THE CELL
by: Kory Camp & Liz Doxey
Welcome to the AMAZING Cell!
Cells are the structural and
functional units of all living organisms.
Did you know? That organisms, such as
humans, are multicellular, or
have many cells—an estimated
100,000,000,000,000 cells!
The smallest structural and functional unit of an organism.
The main parts of the cell include
the nucleus, golgi apparatus, ribosome, lysosome,
mitochondria, and the endoplasmic
reticulum.
Golgi Apparatus
“Packaging” and sorts new proteins
for secretion.
Golgi Apparatus: an organelle, consisting of layers of flattened sacs, that takes up and processes secretory and synthetic products from the endoplasmic reticulum and then either releases the finished products into various parts of the cell cytoplasm or secretes them to the outside of the cell.
Mitochondria
The mitochondria is the “Power House” of the cell.
Endoplasmic Reticulum
“ER”Endoplasmic Reticulum: a network of
tubular membranes within the
cytoplasm of the cell, occurring either with a
smooth surface
Smooth ER and Rough ER
Smooth ER has no ribosomes.
Rough ER has ribosomes.
Ribosomes
Ribosome: a tiny, somewhat mitten-shaped organelle
occurring in great numbers in the cell cytoplasm either freely, in small clusters, or
attached to the outer surfaces of endoplasmic
reticula, and functioning as the site of protein
manufacture.
Lysosome
Lysosome: a cell organelle containing
enzymes that digest particles
and that disintegrate the
cell after its death. The
“garbage man.”
NucleusNucleus: is a membrane-
enclosed organelle found in
eukaryotic cells.
Nucleolus
Nucleolus: synthesizes rRNA and it assembles
ribosomes in the nucleus.
Processes of a Cell
The Phases of the Cell
Prophase
Prophase: the first stage of mitosis or meiosis in eukaryotic cell division, during which the nuclear envelope breaks down and strands of chromatin form into chromosomes.
Prometaphase Prometaphase: a stage
sometimes distinguished between the prophase and metaphase of mitosis or meiosis and characterized by disappearance of the nuclear membrane and formation of the spindle.
Metaphase
Metaphase: the stage in mitosis or meiosis in which the duplicated chromosomes line up along the equatorial plate of the spindle.
Anaphase
Anaphase: the stage in mitosis or meiosis following metaphase in which the daughter chromosomes move away from each other to opposite ends of the cell.
Telophase Telophase: the final stage
of meiosis or mitosis, in which the separated chromosomes reach the opposite poles of the dividing cell and the nuclei of the daughter cells form around the two sets of chromosomes.
Cytokinesis
Cytokinesis: the division of the cell cytoplasm that usually follows mitotic or meiotic division of the nucleus.
That’s all folks!
