33. Why is it beneficial that plants have two kinds of chlorophyll (a and b)?

Answers

Answer:

chlorophyll in plants complement each other in absorbing sunlight.

Explanation:

light with a wavelength of 460 nm isn't always substantially absorbed by means of chlorophyll a, but will as a substitute be captured through chlorophyll b, which absorbs strongly at that wavelength. the two forms of chlorophyll in flowers

It is beneficial to have two kinds of chlorophyll in photosynthetic plants because both types of chlorophyll work complementary to each other and allow maximum absorption of light in the blue to red spectrum.

What do you mean by Chlorophyll?

Chlorophyll may be defined as the green-colored pigment in plants, algae, and cyanobacteria that is essential for photosynthesis.

Chlorophyll A absorbs the light of wavelength 400 to 450nm with maximum intensity and 650 to 700nm with minimum intensity.

Chlorophyll B absorbs the light of wavelength 450 to 500nm with maximum intensity and 600 to 650nm with minimum intensity.

Therefore, it is beneficial to have two kinds of chlorophyll in photosynthetic plants because both types of chlorophyll work complementary to each other and allow maximum absorption of light in the blue to red spectrum.

The structural and functional units of the kidney are called

Answers

Answer:

The structural and functional units of the kidney are called nephron.

Fun Facts about Nephron:

Nephron is the structural and functional unit of the kidney.

Its primary purpose is to maintain the concentration of water and soluble chemicals such as sodium salts in the blood by filtering it, reabsorbing what is needed, and excreting the excess as urine.

The glomerulus and renal (kidney) tubule are the two primary structures in each nephron. Each human kidney contains around 1,000,000 nephrons.

The structural and functional units of the kidney are called the nephrons. Each human kidney contains 8-10 lakhs nephrons.

What do you mean by Kidney?

A Kidney may be defined as a pair of bean-shaped organs that eliminate waste and extra water from the blood and help keep chemicals balanced in the body.

Each nephron contains two structures i.e. Glomerulus and Tubules. The Glomerulus is a tough capillary through which a large amount of fluid is filtered from the blood.

Tubules are the other structure of the nephron in which the filtered fluid is converted into the urine.

Therefore, the structural and functional units of the kidney are called nephrons.
