1. Cell: The basic structural and functional unit of all living organisms.
2. Cell Membrane (Plasma Membrane): The semipermeable barrier
that surrounds the cell, controlling the passage of substances in and
out of the cell.
3. Cytoplasm: The gel-like substance within the cell that contains
various organelles.
4. Nucleus: The central organelle that contains the cell's genetic material
(DNA) and controls cell activities.
5. Mitochondria: Organelles responsible for energy production through
cellular respiration.
6. Endoplasmic Reticulum (ER): A network of membranes involved in
protein and lipid synthesis.
7. Ribosomes: Small structures responsible for protein synthesis in the
cell.
8. Golgi Apparatus (Golgi Complex): Organelle involved in
processing, packaging, and transporting cellular materials.
9. Lysosome: Organelles containing enzymes for digestion and waste
removal.
10.Cytoskeleton: A network of protein filaments that provides structural
support and facilitates cell movement.
11.Cell Division: The process by which cells replicate and divide into
two daughter cells.
12.Cell Cycle: The series of stages a cell goes through from its formation
to division.
13.Apoptosis: Programmed cell death, a crucial process in maintaining
tissue homeostasis.
14.Stem Cell: Undifferentiated cells capable of differentiating into
various cell types.
, 15.Cell Signaling: Communication between cells through chemical
signals, regulating cell functions.
16.Cell Adhesion: The ability of cells to stick together and form tissues.
17.Membrane Transport: The movement of substances across the cell
membrane, including diffusion, osmosis, and active transport.
18.Cellular Respiration: The process by which cells generate energy
(ATP) from glucose and oxygen.
19.Cell Differentiation: The process by which cells become specialized
for specific functions in multicellular organisms.
20.Cell Culture: The growth and maintenance of cells outside the
organism in a controlled environment, often used for research.
21.Cell Migration: The movement of cells within tissues, important in
processes like wound healing and development.
22.Cell Adhesion Molecules (CAMs): Proteins on cell surfaces that
mediate cell adhesion and interactions.
23.Cellular Senescence: The state of permanent cell cycle arrest, often
associated with aging.
24.Cellular Metabolism: The set of chemical reactions that occur within
a cell to maintain life.
25.Cellular Stress Response: The cellular mechanisms that protect
against damage and promote cell survival during stress.
26.Cellular Junctions: Specialized structures that connect adjacent cells,
facilitating communication and adhesion. Examples include tight
junctions, adherens junctions, and gap junctions.
27.Cellular Signaling Pathways: Intracellular pathways that transmit
signals from the cell surface to the nucleus, regulating various cellular
processes.
28.Cytokines: Small proteins secreted by immune cells that play a key
role in cell signaling and immune responses.
29.Cellular Metabolism: The chemical reactions that occur within a cell
to maintain energy production and biosynthesis.
30.Cell Cycle Regulation: Mechanisms that control the progression of a
cell through the cell cycle, including checkpoints and cyclin-
dependent kinases.
