Cell Structure and Function

A cell consists of three fundamental components: the cell membrane, nucleus, and cytoplasm.
The cell membrane acts as a barrier, distinguishing intracellular material from extracellular material, and regulates material exchange.
The nucleus houses genetic material and controls cell growth and reproduction; it is the largest organelle in eukaryotic cells.
Prokaryotic cells are unicellular, while eukaryotic cells can be unicellular or multicellular, encompassing all animals, plants, fungi, and protists.

Eukaryotic vs. Prokaryotic Cells

Eukaryotic cells are defined by their membrane-bound organelles and can be part of multicellular organisms.
Animal cells contain organelles such as the nucleus, mitochondria, Golgi apparatus, and endoplasmic reticulum, surrounded by a plasma membrane.
Plant cells have unique structures like a cell wall and chloroplasts, which are absent in animal cells.
Fungi cells possess a cell wall mainly made of chitin but do not carry out photosynthesis.
Protist cells contain all organelles found in animal cells and may have chloroplasts.

Importance of Cells

Cells are the smallest reproducible units, performing vital roles in the structure and function of living organisms.
They form various body tissues, such as skin, muscle, and bone, which come together to create organs.
Cell communication and connectivity are essential for maintaining the organism's integrity and function.
Human skin consists of numerous specialized skin cells, showcasing the importance of cells in overall structure.
The body continuously replaces cells through division, which is necessary for growth and healing.
