Some nutrients and other types of particles can be taken into a cell when the cell's plasma membrane encloses the particles and
pinches off, forming a free-floating vesicle inside the cell. A lysosome containing digestive enzymes then fuses with the vesicle. Which term best classifies the uptake of such particles by the cell?
It is one of the processes by which nutrients and other type of particles are taken into the cell.
The plasma membrane invaginates, surrounds and then encloses the macromolecules. It forms the pocket around the macromolecules which is then pinched off to form intra-cellular vesicle.
It is of two types:
Phagocytosis (cell eating): Vesicles formed in this usually merges with lysosomes to form endosomes. Lysosomes provide hydro-lytic enzymes which help in degradation of marcomolecules into simpler units.
Pinocytosis (cell drinking): Vesicles formed are comparatively smaller and usually do not require to merge with lysosomes. These vesicles carry molecules along with extracellular fluids.
Osmosis of Water Across the Membrane. Osmosis is the tendency for water molecules to move from where there is a higher concentration to where there is a lower one. ... The cell membrane helps to regulate and slow down the flow of water into the cell. This is yet another way that the cell membrane helps maintain homeostasis
A sperm cell and an egg cell fuse to form which structure is called a <span>zygote. The zygote is a product of fertilization of two gametes: egg cells for female and sperm cells for males. In this process,the DNA of both cells is passed to the offspring to form a new individual. </span>
