There exists a widespread controversy over stem cell research that emanates from the techniques used in the creation and usage of stem cells. Embryonic stem cell research is particularly controversial because, with the present state of technology, starting a stem cell line requires the destruction of a human embryo and/or therapeutic cloning. Opponents of the research argue that this practice is a slippery slope to reproductive cloning and tantamount to the instrumentalization of a human being. Contrarily, medical researchers in the field argue that it is necessary to pursue embryonic stem cell research because the resultant technologies are expected to have significant medical potential, and that the embryos used for research are only those meant for destruction anyway (as a product of invitro fertilisation). This in turn, conflicts with opponents holding an anti-abortion stance, who argue that an embryo is a human being and therefore entitled to dignity even if legally slated for destruction. The ensuing debate has prompted authorities around the world to seek regulatory frameworks and highlighted the fact that stem cell research represents a social and ethical challenge.

only plant cells ? sorry.
but stem cells do not belong in plants, the main contention with ethical issues is that stem cells come from "embryos" , so the problem is with "EMBRYONIC stem cell research".

instead stem cells are extracted from human embryos ( which are fertilised eggs in the blastocyst stage, which go on to develop normally into a fetus > baby, fully-formed human, etc)

How can it benefit humans?

* Embryonic cells are able to divide into any of the 220 cells that exist in the body
* This means that embryonic stem cells can be used to treat virtually any condition or degeneration that has occurred in the human body
* They can be used to recreate genetically identical limbs or organs that will not be the body's immune system
* Previously, brain diseases and spinal cord have been incurable, stem cells in the future might have the cure to treating such conditions

In terms of Opposition:
the main ethical issues are:
- you are destroying/killing a potential "human" , a human embryo develops into a fetus > thus human given time, is it alright to extract stem cells from the embryo? (which dies once the stem cells are extracted) or
- Inhumane to doom a follow human's existence in the course of research
- Human Life becomes much more dispensable
- Links to human cloning
- The DNA fingerprint left behind on it can be used to identify the donor of the embryo

it is more of an argument taken from a religious point of view

you should google up the issue
