Essential Question: How does photosynthesis the life processes of a cell?Science 7Next Science Test:The Cell and Cell Theory Unit TestWednesday, November 18Study guide is also posted onlineHomework: ScienceIt is recommended that you complete SLIDE 7 from your unit review slide presentation tonightCharacteristics of Living Things: VocabularyA living thing-- this is an individual example of a specific species of living thing.ORGANISM

Comparing Similarities Between Living Things

Characteristics of Living Things: VocabularyThere are seven characteristics that all living things share with one another:All living things RESPIRATEAll living things EXCRETE wasteAll living things require NUTRIENTSAll living things GROWAll living things REPRODUCEAll living things are SENSITIVE to their environmentAll living things MOVE

***Of course within any species, there are injuries or problems with the body that can cause one of these features to not work properly this does not mean that the organism isnt alive. For instance, a dog who has had its reproductive organs removed (spayed or neutered) is not suddenly a non-living thing

Introduction to Cells: VocabularyThis is the smallest individual part of an organism that can still be considered "alive". It is capable of carrying out all life functions that living things do (such as respirate, excrete, reproduce, etc.)

CELL

Introduction to Cells: VocabularyThis is a type of organism made of many cells working together. An example would be a human being

MULTICELLULAR ORGANISM

Introduction to Cells: VocabularyThis is a type of organism that is made of only a single cell. An example of this would be bacteria.

UNICELLULAR ORGANISM

Introduction to Cells: VocabularyThese are microscopic, single-celled organisms that live everywhere. Some types of these cause food to spoil; other types of these can make you become sick.

BACTERIA

The Organelles of a Cell: VocabularyThis is the gelatin-like liquid that makes up the majority of the cell.CYTOPLASM

This is the outer layer of a cell that separates and protects the cell from the environment around it.CELL MEMBRANE

This is the organelle in a eukaryotic cell which in which you would find the genetic material (DNA) for the cell.NUCLEUS

Cellular Processes: VocabularyThis cell process is when water seeps into and out of a cell through the cell membrane in order to maintain appropriate water levels within the cell.Osmosis

During osmosis, water moves from areas of _____ concentration of water, to areas of _____ concentration of water

HIGH CONCENTRATION TO LOW CONCENTRATION

Cellular Processes: VocabularyThis is a cellular process during which a cell oxygen is used to burn glucose, creating energy for the cell; this process takes place in the mitochondria.CELLULAR RESPIRATION

What materials are NEEDED for cellular respiration?GLUCOSE (SUGAR) AND OXYGEN

What materials are PRODUCED by cellular respiration?ENERGY, CARBON DIOXIDE, AND WATER

Todays Topic: How does photosynthesis support the life of a cell?Warm-Up Discussion/Brainstorm: You know that living things require oxygen in order to survive. But why do they need oxygen? What do they use it for?Photosynthesis: Basic Facts Photosynthesis only occurs in plant cells and SOME unicellular organisms

Photosynthesis uses the energy from sunlight to help make sugar for plants to use as foodFoldable: PhotosynthesisUse your chromebook to access the link listed for Photosynthesis foldableUse the materials provided to create a foldable for photosynthesis that will be kept in your notebookIf you need additional references to help you, check out pages C48 and C49 in the yellow textbookExit Ticket: Access the Exit Tickets page of DeBolts wikiClick on the link for todays exit ticketComplete the quiz before leaving className format:your period number, Last name, First name
