what is another name for them?

Answer 1

Movement                  7            Life Processes
Respiration
Sensitivity
Feeding
Excretion
Reproduction
Growth

Question 2

What is Movement? examples from plants and animals.

Answer 2

the ability of an organism to change position

1) Animals move from place to place
2) Plants open and close petals, and turn to face the sun and grow

Question 3

what is respiration? Why is it needed?

examples from plants and animals

Answer 3

the release of energy from food
Plants and animals need this to stay alive
photosynthesis
Breathing

Question 4

what is sensitivity? examples from plants and animals

what is it also known as?

Answer 4

the ability of an organism to gather information and respond to it
response
Animals can react quickly ex. hearing a loud noise
•Plants react to light, water and gravity slowly

Question 5

what is feeding?
what is it also known as?
example plants + animals

Answer 5

how a living thing takes in food or eats something
nutrition
e.g. plants make their own food using energy from the sun
Animals need to eat plants or other animals to get energy

Question 6

what is excretion?

examples animals + plants

Answer 6

excretion is the removal of wastes that have been made in the body of an animal or plant by means of a chemical reaction
animals = sweat, carbon dioxide, urine and water
plants = Water and oxygen (not much as not much goes in)

Answer 17

MRS FERG

Question 18

what are the eight steps of how to use a microscope?

Answer 18

1. Clean the lens.
2. Make sure lowest power objective lens is over the stage.
3. Switch on the light.
4. Put a drop of water in the middle of the slide.
5. Place a sample in the drop.
6. Lower the coverslip at a 45 degree angle to get rid of air bubbles.
7. Focus on the sample with the lowest power objective lens. Sketch what is seen.
8. Move to the next power objective lens and sketch what is seen.

Question 19

how many stages are involved in using a microscope?

Answer 19

8

Answer 20

.

Question 21

What is reproduction? Why is it needed?

Answer 21

The process of generating offspring

To prevent a species from becoming extinct

Question 22

what is growth? one cell? more?

Answer 22

(biology) the process of an individual organism growing organically and developing into an adult.
gets bigger
Cell division - forms new cells

Question 23

Why do we say living things have sensitivity?

Answer 23

Living things are aware of what is around them

Question 24

how do living things respire?

Answer 24

break down food in their cells to supply themselves with energy

Question 25

How do we know the difference between plants?

Answer 25

Know the difference between them by studying their leaves and flowers

Question 25

What is the difference between the cells of animals and plants?

Answer 25

``` Animals = no cell wall only cell membrane Plants = cell wall outside cell membrane (cell is stronger) ```

Question 27

which is usually more complex, vertebrates or invertebrates?

Answer 27

Question 28

What are the differences between animals and plants (scroll down)

Answer 28

Animals Plants Do not move from place to place Move from place to place Do not make their own food Make their own food Do not carry out photosynthesis Carry out photosynthesis Do not have chlorophyll Have chlorophyll Are non-green Are green Do not have cell walls Have cell walls
