SNC 1D1 CELL STRUCTURES AS SEEN THROUGH THE ELECTRON MICROSCOPE

ORGANELLE	FUNCTION
cell membrane	Protects cell, allows nutrients to flow in and wastes out
nucleus	The brain of the cell, control centre, reproductive centre
nucleolus	a darker spaces within the nucleus that produces ribosomes
nuclear membrane	Protects nucleus, keeps nuclear material inside,
chromatin	genetic material, material that forms into chromosomes
ribosomes	produce important substances so that the cell works properly
endoplasmic reticulum	is a series of canals that allows transportation of nutrients and other materials
golgi bodies	package and store materials used by the cell
vacuoles	storage areas for food, water, wastes and other fluids
mitochondrion	energy centre for the cell
lysosomes	digestion centre where nutrients are broken down and wastes removed

Similarities and differences between animal and plant cells.

Animal Cells	Plant Cells
Animal cells have only a cell membrane-- no cell wall	have a cell wall (a rigid outer structure made of cellulose)
No chloroplasts	have chloroplasts -- green organelles that contain chlorophyll - a substance used in the process of photosynthesis.
small vacuoles	One large, central vacuole
