Download Cell anatomy and cell division

Anatomy of the Cell



Nucleus – headquarters of cell, contains DNA
(chromatin)
Cytoplasm – site of most cellular activities
Plasma membrane –
separates cell contents
from environment
Get into groups of 2 and determine main
functions of organelle or structure:
-ribosomes
-peroxisomes
-endoplasmic reticulum
-Golgi apparatus
-lysosomes
-mitochondria
-cytoskeleton
-centrioles
Cell Division




DNA replication
Mitosis – division of
nucleus
Cytokinesis - division of
cytoplasm
End product: 2 daughter
nuclei with identical
genes as mother
Interphase-growth, cell spends most time
Prophase-chromatin to chromosomes, centrioles
direct formation of mitotic spindle
Metaphase-chromosomes align at metaphase plate
Anaphase-centromeres split, daughter
chromosomes move to opposite ends of cell
Telophase-chromosomes to chromatin
Cytokinesis-cleavage furrow, division of cytoplasm
