All About Cells
Organelles
Metabolism
Cell Cycle
A series of events that lead up to a cell's division and duplication.
Divisions of the Cell
Organelles are any of a number of organized or specialized structures within a cell.
Kinds of Cells
Cell Membranes
Transport
Passive
Active

Cellular Respiration
Metabolism consist of photosynthesis and cellular respiration
Photosynthesis
A way for certain organisms to obtain energy from organic molecules
This process takes place in the cell and tissues, in which carbon dioxide is released
Formula:
C6H12O6 + O2 6CO2 +6 H2O + Energy
Word Equation:
Glucose + Oxygen Carbon Dioxide + Energy/ATP
Photosynthesis is when you convert light energy to chemical energy, which are stored in the bonds of sugar.
Formula:
CO2 + H2O + Energy C6H12O6 + O2
Word Equation:
Carbon Dioxide + Water + Sun Glucose + Oxygen
Process of Photosynthesis
Mitosis
Mitosis is an asexual reproduction
The product of this process is two identical daughter cells
Process of Mitosis
Vocabulary
Labs
What are the Organelles jobs
Pictures
Vocabulary
The mitochondria is where cellular respiration takes place.
Pictures
Phases
G1- The growth phase.
S1- Synthesis, this is were everything inside the cell duplicates.
G2- Where the cell grows more.
G0 is where cells that do not grow or duplicate go.
Meiosis
Meiosis is sexual reproduction
The product of Meiosis is 4 Haploid cells
Pictures
Mitosis VS Meiosis
Pictures
Products
Mitosis- 2 identical daughter cells
Meiosis- 4 haploid cells not identical
Founder and Process of Meiosis

Plant Cell
Animal Cell
Eukaryotic VS Prokaryotic
Prokaryotic Cells
Pictures
Eukaryotic cells are organism that contain a nucleus and other structures encolsed within a membrane
Eukaryotic cells consist of memebrane bound oraganelles
There are two types of Eukaryotic cells- Animal and Plant cells
Prokaryotic Cells- Group of organisms whose cell lacks a membrane nucleus.
No membrane- bound organelles
Example of a Prokaryotic cell is a Bacteria
Process of Cellular Respiration
Mitosis VS Meiosis
There are two methods of cell division
There are 2 types of transports- Active and Passive
When something goes in and out of the cell without the use of Energy.
Pictures
Ex: Glucose entering the cell, diffusion, osmosis, and Facilitated Diffusion.
Labs
Active transport is when something goes in and out of the cell with the use of energy.
When a cell moves against its concentration gradient (from low to high)
The movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requires energy.
Ex: Uptake of glucose in the intestines in a human, uptake of mineral ions into root hair cell plants.
Pictures
Passive VS Active
Transport
Passive- No Energy
Active- Energy Required
A Cell Membrane is a semipermeable membrane surrounding the cytoplasm of the cell.
Pictures
Tonicity
-Tonicity is the ability to of a solution to cause a cell to gain or lose water
-A state of normal firmness or functional readiness of body tissues or organs; a condition of sustained partial contraction of resting or relaxed muscles

What is a Cell?
A cell is the smallest structural and functional unit of an organism.
Typically microscopic
