17. Inside the Cell

18. Nucleus
• Almost all cells contain a single nucleus.
• Directs cell activities
• Separated from cytoplasm by nuclear membrane
• Function-Stores and transmits genetic information in the
form of DNA. Genetic information passes from the
nucleus to the cytoplasm
Nucleolus
• Inside nucleus
• Contains RNA to build proteins

19. Nuclear Membrane
• Surrounds nucleus
• Made of two layers
Nuclear envelope
Nuclear pores
• Openings allow material to
enter and leave nucleus

Chromosomes
• In nucleus
• Made of DNA
• Contain instructions for traits &
characteristics

20. Endoplasmic Reticulum
• Moves materials around
in cell
• Smooth type (Agranular):
lacks ribosomes. Site of
lipid molecule
synthesized
• Rough type (Granular):
ribosomes embedded in
surface. Packaging of
proteins to be secreted or
distributed.
http://library.thinkquest.org/12413/structures.html

21. Ribosomes
• Composed of proteins
and several RNA
molecules
• Proteins factories of
the cell
• Either bound to the
organelle or found
free in the cytoplasm
http://library.thinkquest.org/12413/structures.html

22. Golgi Apparatus
• Most cells have
single Golgi
apparatus.
• Protein 'packaging
plant'
• Move materials within
the cell
• Move materials out of
the cell
http://library.thinkquest.org/12413/structures.html

23. Lysosome
• Spherical or oval
• Typical cell may contain
several hundreds
• Digestive enzyme for
proteins, fats, and
carbohydrates
• Transports undigested
material to cell
membrane for removal
• Cell breaks down if
lysosome explodes
http://library.thinkquest.org/12413/structures.html

24. Mitochondria
• Spherical rode like structure
• Produces energy through
chemical reactions – breaking
down fats & carbohydrates
• Controls level of water and
other materials in cell
• Recycles and decomposes
proteins, fats, and
carbohydrates
