3  Cell : a cell is a basic unit of structure and function of life. In other words, cells make up living things and carry out activities that keep a living thing alive.  Your body is made up of specialized cells which carry out the processes needed for life.

4  Genetic material ◦ Contains the material for life (DNA)  Cytoplasm fills cell interior – Liquid ◦ Contains organelles sugars, amino acids  Plasma membrane(aka. Cell Membrane) Encloses the cell – it is like the cells’ skin

7  Cytoplasm  Not an organelle, suspends the organelles  Cell Membrane  Nucleus  Mitochondria  Endoplasmic Reticulum (ER)  Golgi Bodies  Vacuoles

8  Gel-like substance which holds all the cell components together  Made mostly of water  Place where many chemical reactions occur

9  The flexible double-layered “skin” of the cell  Just like our skin holds us together, the cell membrane holds the cell and its components together  It also allows the movement of substances into and out of the cell.

10  Controls the cell – akin t our brains controlling us  Holds the genetic material (DNA) which is stored on Chromosomes  Directs activities of the cell  Usually one per cell, some cells have several (muscle) while other have none (Red Blood Cell)  Spherical in shape

11  DNA of eukaryotes is divided into linear chromosomes. ◦ Contains all the information needed for life (genes) ◦ We have 23 pairs = 46 totalTotal, half from mom and half from dad

12 " Powerhouse of the cell " – Uses Glucose to provide cells with energy (Cellular Respiration) Glucose + Oxygen  Carbon Dioxide + Water + Energy Cells that use a lot of energy have more Structure - outer and inner membranes

13 ◦ Network of transportation tubes which transport cellular substances around the cell (akin to a subway network transporting people from place to place)

14 ◦ _________________ ◦ Create and secrete mucus which is used as lining for the intestine and stomach

15  _________________  Contain unwanted substances for removal  Maintaining internal pressures (Plant)

17 Chloroplasts are larger and more complex than mitochondria Contain chlorophyll which gives plants their green colour and also allows them to absorb light to be used to create sugar in the process of photosynthesis

18  _________________ Carbon Dioxide + Water + Light Energy  Glucose (Sugar) + Oxygen Photosynthesis Intro Video

19  Within plant cells, photosynthesis takes place to produce glucose (sugar)  The sugar is then used within the mitochondria (cellular respiration) of both plants and animals  How do the animals obtain the glucose?

20 It’s a Cycle!! The products of photosynthesis are the reactants of cellular respiration The products of cellular respiration are Are the reactants of photosynthesis YOU CAN’T HAVE ONE WITHOUT THE OTHER!! Photosynthesis Glucose + Oxygen  Carbon Dioxide + Water + Energy Carbon Dioxide + Water + Light Energy  Glucose (Sugar) + Oxygen Cellular Respiration

21  Plant cells usually have one large vacuole  Maintains the cells pressure  keeps the plants stems and leaves firm  _________________
