| Question | Answer |
|---|---|
| WHAT IS THE FUNCTION OF THE ROOTS | ABSORB WATER AND MINERALS ANCHOR AND SUPPORT PLANT STORE CARBS, H2O AND OTHER NUTRIENTS |
| WHAT ARE THE STRUCTURES OF THE ROOT | ROOT CAP ROOT HAIR EPIDERMIS CORTEX ENDODERMIS VASCULAR TISSUE |
| WHAT IS THE ROOT CAP? | THE PARENCHYMA CELLS PROTECTING THE GROWING TISSUES AT THE END OF THE MAIN ROOTS BY PRODUCING A SLIMY SUBSTANCE THAT REDUCES FRICTION |
| WHAT IS THE ROOT HAIRS | THEY ARE TINY EXTENSIONS OF THE EPIDERMAL CELLS OF THE ROOTS AND THEY INCREASE THE SA TO INCREASE ABSORPTION |
| WHAT IS THE EPIDERMIS | IT IS THE SINGLE LAYER OF CELLS COVERING ROOTS |
| WHAT IS THE CORTEX | PARENCHYMA CELLS TRANSPORTING AND STORING WATER AND MINERALS |
| WHAT IS THE ENDODERMIS | ONE CELL THICK EACH CELL SURROUNDED BY A CASPARIAN STRIP (WATERPROOF BAND, HELPS FORCE WATER AND MINERALS TO PASS INTO VASCULAR TISSUE) |
| WHAT IS THE VASCULAR TISSUE | FOUND IN THE CENTRE OF THE ROOT TWO TYPES MONOCOT: XYLEM FORM A RING AROUND THE PTIH DICOTS: XYLEM FORM AN X OR STAR SHAPE WITH THE PHLOEM INBETWEEN |
| WHAT ARE THE TYPES OF ROOT SYSTEMS | TAPROOT FIBROUS ROOT MODIFIED ROOT |
| WHAT IS A TAPROOT | ONE MAIN THICK ROOT GROWING DEEP INTO SOIL SMALLER LATERAL BRANCHING ROOTS ABSORBS WATER, MINERALS, ANCHORS PLANT AND STORES STUFF |
| WHAT IS FIBROUS ROOT | MANY EQUAL SMALLER BRANCHING ROOTS SHALLOW ABSORB WATER AND MINERALS AND ANCHORS PLANT |
| WHAT IS MODIFIED ROOT | MODIFIED TO PROVIDE EXTRA SUPPORT OR STORE FOOD AND WATER IE. PLANTS IN DRY REGIONS AND SWEET POTATOES |
