Falcon Focus WRITE QUESTION & ANSWER Identify the number of hydrogen atoms on the reactant side of the following equation: NaOH + CH3COOH  CH3COONa + H2O

What I will learn today? Objective: Essential question: Explain how cellular processes (including respiration, photosynthesis in plants, mitosis, and waste elimination) are essential to the survival of the organism Essential question: How are photosynthesis, respiration, and waste elimination necessary for cell survival?

Diffusion One way in which materials move across the cellular membrane Materials move from area of higher concentration to area of lower concentration

Osmosis The diffusion of water across the cellular membrane

PHOTOSYNTHESIS Plants use light energy (sunlight) to combine carbon dioxide and water to produce simple sugars (glucose). Plant cells also release oxygen gas. Photosynthesis occurs in the chloroplasts.

Let’s Write The Chemical Formula For Photosynthesis Carbon Dioxide + Water + Light ----> Sugar + Oxygen

RESPIRATION Plants and animals, break down glucose (sugars) into carbon dioxide and water and release energy. Respiration occurs in the mitochondria of cells.

Let’s Write The Chemical Formula For Respiration sugar + oxygen -> carbon dioxide + water + energy

WASTE ELIMINATION Cells eliminate waste products that could be harmful. The waste particles will move from a more concentrated area to a less concentrated area. Waste particles are stored in the Vacuole.

MITOSIS Cell reproduction is called mitosis and occurs in the nucleus of the cell. Mitosis enables a cell to make an exact copy of it. Mitosis is a process of cell division, which results in the production of two daughter cells from a single parent cell. The daughter cells are identical to one another and to the original parent cell. Mitosis is needed for growth, replacement, and Asexual reproduction. Video under MITOSIS- right click to view
