Energy How do living things get energy? Plants get _____ from the _______ while animals get _____ from other animals or plants. Indirect Grass uses sun to make their own food Direct Zebra eats grass D ct ire d In t c ire Dr. Binocs Photosynthesis Ted Ed Photosynthesis Lion eats zebra

Photosynthesis Autotrophs make their __________(ex. Plants make their own food through photosynthesis). Heterotrophs _______make their ______and therefore eat other organisms for energy. (Ex. Lion eating a zebra)

Photosynthesis The process by which a ____cell captures ______ in ______and uses it to ______. Nearly all living things obtain energy either __________ __ from the energy of sunlight captured during ________

Evidence for Photosynthesis 1. You exhaled Carbon Dioxide (CO 2) into the test tube which changed the color from ______ to _________ 2. I put a water plant in the test tube. This turned the color from ______ to _________. Plants use ________ and release __________ gas into the atmosphere. . What can you conclude from this? _______________________________________________________________

Photosynthesis During photosynthesis plants and some other organisms use _____________to convert _________and _____ into _______and ________ Photosynthesis takes place in two stages. Stage 1: Capturing the Sun’s Energy Stage 2: Using Energy to Make Food

Stage 1: Capturing the Sun’s Energy is captured in the plant’s ______ by ________ and uses to power the second stage of photosynthesis What is chlorophyll? Chlorophyll is the ______________ in chloroplasts. Chlorophyll is what makes chloroplasts and the plant’s leaves _______.

Stage 2: Using Energy to Make Food _______ _enters the plant through small openings on the undersides of the leaves called _______ The plants _____ absorb ____ from the soil and move up the plant to the leaves. Water and carbon dioxide move into the chloroplasts where they undergo chemical reactions powered from the energy captured in stage 1

Stage 2: Using Energy to Make Food ______ (O 2)is also produced which exits the leaf through the _______. These chemical reactions produce products such as a six carbon sugar called ______ (C 6 H 12 O 6). This is used for _______ to drive cell functions

Photosynthesis Equation The events of photosynthesis can be summarized in a chemical equation Products Reactants 1. 2. Dr. Bionics Photosynthesis 3. 4.

Cellular Respiration Equation Is this the photosynthesis equation? What do you notice about this equation? It’s the photosynthesis equation but ________ Plants make their own glucose from ________ Animals get glucose from _______ The oxygen comes from the __________ or _______ surrounding the organisms. What is the purpose of cellular respiration? * _______________________

Cellular Respiration The process of how cells get energy from __________. Cells break down simple food molecules like _____and release the _______ they contain. Both plant and animal cells continually respire.

What does the term respiration remind you of? Is cellular respiration the same thing as respiration like breathing? brain pop

Cellular Respiration Plant and animal cells can store energy just like you can store money in a bank. Carbohydrates are stored until cells are ready to “withdraw” it by breaking down the carbohydrate through respiration. Just like photosynthesis cellular respiration is a two -stage process.

Cellular Respiration: Stage 1 Molecules of ________ are broken down into smaller molecules inside the _________ of the cell. No _________ is involved yet Very _______amount of ________ is released. Lets Draw it!

Cellular Respiration: Stage 2 ___________are broken down even further inside the __________ of the cell. These chemical reactions need ________ and therefore release a _____________________are produced from this process and diffuse out of the cell. Lets Draw it!

What do you notice about the photosynthesis and respiration equations?

The Cell Cycle The cells in your body can ___________. This process of growth and division is called the __________ During the cell cycle a cell _____________________ and divides into two new cells called “daughter cells” There are three stages to the cell cycle; Interphase Mitosis Cytokinesis Youtube Cell Cycle Twig Cell Cycle

The Cell Cycle Not only does the cell divide but the cell’s ____ needs to divide so that each ________ has a copy. The DNA is the cells ___________ and it will condense into tightly coiled structures called ____________ Those chromosomes are found inside the __________ of the cell Gene DNA Chromosome

o Structure of DNA looks like a ___________. It is composed of sugar, phosphates and nitrogen bases ______ = Deoxyribose _________________ _= Adenine (A) Thymine (T) Guanine (G) Cytosine (C)

Why do cells need to divide? To ______________old damaged cells What happens when the cells stop dividing? That’s ___________! What happens when the cells wont stop dividing or they divide _________ What A is cancer? disease in which cells grow and divide _________, damaging the parts of the body around them. Ex. Weeds

How Cancer Begins Something damages a portion of the ____in a chromosome. The damage causes a change in the DNA which is called a ________. Cancer begins when ______________ cell cycle, causing cells to divide in an _______________

o So what is a tumor? A __________________that develops when cancerous cells divide and grow uncontrollable. So how do you treat cancer? ___________________________________________
