Why are potted plants kept in a dark room?

A leaf picked from a potted plant and when it is preserved in a dark room for some days, it will not move into blue black when tested for starch. As it is preserve in a dark room and there is no light of sun, and the plant was unable to make the food by photosynthesis and starch is the result of photosynthesis.

What happens if a plant is placed in a dark area?

When a plant is kept in a dark room, it will be unable to perform photosynthesis. Without photosynthesis, the plant will not be able to make its own food and the plant will slowly die.

Why was the plant kept in the dark for 48 hours?

Putting the plant in dark for 48 hours would stop the process of photosynthesis as light is required for it. Photosynthesis produces organic sugars which are stored in form of starch in plants. The absence of photosynthesis would lead to consumption of all stored starch making the leaf starchless.

Will a leaf taken from a potted plant kept in a dark room?

No, a leaf plucked from a potted plant kept in a dark room for a few days, will not turn blue black when tested for starch. This is because, since it was kept in a dark room where there was no sunlight, the plant was unable to prepare the food by photosynthesis.

Will a leaf taken from a potted?

Answer : No, a leaf from a potted plant will not turn blue black showing that no starch is present, because the leaf did not get sunlight and it could not make fresh starch food. So, it is necessary for photosynthesis to take place so that starch can be synthesized.

What will happen if we put a potted plant in a closed room?

1) The potted plant which is kept near the window in the room, grows towards light. 2) Auxins act on bending of stem to show a response towards the sunlight. Auxins are synthesized at the tip of the stem (meristematic tissue). 5) Bending of the plant towards light is called phototropism, by the action of auxin.

Why do we get peculiar smell when we shift the potted plants?

Answers. Explanation: We get peculiar smell when we shift the potted plants because the plant excretes waste materials into the soil which gives a bad smell. We get peculiar smell when we shift the potted plants because the plant excretes waste materials into the soil which gives a bad smell.

Why does a potted plant grow towards the window?

Plants need light for the photosynthesis that enables them to live, so they grow in the direction where the light is strongest. Indoors, daylight comes from one side, through a window, so growing plants tend to lean toward the window to reach the strongest sunlight.

Should you rotate potted plants?

Rotating Houseplants The process that causes a houseplant to lean toward light is called phototropism, and it doesn’t actually involve leaning at all. Turning houseplants on a regular basis, however, will help keep your plants looking their best – all of which results in healthier, stronger growth.

How do you straighten a potted plant?

Dig your plant gently out of the ground and reposition it in a sunnier location if its leaning problem was caused by inadequate sunlight. If needed, realign your plant vertically with a stake until it straightens out on its own due to adequate light.

What happens when you put a plant next to a window?

The plant which is kept near the window of the classroom will turn towards the direction of the sunlight. This process is known as phototropism.
