eukaruotic cells
As a general rule, practically all the internal organelles of a cell are covered by a protective membrane, except for one type, which couldn't even be called a real organelle, and those are the Ribosomes. More a macromolecular assemble than a cell organelle, the reason because they aren't membrane-bound is because they can directly interact with the membrane in order to exchange proteins, so, having their own membrane would actually act as a barrier for them to do their job correctly.
Having a membrane bound nucleus and many membrane bound organelles would not apply to a prokaryotic cell.
"Analysis of a glandular secretion indicates that it contains some DNA, RNA, and membrane components such as phospholipids. What kind of secretion is this, and why?"
Eukaryotic. Animalia is a kingdom under the domain Eukarya.
Chloroplasts and Mitochondria are the organelles having DNA.
to protect
None. The only part of a prokaryote with a phospholipid bilayer is from the plasma membrane, which is often covered by a cell wall.

No bacterial cell has a nuclear membrane. A bacteria is defined by not having any membrane-bound organelles.
All plant life is eukaryote. Having a membrane bound nucleus and many membrane bound organelles.
The components of the cells which have outer membrane are called membrane bound or membrane enclosed organelles. Example: Nucleus, mitochondria and chloroplast are bound by two membranes. Lysosomes, Endoplasmic reticulum and Golgi-apparatus are bound by single membrane. On contrast ribosomes are not having any protective membrane. Sreekala.K.P

Organisms with nuclear membrane are called eukaryotic cell.

Lysosome ,Centriole, and VesicleActually, animal cells do not have any different organelles than plant cells, other than plant cells having a membrane. animal cells do not have a membrane, they have a cell wall.
It increases the surface area of the cell membrane. By having more surface area, more matter can be moved in and out of the cell.
Instead of having it's genetic material in a membrane bound nucleus and having neatly compartmentalized membrane bound organelles the prokaryotic cell is one big sprawl.
