Yes. If they let anything in or out, the organism would die fairly quickly.
Solid materials
Phagocytosis
yes
Liquid
False. They use endocytosis or phagocytosis for large particles.
All known living things have cells. There are many non-living things that do not have cells.
can be done by molecular sieving, membranes and the sorts
It enters capillaries and is carried to all parts of the body. Then it passes through the cell membranes and is used for building and maintaining the health of the cells. it turnes into a brown solid or waste and then comes out the rectum
They make up structural parts of cell membranes

Blood has red cells and white cells, but I'm not sure what is meant by 'solid part'.
A solid ball of cells is called a morula. A morula is an embryo that is at an early stage of embryonic development.
A solid can pass through a liquid or gas, depending on the properties of both substances. Solids can also pass through some types of filters, membranes, or sieves if they are small enough to fit through the pores. In nature, solid materials can also pass through biological barriers, such as cell membranes or tissues.
Cells make up the solid portion which is 45% of the blood. red blood cells, hemoglobin, whiteblood cells, and platelets.
The three solid components of blood are red blood cells (erythrocytes), white blood cells (leukocytes), and platelets (thrombocytes).
There are no "solids" because they're all in solution; the closest you might come is the membranes of the various blood cells, and/or the (temporarily) unconnected fat molecules that are normally fastened to various transport proteins.
Cells do live in a solid environment. In humans, cells thrive inside the body and are unable to live outside. In plants, cells live in rain forest environments and near rivers, streams, ponds but not in desert environments.
