What characteristics do all plants share
( i know i am giving you the max amount of points and it's not a difficult question so you're welcome )

Plants are the food that animals eat. Plants also provide places for animals, such as insects and birds, to live; many birds build nests in plants. From tiny mosses to gorgeous rose bushes to extremely large redwood trees (Figure below), the organisms in this kingdom, Kingdom Plantae, have three main features. They are all:

1. Eukaryotic.

2. Photosynthetic.

3. Multicellular.

carbon atoms, hydrogen, oxygen, and nitrogen.

above statement is not a true statement about the open ocean because the open ocean has low levels of nutrients. most of the photosynthetic activity on earth occurs in the open ocean within the photic zone. organisms in the deep ocean are exposed to frigid temperatures and total darkness but it does not begin at the low-tide mark.
