how is the structure of a leaf optimized for photosynthesis

Answers

Answer:

- The upper epidermis of the leaf is transparent, allowing light to enter

- They have a large surface area to volume ratio, allowing more light to enter

The upper epidermis of the leaf is transparent, allowing light to enter and they have a large surface area to volume ratio, allowing more light to enter.

What is responsible for photosynthesis to occur?

The mesophyll cell is responsible for photosynthesis occurs. The majority of the chloroplasts and the primary site of photosynthesis are located in the palisade layer. The area of storage and gas exchange is the airy, spongy layer. The stomata control the water and carbon dioxide equilibrium.

For gaseous exchange and photosynthesis, leaves are suited. Since they have a wide surface area and stomata, which enable carbon dioxide to enter the leaf and oxygen to exit, they are well-equipped for photosynthesis.

Chloroplasts, which is known as the house the chlorophyll in plants, are where photosynthesis occurs. The thylakoid membrane, a third inner membrane that creates lengthy folds inside the chloroplast and is bordered by a double membrane, is present inside chloroplasts.

Therefore, The upper epidermis of the leaf is transparent, allowing light to enter and they have a large surface area to volume ratio, allowing more light to enter.

What is the main purpose for plants to conduct photosynthesis?

Answers

Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.

why do heart cells have a higher percentage of mitochondria than liver and pituitary gland cells?

Answers

Answer:

This is because the heart requires large amounts of energy in order to pump blood to the rest of the body. The mitochondria produces ATP for energy, thus heart cells contain a higher percentage of mitochondria for energy to pump blood.

The heart cells have a higher percentage of mitochondria than liver and pituitary gland cells because the heart requires large amounts of energy in order to pump blood to the rest of the body. The mitochondria produces ATP for energy, thus heart cells contain a higher percentage of mitochondria for energy to pump blood.

What is the role of mitochondria in producing energy?

The role of Mitochondria in producing energy are in charge of producing energy as ATP. The heart muscle has the highest energetical requirements. Several mitochondria compose these muscle cells because too much energy is needed to pump blood constantly.

Mitochondria are known as the one of the biggest organelles in the cell. They are semi-autonomous organelles surrounded by a double membrane that reproduce by binary fission and contain their own DNA, RNA, and ribosomes. Mitochondria are in charge of aerobic cell respiration, the process by which cells use organic compounds and turn them into energy.

Therefore, The mitochondria produces ATP for energy, thus heart cells contain a higher percentage of mitochondria for energy to pump blood.

now you’ll examine an operon that undergoes negative and positive control. the ara operon in e. coli codes for enzymes that metabolize the sugar arabinose, which e. coli can use for energy. as you can see in the diagram, the regulatory protein arac can act as both an activator and a repressor of the ara operon.

Answers

The lac operon is known to be able to undergoes negative and positive control.

The diagram based on the 4 table arrangement is filled up below (Right to left);

In the presence of arabinose:  initiator, activator,  yes,  yes.

In the absence of arabinose: initiator and operator, repressor, no, no.

If a mutation prevents arabinose from biding to AraC: initiator and operator, repressor, no, no.

If arabinose is present but a mutation and AraD enzyme renders it non-functional: initiator, activator, yes, no.

The metabolism of the sugar arabinose is known to be influenced  by an operon that is said to undergo both positive control and negative control.

Transcription of the ara operon is lead by the regulatory protein AraC, which then bound to the DNA.

When arabinose is present, it binds to AraC, and both parts of the AraC dimer are then also bound to the initiator, making transcription to move foreword.

When arabinose is absent, one part of the AraC dimer is often bounded to the initiator, while the other part is bounded to the operator, thereby hindering transcription.
