test tube a) covered completely in
aluminum foil b) not covered in anything c) covered completely in fabric mesh in order? any other points?thank youTo be honest, I am not entirely sure but I do know that for a plant to photosynthesise it needs carbon dioxide, water and lightSo to narrow it down we can cross out A as the
aluminium foil is to block the light and reflect it and the fabric mesh will be making it harder for the light to pass through so therefore the only logical explanation is B - Not covered in anythingI hope this helps! CharlesOther related question
