Answer 2

makes proteins

Question 3

Mitocondria

Answer 3

The powerhouse of the cell

Question 4

Golgi Apparatus

Answer 4

Packages protein for distribution outside the cell

Question 5

Endoplasmic Reticulum

Answer 5

Transports materials like protein inside a highly folded membrane

Question 6

Chloroplast

Answer 6

Site of photosynthesis

Question 7

Centrioles

Answer 7

Organelles that occur in Pairs and are important for cell division

Question 8

Cilia

Answer 8

Small hairs around cell for locomotion, also sweeps along surfaces

Question 9

Flagella

Answer 9

Long single hair that acts like an organ for locomotion

Question 10

Cell Wall

Answer 10

A wall that provides shape and protection

Question 11

Lysosome

Answer 11

A vesicle that contains digestive enzymes

Question 12

Vacuole

Answer 12

used for temporary storage/ waste material

Question 13

Nucleus

Answer 13

Control centre of the cell

Question 14

Living organisms need?

Answer 14

energy and water to live, and function

Question 15

Autotrophs

Answer 15

Uses energy from the sun to make sugar/food, this process is also known as Photosynthesis

Question 16

Heterotrophs

Answer 16

Cannot make their own nutrients, so they get it from cellular respiration

Question 17

Parts of the cell membrane

Answer 17

•Phospholipid
•Hydrophilic End (balls)
•Hydrophobic End (tail)
•Glycoproteins for recognition (stacked balls)

Question 18

Passive transport
(Concentration gradient)

Answer 18

-Doesn’t use energy for transportation
-molecules move from high concentration to low concentration

Question 19

3 Types of Passive transport

Answer 19

-Diffusion
-Osmosis
-Facilitated Diffusion

Question 20

Diffusion

Answer 20

Particles that follow a concentration gradient

Question 21

Osmosis

Answer 21

Diffusion of water following a gradient

Question 22

Facilitated Diffusion

Answer 22

Diffusion using a carrier protein in the plasma membrane

Question 23

Active transport

Answer 23

Uses energy for transportation against the gradient

Question 24

3 types of Active transport

Answer 24

-Ion pumps
-Exocytosis
-Endocytosis

Question 25

Average body temp

Answer 25

37°C

Question 26

Ion pumps

Answer 26

Proteins inside the cell membrane which allows passage for certain ions

Ex
•K & Na

Question 27

Exocytosis means

Answer 27

Exo = To leave

Question 28

Endocytosis means? What are 2 other kinds in what forms?

Answer 28

•Endo = To enter
•Pinocytosis = fluid
•Phagocytosis = solid

Question 29

Homeostatic systems

Answer 29

•Homeostasis
•Thermoregulation
•Osmoregulation
•Waste management

Question 30

Thermoregulation

Answer 30

The ability to maintain a constant body temperature

Question 31

Osmoregulation

Answer 31

The ability to maintain a constant water balance

Question 32

Homeostatic

Answer 32

Negative feedback mechanisms. Triggered by Nervous & hormonal mechanisms

Question 33

Homeostasis

Answer 33

Body’s ability to maintain a constant internal environment with a changing external environment

Question 34

Cell theory

Answer 34

•All living organisms are composed of cells
•Cells come from pre-existing cells
•Cells carry out life functions

Question 35

What happens to your body when you get too hot

Answer 35

Change: feeling hot

Receptor: External Epideimis(skin)

Effector: hormones target sweat glands

Change: sweating, later evaporates and cools skin

Normal condition: temps return to normal

Question 36

What happens to your body when you get too cold

Answer 36

Change: feeling cold

Receptor: skin

Effector: hormones cause contractions in muscles

Change: shivering cause muscles to heat up, increasing blood flow

Normal condition: stop shivering, temp returns to normal

Question 37

Positive feedback

Answer 37

-keeps going until normal

Question 38

Negative feedback

Answer 38

-makes adjustments to bring things back to normal
