Page 1: The “brain” of the cell Large, spherical Contains DNA Enclosed in a double- layered nuclear membrane
Page 2: The “brain” of the cell Large, spherical Contains DNA Enclosed in a double- layered nuclear membrane

•The “brain” of the cell

•Large, spherical

•Contains DNA

•Enclosed in a double-layered nuclear membrane

Page 3: The “brain” of the cell Large, spherical Contains DNA Enclosed in a double- layered nuclear membrane

•Ribosome production

•Consists RNA & Protein

•Consists of loose fibers composed of DNA & protein called chromosome

•Contains information for protein synthesis

Page 4: The “brain” of the cell Large, spherical Contains DNA Enclosed in a double- layered nuclear membrane

•Double lipid bilayer

•Protects the nucleus

•Contains nuclear pores

•Passing way between nucleus & cytoplasm

•Allows ribosome to exit nucleus

Page 5: The “brain” of the cell Large, spherical Contains DNA Enclosed in a double- layered nuclear membrane

•Ribosome are found in cytoplasm & ER membrane

•Composed of RNA & protein

•Help in the production of protein

Page 6: The “brain” of the cell Large, spherical Contains DNA Enclosed in a double- layered nuclear membrane

•Made up of a folded membrane

•Provides a tubular transport system inside the cell

Page 7: The “brain” of the cell Large, spherical Contains DNA Enclosed in a double- layered nuclear membrane

Rough ER:

•Has ribosome on surface

•Protein synthesis & transportation

Smooth ER:

•Does not have ribosome on surface

•Lipid synthesis

Page 8: The “brain” of the cell Large, spherical Contains DNA Enclosed in a double- layered nuclear membrane

•Energy source of the cell

•Contain cristae needed for aerobic respiration

•The more folds, the more reactions

Page 9: The “brain” of the cell Large, spherical Contains DNA Enclosed in a double- layered nuclear membrane

•Composed of flattened sacs

•Refines, packages, and delivers the cell products

Page 10: The “brain” of the cell Large, spherical Contains DNA Enclosed in a double- layered nuclear membrane

•Contains powerful enzymes to break up old cell components and bacteria

•“garbage disposals” of the cell

Page 11: The “brain” of the cell Large, spherical Contains DNA Enclosed in a double- layered nuclear membrane

•Contains enzymes that function in the synthesis of bile acids, breakdown of lipids, degradation of rare biochemicals, and detoxification, and detoxification of alcohol.

•Made up of 2 hollow cylinders called centrioles

•Chromosome distribution

Page 13: The “brain” of the cell Large, spherical Contains DNA Enclosed in a double- layered nuclear membrane

•Motile extensions from the cell

•Cilia is shorter than flagella

•Flagella helps sperm cells move

•“jelly stuff” inside the cell membrane

Page 15: The “brain” of the cell Large, spherical Contains DNA Enclosed in a double- layered nuclear membrane

•Selectively permeability

•Signal transduction

•Protects the cell and its organelles within

Page 16: The “brain” of the cell Large, spherical Contains DNA Enclosed in a double- layered nuclear membrane

•Plasma membrane

•Nucleus and nucleolus

•Mitochondria

•Ribosomes

•Endoplasmic reticulum

•Golgi apparatus

•Peroxisomes (the crystal in the electron micrograph is enclosed within a peroxisome)

•Microtubules

• Plant cells differ from animal cells in lacking:

•centrioles

•intermediate filaments
