Aditya Singh Rathore 2 months, 1 week ago

Plants use this to absorb water from the soil to the roots. Osmosis is important to plants because it allows for water uptake, photosynthesis and general stability. Osmosis ensures that all cells and structures within a plant have correct water pressure and volume.

Rashmi Chandola 2 months, 1 week ago

Osmosis = movement of water Molecules from in and out of the cell membrane.

Rashmi Chandola 2 months, 1 week ago

Diffusion = the movement of molecules from higher concentration level to lower concentration level.

Angel Sharma 2 months, 2 weeks ago

Because diffusion is the process of movement of particles ( solids and gases) from higher concentration to lower concentration And Osmosis is the process of movement of water from higher concentration to lower concentration Thus they are so important for the survival of plant cells

Rohit Kumar 1 month, 2 weeks ago

The particles of hot sizzling food possess large kinetic energy so particles diffuse rapidly in air and reaches several meters away but particles of cold food posses less kinetic energy so particles cannot move rapidly in air

Angel Sharma 2 months, 2 weeks ago

Because as the temperature of a substance increases the particles of matter starts moving freely

Jahanavi Pandey 2 months, 3 weeks ago

Reasons behind it- Hot sizzling food have high temperature, so it have high speed and cold food have cold temperature therefore it have low speed

What is universal law of gravitation What is SI unit of m What is positive force

Posted by Aarif Raza 2 months, 4 weeks ago

CBSE > Class 09 > Science

1 answers

Adrija Saha 2 months, 4 weeks ago

The universal law of gravitation states that- Every particle attracts every other particle in the universe with a force that is directly proportional to the product of the masses and inversely proportional to the square of the distance between them. SI unit of m is m/sec. POSITIVE WORK: The work done on an object is said to be positive work when force and displacement are in same direction. Example: When an object moves on horizontal surface, force and displacement acts in same direction. So, work done is positive.
