|---|---|---|---|---|---|
| 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
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
