| What are the vascular tubes of tracheophytes called, what are their specific jobs, and where in the vascular bundle are they located? | Xylem-located in the inner layer of the vascular bundle and responsible for transporting water and nutrients up from the roots to the rest of the plant.
🗑

||||
| What are the vascular tubes of tracheophytes called, what are their specific jobs, and where in the vascular bundle are they located? | Phloem-located on the outer layer of the vascular bundle and responsible for transporting food down from the leaves to the rest of the plant.

🗑
|
||||
| What method does a tracheophyte use to obtain its water/food? | A vascular system of xylem and phloem

|
||||
| All angiosperms produce___ and have seeds encased in ___. | flowers, fruit
🗑
|
||||
| How is an angiosperm determined to be a monocotyledon or a dicotyledon if you can only examine the seed? | Mono means one: therefore if the seed only has one cotyledon it is a monocot. Di means two, so if it has two cotyledons it is a dicot.

🗑
|
||||
| What if you could only examine the flowers? | Monocots are in multiples of 3, 6, and 9, whereas dicots usually have petals in groups of 4 or 5.

||||
