No problem sis :D
Advantages To Asexual Reproduction-
- There is no dispersal in vegatative propogation,hence offspring will grow in the same favourable environemnt as the parent.
-They store large amounts of food that allow rapid growth when conditions are suitable.
Disadvantages To Asexual Reproduction-
-Lack of dispersal in potato tubers can lead to competitions for nutrients,water and light,and will consequently cause the plant to be less healthy.
-There is little variation creted so adaptation to changing environment is unlikely.
-If the parent potato plant has no resistance to a particular disease,none of the offspring will have resistance.
Advantages To Sexual Reproduction-
-There is variation in the offspring so adaptation to the changing or new environment is likely,enabling survival of the species.
-New varieties can be created, which may have resistance to disease.
-In plants, seeds are produced, which allow dispersal away from the plant, reducing competition.
Disadavantages-
-Two parents are usually needed(though not always- some plants can self-pollinate)
-Growth of a new plant to maturity frm a seed is slow.

No problem bro ;)
WARRIOR:
guys is there anything i should kno about graphs in biology? is there anything unique about them? i kno that you have to match points to each other and not make a straight line what else?
The Golden Girl =D:
you should know whe to draw a line , when to draw bars and histograms , other than that I guess , that's all .
