloroplasts
In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.

Under what conditions is aerobic respiration most likely to occur?

It can occur only in the presence of oxygen. It is the formation of ATP by the flow of protons through a membrane protein channel.

In what way are photosynthesis and cellular respiration different?

Cellular respiration produces oxygen, while photosynthesis uses oxygen. Photosynthesis releases energy, while cellular respiration stores energy. Photosynthesis used carbon dioxide, while cellular respiration produces carbon dioxide.

Does cellular respiration occur in plants and animals?

Cellular respiration occurs in the individual cells. … Cells use oxygen to “burn” food for energy. Water and carbon dioxide are produced as wastes. The cells in both plants and animals perform respiration.

Why do plants do both photosynthesis and cellular respiration?

Just like animals can’t live without cellular respiration, plants can’t live without cellular respiration, either. Photosynthesis and respiration in plants are complementary processes because photosynthesis is only one half of the process of getting energy for a plant. It’s how they make food, not how they consume it.

Why do plants need cellular respiration and photosynthesis?

Like all other organisms, plants require energy to grow and thrive in their environment. The process of cellular respiration allows plants to break down glucose into ATP. … Although plants use photosynthesis to produce glucose, they use cellular respiration to release energy from the glucose.

When and why does aerobic respiration occur during cellular respiration in plants?

This only happens during the day, and at night the plant only undergoes respiration, not photosynthesis. Aerobic respiration happens when there is plenty of oxygen (normal level in air is 21%). Anaerobic respiration happens where there is less oxygen than this.

Where does cellular respiration occur?

While most aerobic respiration (with oxygen) takes place in the cell’s mitochondria, and anaerobic respiration (without oxygen) takes place within the cell’s cytoplasm.

Where does most photosynthesis occur?

In plants, photosynthesis generally takes place in leaves, which consist of several layers of cells. The process of photosynthesis occurs in a middle layer called the mesophyll.

Where does most photosynthesis occur in a leaf?

chloroplasts
Photosynthesis takes place inside the chloroplasts that sit in the mesophyll of the leaves. The thylakoids sit inside the chloroplast and they contain chlorophyll which absorbs the different colours of the light spectrum to create energy (Source: Biology: LibreTexts).

Does photosynthesis occur in plants and animals?

Photosynthesis also links plants and animals (such as Dog and Dino) through the air since oxygen released by plants is used not only by plants themselves (for their respiration) but also by animals for their respiration. … Photosynthesis occurs in tiny organelle called chloroplast.

Does photosynthesis occur in plants or animals or both?

Photosynthesis is essential to all life on earth; both plants and animals depend on it. It is the only biological process that can capture energy that originates in outer space (sunlight) and convert it into chemical compounds (carbohydrates) that every organism uses to power its metabolism.

Why do plants go through cellular respiration?

Cellular Respiration and Mass

Virtually all cells, including plant cells, go through cellular respiration to break down food to provide the energy needed for normal functioning and growth. Similar to photosynthesis, the atoms in food molecules are rearranged during cellular respiration.

Where do most reactions of respiration occur?

The mitochondria , found in the cell cytoplasm, are where most respiration happens.

Which one of the following statements best represents the relationship between respiration and photosynthesis?

The answer is (B) Photosynthesis stores energy in complex organic molecules, while respiration releases it.

Which of the following statements best explains why photosynthesis using C4 or CAM systems may be described as a metabolic compromise?

Which of the following statements best explains why photosynthesis using C4 or CAM systems may be described as a metabolic compromise? Both pathways minimize photorespiration but also expend more ATP in the process of carbon fixation.

Which of the following observations would be the best indicator that an organism lacks photosystem ll?

Which of the following observations would be the best indicator that an organism lacks photosystem II? It produces glucose in the light and dark.

What are the 4 main steps of photosynthesis?

It is convenient to divide the photosynthetic process in plants into four stages, each occurring in a defined area of the chloroplast: (1) absorption of light, (2) electron transport leading to the reduction of NADP+ to NADPH, (3) generation of ATP, and (4) conversion of CO2 into carbohydrates (carbon fixation).

Which best describes the nature of cellular respiration?

Which best describes the nature of cellular respiration? It is an energy-releasing process.

What stage of cellular respiration produces the most ATP?

The Krebs cycle
The Krebs cycle takes place inside the mitochondria. The Krebs cycle produces the CO2 that you breath out. This stage produces most of the energy ( 34 ATP molecules, compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle).
