Cell Structure Flashcards
Cell differentiation
The process by which a cell becomes specialised to its function
Cell membrane
A partially permeable barrier that surrounds the cell
Cell wall
An outer, structural layer that surrounds some cells. In plant cells, it is made of cellulose. In fungi, it is made of chitin
Chloroplast
An organelle which is the site of photosynthesis
Cytoplasm
A jelly-like substance that contains all the organelles of the cell, dissolved nutrients and salts
Mitochondria
An organelle which is the site of respiration
Nucleus
An organelle found in most eukaryotic cells that contain the genetic material of the cell and control the activities of the cell
Ribosomes
Organelles that are the site of protein synthesis
Stem cell
An undifferentiated cell that can divide to produce many specialised cells of the same type
Vacuole
An organelle found in plant cells that stores cell sap and supports the cell
