Cells need energy!!!! Growing, moving, and functions that happen in the cell use energy A cell could NOT survive for long if it did not have the energy for all of the functions it does Pg. 68

Cells Get Energy from Food! The cells of all living things need chemical energy. Food contains chemical energy When cells break down food, the energy of the chemical bonds in food is released This energy can either be used or stored by the cell Pg. 69

Cells Get Energy from Food! Pg. 69 Living things get food in different ways and can be grouped based on how they get food Producer Consumer Make their own food Most use energy from the sun They use most of the food they produce for energy and store the rest in their bodies (fruits, roots, etc.) Eat other organisms May eat producers OR other consumers Decomposers are also consumers: they break down dead organisms or wastes Fungi and many bacteria are decomposers

How do plant cells make food? Pg. 70 Nearly ALL life on Earth gets energy from the sun Plants get it directly Animals get it indirectly by eating plants In a process called photosynthesis plants use energy from sunlight, carbon dioxide, and water to make sugars and oxygen

How do plant cells make food? Pg. 71 Photosynthesis occurs in chloroplasts Not found in animal or fungi cells Contain a green pigment called chlorophyll, which captures energy from sunlight This energy (sunlight) is used to combine carbon dioxide and water, which forms sugar glucose and oxygen gas Glucose-sugar that stores chemical energy Stored as starch in roots and stems

The energy flow of life occurs because of plants The energy flow of life occurs because of plants. Plants harness the energy from the sun, and pass it on to all other life forms. Copyright © 2010 Ryan P. Murphy

Plants can get their energy from the sun by just sitting there, we have to go search for it, hunt, etc. We didn’t we evolve to be green and get our energy from the sun. Why aren’t we green? Copyright © 2010 Ryan P. Murphy

Answer! Copyright © 2010 Ryan P. Murphy

Answer! Because photosynthesis only produces a small amount of energy. Copyright © 2010 Ryan P. Murphy

Answer! Because photosynthesis only produces a small amount of energy. We need lots of sugar to run, jump, and live our very busy and active lives. Copyright © 2010 Ryan P. Murphy

Mighty Mitochondria!! Pg. 72-73 The process of breading down food is called cellular respiration Takes place in MITOCHONDRIA of eukaryotic cells Takes place in CYTOPLASM of prokaryotic cells Starting materials are glucose and oxygen Products of cellular respiration are chemical energy, carbon dioxide and water

Merry-Go-Round! Photosynthesis and Cellular Respiration are connected! Most of the oxygen in the atmosphere was made during photosynthesis Nearly all organisms use that oxygen during cellular respiration They produce carbon dioxide and release it into the environment so plants can use it to make sugars

Photosynthesis provides the sugar (carbon based) so animals can use that sugar and through cellular respiration make energy. Copyright © 2010 Ryan P. Murphy
