1. Life Science Unit 1 Chapter 3 Lesson 2 Cell Structure

2. Parts of a Cell Cell Wall- The outermost layer of cellulose that gives plant cells added support and strength Cell Wall- The outermost layer of cellulose that gives plant cells added support and strength –Animals do not have cell walls

3. Parts of a Cell Cell Membrane- a flexible, thin protective layer around a cell Cell Membrane- a flexible, thin protective layer around a cell – it helps determine what goes in and what comes out –The outer layer of an animal cell –The second layer in on a plant cell

4. Parts of a Cell Cytoplasm- A liquid that surrounds everything in a cell Cytoplasm- A liquid that surrounds everything in a cell Organelles- tiny structures inside a cell that perform a function for the cell Organelles- tiny structures inside a cell that perform a function for the cell –They “hangout” in the cytoplasm

5. Parts of a Cell Nucleus- the cell’s control center Nucleus- the cell’s control center –Stores genetic information –Control’s the cells functions –“The Brain” of the cell

6. Parts of a Cell Nuclear Membrane- The membrane around the nucleus Nuclear Membrane- The membrane around the nucleus –Lets things in and out of nucleus

7. Parts of a Cell Chromosomes- structures that directs cell growth and reproduction, and holds the genetic information that is passes on to new cells Chromosomes- structures that directs cell growth and reproduction, and holds the genetic information that is passes on to new cells

8. Parts of a Cell Mitochondria- organelles that produce energy for the cell Mitochondria- organelles that produce energy for the cell Endoplasmic Reticulum- The cells transportation system Endoplasmic Reticulum- The cells transportation system Ribosome- tiny organelles that produce protein for the cells Ribosome- tiny organelles that produce protein for the cells

9. Parts of a Cell Lysosomes- recycle worn out cell organelles and metabolized materials for the body to reuse Lysosomes- recycle worn out cell organelles and metabolized materials for the body to reuse Golgi Apparatus- modifies and transport proteins and liquids Golgi Apparatus- modifies and transport proteins and liquids Vacuoles- organelles that store water, food and other materials the cells need Vacuoles- organelles that store water, food and other materials the cells need

10. Parts of a Cell Chloroplasts- metabolic centers that contain chlorophyll Chloroplasts- metabolic centers that contain chlorophyll –Only in plant cells
