Need Help fast!!! my son's Science project question. Plants.?

Question

Ok so the question is Can plants grow in a dark environment with only a small amount of sunlight? This is my son's project. So we did the project. Put 2 plants in boxes with a small hole at the top and put the 3rd plant in the light. A&B (the plants in boxes grew faster) and C (the one in the sun ) grew a little slower, but was definetly in better condition. ( I know this is because clorophyll absorbes energy from the sun which gives the plants it's green color). The other 2 in the boxed grew taller (trying to reach for the light and climbed out of the top of the box) although the stems are pale. So can the plants still survive with only a small amount of light or will they eventually die? Best answer gets 10 pts

By the wat this is 4th grade so try not to make it hard to understand.

By the way this is 4th grade so try not to make it hard to understand.

Ok update. This is a regular old garden bean plant. Planted in regular soil. This is the project is due tomorrow, so any help would be appreciated. Thanks!

Answer 1

The answer to the question is NO. It can live only very shortly after it sprouted while it still have its stored energy previously stored in its seeds.

When seeds are planted they do not need light to germinate because they are planted beneath the soil, where it is already dark. Seeds contain a plant embryo and stored food to give the baby plant all the energy it needs to sprout. After the seeds sprout the plants do need light to grow.

Light is needed for the plants to produce their own food through photosynthesis. Shortly after sprouting the plant grown in the dark will grow just as the ones in the light and partial light because they all have stored energy from their seeds, but the plant grown in the dark will not have any color -it will have a faint yellow-green color but taller and trying to catch some sunshine to survive. The plant grown in the light will have the healthy green color of a plant capable of photosynthesis.

Over time the plant growing in the light will continue to use the light to produce its own food and it will grow, but the plants grown without full light will die since they cannot produce food without light.♥

Answer 2

The hole let in real bright white light and lead the plant toward the hole!

If you would put a real dark filter across the top of the box like a sunglass that would slow down the growth!

The problem was that the plant saw the bright white light and grew toward it that is called photo tropism where something grows toward light! A tree grows up straight against the earths gravity that is called geo tropism! (photo = light geo = earth like the study of the earth is geology!)

The filter needs to cover the whole end of the box evenly so the plant would not grow crooked!

Look you can use this experiment to demonstrate phototropism ! How a plant grows toward light! Rather than the first thing!!!!

That is the real name of what you have demonstrated! Hey scientist discover things every day by accident!!!!!

Look up PHOTOTROPISM let that be his project! It looks fancy!

By the way to demonstrate GEOTROPISM you grow a plant on the outside edge of a record player turning at 33 1/3 what happens is the plant grows into the center of the record player! It thinks that the middle is UP! That is a fun one to try! If you have a old record player try that one! There will be many many more Science Fairs!

Good Luck

Answer 3

The answer depends somewhat on the plant used but...eventually, if the plant does not get enough sunlight to meet its basal metabolic needs (maintenence, repair, etc.) then it will die. The reason that the plant in the dark grew a very long stem was to try to reach sunlight (much as if it had sprouted under a dense tree). It used the energy stored in the seed (cotyledon) to grow, but the seed energy is finite.

Answer 4

Hi:
Accord to your test result yes depending a how long you exposed the plants to light and they will grow to reach the light to get more of it, this is what your project was to tell you . but for better result try this instead, give plant Number 2 a short amount of light record how long you let it out in the light and how tall it grew and put it in boxes without any holes so it doesn't get any more light than what you want to give it and the next day repeat the experiment again the same way you did it yesterday. Be sure to date and record the growth and make any notes of what happens to the plants and give plant # 1 and even shorter amount of sunlight and record it results along with the control plant # 3 then you should get good result a be able to draw your own concluctions

For example:

Plant # 1 - Day 1 one hour of sunlight in the full sun 1:00pm to 2:00pm measured growth 4.5 inch on May 5,2005 return to box at 2:00pm- Note all leaves green - Start of experiment

plant #2 - Day 1- four hours in the full sun from 1:00 pm to 5 pm measured growth 5 inch on May 5, 2005 return to box at 5:00 pm Note all leaves green - Start of experiment

Plant #3 - Day 1 full sunlight all day in sun 7:00am - Full sunrise to 5:30 pm full sun set measured growth 5.5 inches on May 5,2005
Note - all leave green Start of exiperiment



{I didn't have time to type of this out So I slipped three day of recording here but you do the same thing, recording all results and dating it}





Day 4

Plant # 1 - One hour of Sun light from 1:00 am to 2:00 pm, measured growth 4.5 on May 9,2005; return to box at 2:00pm
Note some browning and lighten of leaves

Plant #2 - four hours of sun from 1:00pm to 5pm measured growth 5.8 inches on May 9,2005 Return to box at 5:00pm Note-

Slight whiting of the leaves but still as green leaves and looks better then Plant #1


Plant #3 - Full sunlight all day- from 7:00am - full sunrise until 5:00 pm returned to box on May 9,2005,- Measured growth 6.7 inch- Note all leaves green in the best of health

Answer 5

some kinds of vegetation can't have a super form of solar using fact they're overwhelmed, particularly smaller vegetation. The photosynthesis technique occurs for too long of a era of an afternoon and the quantity of clorophyl turns into poison to the plant. on your occasion, constrained quantities of sunshine are greater useful that finished photograph voltaic. using fact the plant with constrained mild gets better it extremely is going to require greater photograph voltaic using fact it extremely is going to require greater clorophyl. back, too lots isn't good. over the years using fact the plant gets better, it extremely is waiting to handle finished solar, yet purely after it has grown to a lots better length. The plant that gets finished solar will extremely die quicker.

Answer 6

1st of all, jen jen, you are very hot, 2nd of all, as a plant specialist, it would depend on the species. some species are shade tolerant, some need full sunlight, some need certain temps, some can only grow in certain ground types, black dirt, sandy soils and other types vary. there is no way to know unless you are specific.
