What is one reason why plants have accessory pigments?

Accessory pigments help plants absorb additional light. Plants need to make these accessory pigments to maximize the amount of photosynthesis they can do. More pigments = More glucose or food for the plant!

What is one reason why plants have accessory pigment molecules like chlorophyll b and carotene?

Calculate the Price

1) Which of the following is an autotroph? pine tree
18) What is one reason why plants have accessory pigment molecules, like chlorophyll b and carotenoids? to absorb energy in parts of the electromagnetic spectrum that chlorophyll a cannot
19) What name is given to a discrete packet of light? photon

Which of the following is true regarding the behavior of a chlorophyll molecule as it absorbs a photon?

Which of the following is true regarding the behavior of a chlorophyll molecule as it absorbs a photon? The energy of a photon raises an electron to the excited state.

Which of the following types of light is least useful for photosynthesis?

Green light is considered the least efficient wavelength in the visible spectrum for photosynthesis, but it is still useful in photosynthesis and regulates plant architecture. Sometimes one may hear that plants don’t use green light for photosynthesis, they reflect it.

Which of the following light is most effective in photosynthesis?

The best wavelengths of visible light for photosynthesis fall within the blue range (425–450 nm) and red range (600–700 nm). Therefore, the best light sources for photosynthesis should ideally emit light in the blue and red ranges.

Why do plants like purple light?

Violet or purple light has a shorter wavelength and higher energy, and is thought to be effective as a secondary light source to facilitate growth and development of a plant’s leafy vegetation.

Are full spectrum grow lights purple?

This makes Valoya’s light a closer imitation of sunlight and a better source of information to plants than red-blue LED lights. The CRI value of Valoya lights is between 60 and 95. This means it appears to human eyes either as a pleasant, soft pink, or even plain white! LED grow lights do not have to be purple.

How many lumens is direct sunlight?

Direct sunlight has a luminous efficacy of about 93 lumens per watt of radiant flux. Multiplying the figure of 1050 watts per square meter by 93 lumens per watt indicates that bright sunlight provides an illuminance of approximately 98 000 lux (lumens per square meter) on a perpendicular surface at sea level.

How many lumens will permanently blind you?

Follow Us: Eighty lumens is sufficient to cause temporary flash blindness in dark conditions, and 200 lumens can cause temporary blindness in daylight. Visible light is not sufficient to cause permanent blindness, regardless of the intensity.
