Organs that collect sunlight |
|
Blade |
Flat main portion of a leaf |
|
Petiole |
Connects the blade to the stem |
|
Flower |
Leaf modified for reproductive purposes |
|

|
Primary roots |
Emerges after germination to grow |
|
Lateral roots |
Emerges from primary roots provides more anchorage and absorption |
|
Monocotyledons |
One seed leaf |
|
Dicotyledons |
Two seed leaves |
