Study Notes

Cell Parts and Their Functions

Cell Membrane: A semipermeable barrier that regulates the entry and exit of substances, maintaining homeostasis within the cell.
Nucleus: The control center of the cell, responsible for managing cellular activities and overseeing reproduction and protein synthesis.
Cytoplasm: A viscous fluid that fills the cell, enabling organelles to remain suspended and facilitating their movement.
Nuclear Membrane: A protective barrier around the nucleus that regulates the flow of materials in and out of it.
Nucleoplasm: The fluid substance within the nucleus, providing medium for the components of the nucleus.
Nucleolus: A structure within the nucleus responsible for synthesizing ribonucleic acid (RNA), essential for protein synthesis.
Endoplasmic Reticulum (ER): A network of membranes facilitating the rapid distribution of materials throughout the cell, existing in two forms: smooth and rough (granular).
Ribosomes: The sites of protein synthesis located on the granular endoplasmic reticulum or floating freely in the cytoplasm.
Golgi Body (Apparatus): An organelle that modifies, sorts, and packages cellular materials for secretion or use within the cell.
Vacuoles: Fluid-filled sacs that store nutrients, waste products, or other materials; often larger in plant cells compared to animal cells.
Mitochondria: Known as the powerhouse of the cell, these organelles are the sites of cellular respiration, where energy is generated, more prevalent in animal cells.
Plastids: Organelles that store pigments and assist in food production and storage.
Chloroplast: A type of plastid containing chlorophyll, critical for photosynthesis, which allows plants to convert sunlight into food.
Cell Wall: A rigid outer layer found only in plant cells, providing support and protection.
