                                                   	 2.	 Plants	 need	 energy	 and	 light	 from	 the
                                       Oxygen                            	.

                                                   	 4.	 Plants	 absorb	               	 through	 the
                    Water                               fine	pores	on	the	leaves.

                                                   	 5.	 Plants	absorb	water	and	minerals	through	the
