Cells can take in solids by the process of endocytosis.
The cell membrane (plasma membrane) folds in, surrounding the solids, and pinches off to form a vacuole in the cytoplasm. The cell then secretes enzymes into the vacuole, and any digestible compounds in the solids are broken down and absorbed across the vacuole membrane into the cytoplasm.
There are two types of endocytosis:
if solids are taken in, the process is phagocytosis;
if the vacuole contents are entirely liquid, it is pinocytosis.
Endocytosis - Phagocytosis
The process that transports particles through the cell membrane between phospholipid molecules is called passive diffusion. In passive diffusion, particles move from an area of higher concentration to an area of lower concentration without the need for energy input.
Eventually, the concentration of particles inside and outside the cell will reach a state of equilibrium, where the concentration of particles is equal on both sides of the cell membrane. This process occurs through diffusion, where particles move from an area of higher concentration to an area of lower concentration. However, if the cell actively transports certain particles, the concentrations may remain unequal, depending on the cell's requirements and the specific substances involved.
Phagocytosis (cell eating) - form of endocytosis(folding in of cell membrane to trap material from the outside) ; cell membrane engulfs solid particles by wrapping around itPinocytosis (cell drinking) - form of endocytosis; cell engulfs liquids by sucking it in
The movement of large particles of solid food or whole cells into the cell is called phagocytosis. Phagocytosis occurs in three separate steps.
When a cell needs to take in a particle larger than the membrane channels can passage, it will invaginate the cell membrane around the particle(s) and pinch off part of the membrane containing the particles inside the cell membrane. This is called phagocytosis (when the particles are primarily solid) or pinocytosis (when the particles are primarily liquid).

The Cell Membrane is the part of the cell that makes lipids and carbohydrates. It transports these parts, as well.
The movement of large particles of solid food or whole cells into the cell is called phagocytosis. Phagocytosis occurs in three separate steps.
