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)
This is called endocytosis.

Cell Membrane
Adenosine triphosphate (ATP) is a molecule that releases energy to power chemical reactions within a cell. It is commonly referred to as the "energy currency" of the cell due to its role in transferring energy during metabolic processes.
Phagocytosis
Large molecules enter a cell through a process called endocytosis. This involves the cell engulfing the molecule by forming a vesicle around it, which is then brought into the cell. There are different types of endocytosis, such as phagocytosis (engulfing solid particles) and pinocytosis (engulfing liquid particles).
selectively permiable membrane (you might want to double check that though...)
The DNA molecule in a living cell is typically found within the cell's nucleus, packaged into structures called chromosomes. In some organisms, such as bacteria, the DNA may be found in a region called the nucleoid within the cell, which is not surrounded by a membrane.
Phagocytosis Added: A more precise answer here is that this is a form of endocytosis. Phagocytosis usually is particle engulfing without the vesicle, necessarily.
Phagocytosis is called 'cell eating' because it is a process in which a cell engulfs and digests particles or other cells by forming a vesicle around them. This process is similar to a cell 'feeding' on external material by actively engulfing it.
A large DNA molecule is compacted and organized into structures called chromosomes. These chromosomes are further condensed by being wound around proteins called histones, forming a complex called chromatin. This chromatin is then folded and packed into a compact structure that fits within the nucleus of the plant cell.
