Why do some plants have more chloroplasts than others?

Chloroplasts are only found in the parts of the plant that are capable of photosynthesis. The majority of chloroplasts are found in the leaves of the plant because these structures have the greatest surface area for absorption. The outer part of a plant stem may also contain chloroplasts.

Why do plants have different types of chlorophyll?

Green light is not absorbed but reflected, making the plant appear green. The two kinds of chlorophyll in plants complement each other in absorbing sunlight. Plants are able to satisfy their energy requirements by absorbing light from the blue and red parts of the spectrum.

Why plants have two types of chlorophyll instead of just one How does this benefit them what would you expect concerning the rate of photosynthesis for a plant that had only one type of chlorophyll?

1 Expert Answer Chlorophyll a and b absorb a slightly different range on light wavelengths. Assuming the incoming light is white, a plant that had only one type of chlorophyll would extract less energy from the white light of the sun and have a lower relative rate of photosynthesis compared to a plant with two.

Why do plants have more than one photosynthetic pigment?

Chlorophyll a is the most common of the six, present in every plant that performs photosynthesis. The reason that there are so many pigments is that each absorbs light more efficiently in a different part of the electromagnetic spectrum.

What is the functions of chlorophyll?

Chlorophyll’s job in a plant is to absorb light—usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose, a type of sugar.

Is P680 chlorophyll A or B?

P680 is composed of chlorophyll a molecule which, after excitation by the absorption of light to form P680*, gives up an electron to an acceptor, converting it to P680•+. This radical cation has a redox potential estimated to be ~1.2 V or more, which is required to oxidize water.

What type of chlorophyll is in the reaction center?

Chlorophyll A is used in the reaction center. The other pigments absorb the light from the sun that chlorophyll cannot. They then transfer energy to chlorophyll a to be released to the positive electron acceptor. The wavelengths of light will alter the rate of photosynthesis in a plant.

What is the difference between a chloroplast and chlorophyll?

Chlorophyll refers to a pigment responsible for the green colour in plants. Chloroplasts are organelles within a plant cell, acting as the site for photosynthesis. Pigment necessary for photosynthesis. Chloroplast is the region where photosynthesis occurs.

Does chlorophyll have DNA?

A chloroplast is a type of organelle known as a plastid, characterized by its two membranes and a high concentration of chlorophyll. Chloroplasts, like mitochondria, contain their own DNA, which is thought to be inherited from their ancestor—a photosynthetic cyanobacterium that was engulfed by an early eukaryotic cell.

Does the chloroplast make chlorophyll?

In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. The green pigment chlorophyll is located within the thylakoid membrane, and the space between the thylakoid and the chloroplast membranes is called the stroma (Figure 3, Figure 4).
