Cell Structure & Function Cells and Heredity Chapter 1.2 (pgs 23-31) http://www.sciencedaily.com/releases/2011/09/110908124152.htm

Inside the Cell Humans are made up of several bodily systems (Respiratory, Nervous, Digestive) that utilize organs Cells have similar structures, called organelles.

Entering a Cell Animal cells have only a Cell Membrane, which allows materials in & out of the cell.

Entering a Cell Cells are held together with a Cell Wall Found only in plant cells Rigid layer made of cellulose

The Nucleus The “brain” of the cell Has a Nuclear Membrane Controls all aspects of the cell’s activity Has a Nuclear Membrane Protects the Nucleus just like the Cell Membrane.

Into the Cytoplasm The area inside the cell is called the Cytoplasm, which is constantly churning Contains many organelles.

Cell Wall Cell Membrane Nuclear Membrane The structure that allows materials In & Out of an animal cell is called… 1 Cell Wall 2 Cell Membrane 3 Nuclear Membrane

Mitochondria produce the energy a cell needs Oodles of Organelles Mitochondria produce the energy a cell needs Vacuoles are storage areas in the cell Lysosomes break down food and parts

The ER The Endoplasmic Reticulum is the passageway that materials travel along Ribosomes on the ER are protein factories, to build & repair cells Golgi Bodies package and ship materials to other parts of the cell.

This organelle is a storage space within a cell… 1 Golgi Body 2 Vacuole 3 Endoplasmic Reticulum 4 Mitochondria

This organelle is the passageway for materials within a cell… 1 Golgi Body 2 Ribosome 3 Endoplasmic Reticulum 4 Mitochondria
