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
because endocytosis is an active transport process by which large particles enter a cell.
Osmosis, Passive Transport, and Active Transport
exocytosis- particles are expelled from a cell or body- vessicles (sacs) containing the particles fuse with the cell membrane and the contents are expelled endocytosis- particles are induced within a cell- cell membrane forms around them and takes them in: * pinocytosis: engulfing of liquid particles * phagocytosis: engulfing of solid particles (such as a white blood cell engulfing a pathogen)
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).

whats the answer?
The Cell Membrane is the part of the cell that makes lipids and carbohydrates. It transports these parts, as well.
oxygen transport to cell & carbondioxide away from cells.
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
