Plant Questions and Wordle


 

 

1)   What is a vascular plant?

Vascular plants go by the system of tubes to transport nutrients and water into their leaves through the process of photosynthesis.

 

2)   What structures do all vascular plants share?

The structures that all vascular structures share are their cellular levels, conduct photosynthesis, happens in chloroplast with the help of chlorophyll molecules, same structures called roots, stems and leaves.

 

3)   What are the roots designed to do?

Roots are designed to pull water and minerals from whatever material the plant sits on.  They support the plants in the form of an anchor in the soil.

 

4)   What are the two jobs of the stem?

The two jobs of the stem are transporting food and water and acting as a support structure.

 

5)   What are the jobs of the xylem vessels?

The jobs of the xylem vessels are that it transports cells that circulate water and dissolved minerals and they also support the tree.

 

6)   What does the phloem transport?

Phloem transports the sap that comes out of a tree.

 

7)   What is the job of chlorophyll?

The job of chlorophyll is capturing light from the sun.

 

8)   In photosynthesis, what molecules combine together to form what compounds?

Carbon dioxide and water combine with light to create oxygen and glucose. That glucose is used in various forms by every creature on the planet.

Food Web in the Sagebrush-Steppe Ecosystem

1)
a - Squirrels and other small rodents, insects, pronghorn and other grazers.
b - Badger and raptor
c - Bats, lizards and small reptiles
d - no one 

2) The coyote eats lizards and other reptiles who also eat insects, so this will effect both animals because there will be a lot more of them. The mountain lion would be affected because i also eats the pronghorn and other grazers. 

3) If there was an increase in mountain lions there would be a lot less pronghorns and other grazers around because they are the only animal that the mountain lion eats.

4) The effects the mesquite trees would have on the ecosystem is they take so much water form the soil that plants won't be able to grow quickly. However they are edible so they would be very useful to humans and they also produce seed pods which are eaten by animals and they're good because they put nutrients back into the soil. So the only down part is for the plants.
