CHAPTER : CELL STRUCTURE AND FUNCTION

LESSON # 1: CELL AND LIFE

OBJECTIVE:OBSERVE HOW DO THE

STRUCTURE AND PROCESSES OF A CELL

ENABLE IT TO SURVIVAL

The Cell theory






The Cell macromolecules






Nucleic acids

1. Contain genetic information.

2. Form when long chains of molecules called nucleotides join together.

3. The order of nucleotides in DNA(cell growth and reproduction) and RNA(proteins)






Proteins

1. Communication

2. transport

3. Chemical breakdown of substances

4. Structural support






Lipids

1. Energy storage

2. Protective membrane

3. communication






Carbohydreates

1. Energy storage

2. Structural support

3. communication


LESSON # 2: CELL

OBJECTIVE: OBSERVE HOW THE CELL DEVELOP

THEIR ACTIVITIES THROUGH ORGANELLES

Animal cell vs Plant cell


LESSON # 2: CELL

OBJECTIVE: DESCRIBE THE ORGANELLES¨

FUNCTION OF THE CELL

Cell organelles functions:

1. Cell membrane: Flexible covering that protects the inside of a cell from

the environment

2. Cell wall: Stiff structure outside the cell membrane

3. Cytoplasm: a fluid inside a cell that contains salt and other molecules

4. Nucleus: Directs cell activities

5. Chloroplast: Use light energy and make food and sugar

6. Vacuole : Stores food , water and waste

7. Lysosomes: digestive system of teh cell

8. Endoplasmic reticulum: It is a network for transportation of certain

substances in and out of the nucleus

9. Mitochondria: main energy source of the cell

10. Ribosomes : produce proteins


LESSON # 3 MOVING CELLULAR MATERIALS

OBJECTIVE: IDENTIFY HOW PARTICLES CAN

MOVE INTO AND OUT FROM THE CELL

Type of Transport:

1. Diffusion: movement of substances from an area of higher

concentration to an area of lower concentration. Diffusion continues

through membrane until the concentration of a substances is the same

on both sides of the membrane




MOVES INTO AND OUT FROM THE CELL

Type of Transport:

1. Osmosis: diffusion of water only through a membrane




MOVES INTO AND OUT FROM THE CELL

Active transport: Is the movement of substances through a cell membrane only by using the cell´s energy Passive transport: Is the movement of substances through a cell membrane without using the cell´s energy


LESSON # 4 CELLS AND ENERGY

OBJECTIVE: OBSERVE HOW PLANTS GET ENERGY

TO PRODUCE S OTHER GENETICS MATERIALS

Cellular respiration: Series of chemical reactions that convert the energy in food molecules into a usable form of energy ATP Types of cellular respiration: a- Glycolysis in Cytoplasm (Brake sugar into smaller particle and to produce small molecules,ATP) b- Reactions in Mitochondria (Convert oxygen and small molecules into energy,water and carbon dioxide)



OBJECTIVE:OBSERVE HOW PLANTS GET ENERGY


Cellular respiration: Series of chemical reactions that convert the energy in food molecules into a usable form of energy ATP Fermentation: Obtain energy without oxygen . Convert glucose and others carbohydrates into alcohol,organic acid and carbon dioxide . In which reaction does fermentation occurs?


LESSON # 4CELLS AND ENERGY



Cellular respiration: Series of

chemical reactions that convert the

energy in food molecules into a usable

form of energy ATP

Photosynthesis:

Convert light energy, water and

CO2 into glucose and oxygen





Cellular respiration formula

C6 H12O6 + 6O2 6CO2 + 6H20 + Energy

Photosynthesis

6CO2 + 6H2O C6H12O6 + 6O2
