Nucleus• The cell nucleus is a
cellular organelle enclosed by a doubled-layered, porous membrane.
• Function:• Storage place for DNA.• Gives out orders to other
cell organelles.• It also holds chromatin,
another version of DNA.
It also holds the nucleolus which produces ribosomes to make protein.

Nuclear Envelope
• The nuclear envelope is a membrane that shields the nucleus.
• It contains pores so that cell products can move in and out of the cell.

Endopasmic Reticulum
• Rough Endoplasmic Reticulum produces and transports proteins.
• Smooth Endoplasmic Reticulum produces and transports lipids.

Golgi Apparatus
• An organelle that prepares cellular products for secretion.
• It “packages” the cellular products.

Mitochondria
• Organelle housing enzymes that catalyze reactions of aerobic respiration.
• This is the “energy source” of the cell.

Cytoplasm
• The contents of the cell, excluding the nucleus and cell membrane.
• Jelly-like substance.

Lysosomes
• Organelles that contains digestive enzymes.
• Acts like a garbage disposal in the cell.

Cell Membrane
• A protective bi-layered membrane that surrounds the whole cell.
• It is selectively permeable and it uses signal transduction to gain information about its surroundings.

Vacuoles
• Membranous cytoplasmic sac formed by enfolding of the cell membrane.

Cell Topic: Plant Cells
• Plant cells functions almost like animal cells.
• Plants cells contain an additional organelle called chloroplast to help with photosynthesis.

Cell Topic: Plant Cells
• In addition, they have a cell wall.
• The cell wall provides and maintains the shape of the cell and serves as the protective barrier.
• A plant cell is a prokaryotic cell.
