1
Q
Everything has to prosses all 7 things to have lived once, if not then it is not alive but to be dead it also must have done all these things at a point :
A
- Movement
- Respiration
- Sensitivity
- Growth
- Reproduction
- Excretion
- Nutrition
2
Q
movement
A
- an action by an organism causing a change of position or place
3
Q
respiration
A
- the chemical reactions in cells that break down nutrient molecules and release energy
4
Q
Sensitivity
A
- the ability to detect and respond to changes in the enviroment
- humans have 5 senses where as a dog + bat also have Ultrasound
5
Q
growth
A
- a permanent increase in size

- the process that make more of the same kind of organism
7
Q
excretion
A
- removal from organisms of toxic materials and substances in excess of requirements

- taking in of materials for energy, growth and development
9

- shelter
- to hide from predators and to reproduce
10
Q
Name 3 reasons why plants move
A
- plants move towards sunlight which they need to make food
- some flowers close during night
- roots move towards gravity and water
11
Q
Respiration
A
- the process that releases energy from food
12
Q
Oxygen
A
- needed to releases energy from glucose in the body
13
Q
Carbon dioxide
A
- a poisonous by-product of respiration
14
Q
Energy
A
- is needed to do the rest of MRS GREN
15
Q
Transport
A
- systems take materials to and from respiring cells.
16
Q
Food + Oxygen -> Energy + Carbon dioxide + Water
is the equation for the process of what?
A
- Respiration
17
Q
Animal reproduction
A
- all organisms need to reproduce
- reproduction is the making of new organisms
- some animals reproduce by laying eggs - birds
- some animals reproduce by giving birth to live young - mammals
18
Q
Name 3 ways that a plant can reproduce
A
- some plants reproduce using the wind to carry pollen from one flower to another
- some plants reproduce using insects or birds to carry pollen from one flower to another
- insects are attracted to the flowers because of their scent, colour and nectar.
19
Q
What is excretion
A
- excretion is the process where an organism gets rid of waste products that would otherwise cause it harm
- The process that remove waste product from an organism is called excretion
- the waste products in respiration are Water and carbon dioxide
20
Q
Nutrition
A
-Nutrition is the obtaining of food to keep an organsim health
21
