Q

WHAT ARE RIBOSOMES

A

SMALL ORGANELLES WHERE PROTEIN ARE MADE IN THE CELL

17
Q

WHAT OTHER ORGANELLES DOES PLANTS HAVE APPART FROM THE ANIMAL ONES

A

CHLOROPLASTS
CELL WALL
VACUOLE

18
Q

WHAT ARE CHLOROPLASTS

A

CHLOROPLASTS CONTAIN A GREEN SUBSTANCE CALLED CHLOROPHYLL WHICH IS USED IN PHOTOSYNTHESIS

19
Q

WHAT IS A CELL WALL

A

A RIGID STRUCTURE MADE OF CELLULOSE, WHICH SURROUNDS THE CELL MEMBRANE.

20
Q

WHAT DOES A CELL WALL DO

A

IT SUPPORTS THE CELL AND STRENFTHENS IT

21
Q

WHAT IS A VACUOLE

A

A LARGE ORGANELLE THAR CONTAINS CELL SAP (A WEAK SOLUTION OF SUGARS AND SALTS)

22
Q

WHAT DOES A VACUOLE DO FOR THE CELL

A

IT HELPS TO SUPPORT THE CELL

23
Q

WHAT IS A TISSUE

A

A TISSUE IS A GROUP OF SIMILAR CELLS THAT WORK TOGETHER TO CARRY OUT A PARTICULAR FUNCTION

24
Q

WHAT DOES THE PLANT (XYLEM TISSUE) DOESS

A

IT TRANSPORTS WATER AND MINERALS

25
Q

WHAT CAN A TISSUE CONTAIN

A

MORE THAN ONE CELL TYPE

26
Q

WHAT IS AN ORGAN

A

A GROUP OF DIFFERENT TISSUES THAT WORK TOGETHER TO PERFORM A FUNCTION

27
Q

ORGANS WORK TOGETHER TO FORM (…)

A

ORGANS SYSTEMS

28
Q

WHAT DOES ORGANS SYSTEMS DO

A

EACH SYSTEM DOES A DIFFERENT JOB
FOR EXAMPLE: IN MAMMALS THE DIGESTIVE SYSTEM IS MADE UP OF ORGANS INCLUDING THE STOMACH, INTESTINES, PANCREAS AND LIVER
