How does a plant usually respond to changes?
Plants are able to detect and respond to light, gravity, changes in temperature, chemicals, and even touch. A plant usually responds to change by gradually altering its growth rate or its direction of growth. The slow movements that plants make towards or away from a stimulus, such as light, are known as tropisms.
What are the changes that you observe in the plants?
As a plant grows, it undergoes developmental changes, known as morphogenesis, which include the formation of specialized tissues and organs. Most plants continually produce new sets of organs, such as leaves, flowers, and fruits, as they grow.
How do plants and animals sense their surroundings?
Plants can “see” their neighbors because light reflected or transmitted from nearby plants has a lower ratio of red light to far-red light. The ability of plants to detect red light, far-red light, and their changing closeness to their surroundings is probably one of the most important ways in which plants can sense.
How are treated plants different from control plants?
Students will compare the growth of treated plants to that of the control plants which are grown under optimal conditions. You will then discuss the desirability of breeding new types of plants that are better able to withstand these changes if they occur in the general environment.
How to deal with the effect of drought on plants?
DROUGHT – Maintain these plants in the same environment as the control plants but do not add any water to the container for 3 days. This will allow the pots to dry out at which point the drought treatment will begin. Do not irrigate for a further 5 days.
What do you need to know about water treatment?
Water Treatment 1 Community Water Treatment. Drinking water supplies in the United States are among the safest in the world. 2 Water Fluoridation. Community water fluoridation prevents tooth decay safely and effectively. 3 Consumer Confidence Reports. 4 Household Water Treatment.
How can I change the light quality of my plants?
You can manipulate light quantity to achieve different plant growth patterns. Increase light by surrounding plants with reflective materials, a white background, or supplemental lights. Decrease it by shading plants with cheesecloth or woven shade cloths. Light quality refers to the color (wavelength) of light.
