biology question #2380



Tom Henson, a 14 year old male from Bettendorf, Iowa asks on November 27, 2004,

Q:

I am doing a science project on how light affects plant growth. If you could answer my 10 questions it would be a great help: 1.Does light color effect plants? 2.Can a lightbulb support plantlife? 3.Do they make lightbulbs to simulate sunlight? 4.Do these lightbulbs work well? 5.Is there a type of substitute lightbulb that you would reccomend? 6.Is it neccassary to simulate night and day when the plants are under bulblight? 7.Will a plant under bulb grow less than a plant in the sun? 8.Can a plant die from to much light? (assuming they are watered regularly) 9.Does the watt of a lightbulb effect the plant? 10.Would you reccomend a lamp shade or other coverign to soften a lightbulb's light?

Question: I am doing a science project on how light affects plant growth. If you could answer my 10 questions it would be a great help: 1.Does light color effect plants?

Yes

2.Can a lightbulb support plantlife?

yes

3.Do they make lightbulbs to simulate sunlight?

yes

4.Do these lightbulbs work well?

yes

5.Is there a type of substitute lightbulb that you would reccomend?

go to www.google.com and type in: growing plants under lights

6.Is it neccessary to simulate night and day when the plants are under bulblight?

yes--for some plants the length of day is important for flowering or fruit.

7.Will a plant under bulb grow less than a plant in the sun?

It depends what kind of plant and bulb. In general sun is best.

8.Can a plant die from too much light? (assuming they are watered regularly)

yes

9.Does the watt of a lightbulb effect the plant?

yes, the more watts the more growth--to a point.

10.Would you reccomend a lamp shade or other coverign to soften a lightbulb's light?

Probably does not matter.
