Water

Question 1

What is the first reason of importance of water for living organisms?

Fizz, Pop, Bang

Answer 1

Is a reactant for many chemical reactions, including photosynthesis and hydrolysis. As well as many chemical reactions taking place in water (cytoplasm).

Question 2

What is the second reason of importance of water for living organisms?

Love the North Pole

Answer 2

It’s a polar molecule so allows water to act as a solvent as polar substances are attracted to it.

Question 3

Water is a polar molecule which mean it can be…

Buses and Fizz, Pop, Bang

Answer 3

-Transported around organisms-Absorbed into root hair cells-Used in reactions

Question 4

The polarity of water allows it to form bond with which type of molecules?

2 types

Answer 4

Hydrogen bonds with other water molecules (cohesion) and other types of molecules (adhesion).

Question 5

What is the third reason of importance of water for living organisms?

Heat Climate probe

Answer 5

It has a high specific heat capacity. So water therefore doesn’t experience rapid changes in temperature.

Question 6

Water doesn’t experience rapid changes in temperature due to it’s high specific heat capacity which…

temperature

Answer 6

-aids thermoregulation-provides a fairly stable environment for aquatic organisms.

Question 7

What is the fourth reason of importance of water for living organisms?

Dissapearing, cold

Answer 7

It has a high latent heat of evaporation. So is good for cooling animals and plants.

Question 8

What is the fifth reason of importance of water for living organisms?

Chemistry

Answer 8

It’s dense as a liquid but expands (less dense) when it freezes.
