1. Estimate different types of tropic movements in plants.
Happy Learning!😊

COORDINATION IN PLANTS

RESPONSE TO STIMULUS

Plants show response to a stimulus either by going towards the stimulus or away from the stimulus. these are directional movements or tropic movements.




1.


The stem is positively phototropic.
Roots are negatively phototropic 

2.


Roots are positively geotropic.
The stem is negatively geotropic 


3.

Roots are positively hydrotropic.
The stem is negatively hydrotropic 


4. It is the response of the plants towards the chemicals. Eg. the pollen tube grows towards the chemical produced by style during fertilization.


5. The turning or bending of a plant or other organism in response to a touch stimulus.

SOURCES OF ENERGY     Important Instructions: (i) Keep your text book open for reference. (iv) Home Assignment need to be done in your physics note book. (v) Complete your index, put chapter name, date, Physics note book. (vi) Important links are provided in the blog for better understanding. Home Assignment to be done in the Physics copy  After this class, you will be able to: identify the parameters needed to classify a source as a good energy source. interpret the advantages of using fossil fuels, thermal power plants and hydro power as sources of energy INTRODUCTION Energy is the ability to do work or the total power derived from our natural resources.  The energy exists in many forms and can be converted from one form of energy into another.  Energy is mainly derived from natural sources like the sun, oceans, fossil fuels, wind etc and is converted into electrical energy that we consume for our daily needs and benefits.

SOURCES OF ENERGY Lesson 4    Hello everyone! I hope you are keeping well and taking good care of yourself! Learning outcomes : explore alternate sources of energy giving prime importance to environmental  conse q uences All  energy sources  have some  impact  on our  environment .  Fossil fuels—coal, oil, and natural gas—do substantially more harm than renewable  energy sources  by most measures, including air and water pollution, damage to public health, wildlife and habitat loss, water use, land use, and global warming emissions. No source of energy can be called pollution-free, because, the use of any source of energy disturbs the environment in one way or the other.  A source of energy like a solar cell is pollution free in actual operation but the assembly of the device might have caused some damage to the environment. So, in absolute sense,  no source of energy can be called pollution free. NCERT Page 253   Q. Hydrogen

At the end of this class, you will be able to: 1. Estimate different types of plant hormones and their functions. 2. Explain the release of Auxin. Happy Learning!😊 PLANT HORMONES Chemicals that help plants to coordinate their growth and various other activities are called plant hormones. They are secreted in small amounts by some specialized parts of the plants. (to be written in bio notebook) Release of Auxin 1. When a growing plant detects light, auxin synthesizes at the shoot tip. 2. It helps the cell to grow longer. 3. When light is coming from one side of the plant, auxin diffuses towards the shady side of the shoot. 4. The concentration of auxin stimulates the cell to grow longer on the other side of the shoot which is away from light. 5. Thus
