Question 2

whats mrs gren

Answer 2

Movement
Respiration
Sensitivity
Growth
Reproduction
Excretion
Nutrition

Question 3

whats movement

Answer 3

changing your position in response to your surroundings – perhaps to escape from danger or to hunt for food.

Question 4

whats respiration

Answer 4

Respiration releases energy from food stored glucose, reacting with oxygen from breathing, for survival and other processes. Breathing is not the same as respiration

Question 5

whats reproduction

Answer 5

the ability to create offspring, to replace those that have died and ensure survival of the species.

Question 6

whats excretion

Answer 6

…removing waste products from the body.

Question 7

whats nutrition

Answer 7

feeding on food to gain the energy needed for the other processes and nutrients needed to maintain good health.

Question 8

whats tissue

Answer 8

A number of identical cells working together form a tissue.

Question 9

whats organ

Answer 9

A number of tissues form an organ.

Question 10

whats organ system

Answer 10

A number of organs working together form organ systems, which we need to perform the life processes.

Question 11

whats nucleus

Answer 11

Contains DNA; controls the cell’s functions

Question 12

whats mitochondria

Answer 12

Respiration takes place here, releasing energy

Question 13

whats cell membrane

Answer 13

Controls substances entering and leaving the cell

Question 14

whats cytoplasm

Answer 14

Gel-like substance, where most chemical reactions take place

Question 15

what 4 organelles are in animal cells

Answer 15

cytoplasm,cell membrane,mitochondria,nucleus

Question 16

Answer 17

Contains a solution of water, sugars and salts

Question 18

whats cell wall

Answer 18

Made of cellulose, provides support and structure to the cell

Question 19

what 7 organelles are in plant cells

Answer 19

cytoplasm,cell membrane,mitochondria,nucleus, chloroplasts,vacuole,cell wallw

Question 20

true or false bacteria cells are multi cellular

Answer 20

false they are single celled organisms

Question 21

facts about bacteria

Answer 21

Bacteria are small, simple organisms with DNA in the cytoplasm, surrounded by a nuclear membrane, and occasionally possess small hairs called flagella for movement and quick reproduction.

Question 22

what are specialised cells

Answer 22

specialised cells have different shapes or functions that enable them to do a specific job effectively

Question 23

what are the four main types of microorganism

Answer 23

fungi protozoa bacteria viruses

Question 24

what is fungi

Answer 24

fungi are singled celled and invade and absorb their nutrients such as mold

Question 25

what is protozoa

Answer 25

Protozoa are single-celled organisms that are larger than viruses and bacteria. They absorb nutrients from their surroundings. Malaria and amoebic dysentery are caused by protozoa.

Question 26

what is bacteria

Answer 26

Bacteria are also single-celled organisms that live between cells. They grow very quickly under the right conditions. Bacteria cause diseases as cholera and pneumonia, and can also lead to food poisoning.

Question 27

what is viruses

Answer 27

Viruses can only live inside other cells – they invade then destroy the cells, and are responsible for many diseases. Although technically viruses are not living things, we still class them to be microorganisms.

Question 28

what are superbugs

Answer 28

A superbug is a particular strain of a microorganism that has become resistant to treatments – existing medications such as antibiotics could not help the patient.

Question 29

preparing plates science experiment

Answer 29

The lid prevents contamination of the agar in the petri dish, which contains nutrients for microbial growth. The dish is stored in an incubator at a constant temperature, allowing the microbes to reproduce and form a colony when provided with sufficient food, warmth, and oxygen.
