Pretty much any living organism produces proteins since proteins are necessary for life. This includes everything from plants to fungi to microbes to cells. Viruses cannot produce proteins in and of themselves since they need their host's ribosomes to make their protein.
No, because not all plants are trees.
Seeds that grow near their parent plants compete with them for light, water, and nutrients. Since the parent plants are older and therefore have a more well developed root system, and a larger leaf area, they tend to have a head start and therefore the younger plants end up to not be able to provide enough light, water, and nutrients for themselves since the parent plant is able to obtain most of it.
Plants have been growing since the Devonian
Since plants are primary producers, these are made to be consumed.
Swans have beaks and such to protect themselves, but they would normally fly away since they are not very good at self defense.

Since they don't have much to protect themselves on their own, they stay together to fend off predators and to have company. They also must protect the little ones. If they were on their own, they would have a harder time surviving. :)
rockfish are not very threatened by their prey, since they are primarily much smaller fish and crustaceans. if you were referring to their predators, they disguise themselves as rocks, hence the name, and are often poisonous.
Since it is the primary prey fish for the entire Gulf of Mexico, I will say it "defends" itself by living in schools and reproducing rapidly.
The cell walls purpose is to protect and to give the plant structure. Since plants don't have bones they need the cell wall to give them support.
Humans and cotton plants have been living on earth since before humans taught themselves to write. The name you seek has been lost to history.
Using simple logic, I would suppose for food and to protect themselves since the sabor tooth tiger probably hunted man.
There are no plants in the deep ocean, since plants need to photosynthesize to survive. There are plants in shallow water since sunlight is easily accessible.
Since parasitic plants live off other plants, they could be said to 'eat' them.
I think Yes, because they are not decomposers since they don't eat dead animals. They are also not producers because only plants produce food for themselves and others.
an attack, because the US didn't have nough military power to protect themselves in the face of war at the time since they were in so much debt and also had no large army
