Cell Structure & Function
Cells and Heredity Chapter 1.2 (pgs )
2
Inside the Cell Humans are made up of several bodily systems (Respiratory, Nervous, Digestive) that utilize organs Cells have similar structures, called organelles.
3
Entering a Cell Animal cells have only a Cell Membrane, which allows materials in & out of the cell.
4
Entering a Cell Cells are held together with a Cell Wall
Found only in plant cells Rigid layer made of cellulose
5
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.
6
Into the Cytoplasm The area inside the cell is called the Cytoplasm, which is constantly churning Contains many organelles.
7
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
8
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
9
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.
