function Check_Callback(hObject, eventdata, handles)

blah = get(blah,'String');
leaf1 = 'Parsley';
leaf2 = 'Coriander';
tf = strcmp(blah,leaf1);
tf2 = strcmp(blah,leaf2);
result1 = 'You are right, it is a parsley leaf';
result2 = 'You are right, it is a coriander leaf';
result3 = 'You are wrong, it is a parsley leaf';
result4 = 'You are wrong, it is a coriander leaf';
if (G <=  200 && tf == 1)
    set(handles.text3, 'String', result1);
else if (G > 200 && tf1 == 1)
        set(handles.text3, 'String', result2);
else if (G <=  200 && tf1 == 0)
    set(handles.text3, 'String', result3);
else if  (G > 200 && tf1 == 0)
        set(handles.text3, 'String', result4); 
    end
    end

If you are using GUIDE then use guidata. If you are sensibly writing your own code then use nested functions. Both of these are explained in the documentation:
