Essential Question: How do key organelles affect the life processes of a plant cell? Science 7

Next Science Test: “The Cell and Cell Theory” Unit Test Wednesday, November 18 Study guide is also posted online

Homework: Science It is recommended that you complete “SLIDE 8” from your unit review slide presentation tonight

Characteristics of Living Things: Vocabulary A living thing-- this is an individual example of a specific species of living thing. ORGANISM

Comparing Similarities Between Living Things

Characteristics of Living Things: Vocabulary There are seven characteristics that all living things share with one another: All living things RESPIRATE All living things EXCRETE waste All living things require NUTRIENTS All living things GROW All living things REPRODUCE All living things are SENSITIVE to their environment All 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 isn’t “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: Vocabulary This 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: Vocabulary This is a type of organism made of many cells working together. An example would be a human being MULTICELLULAR ORGANISM

Introduction to Cells: Vocabulary This 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: Vocabulary These 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: Vocabulary This 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: Vocabulary This 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: Vocabulary This 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

Cellular Processes: Vocabulary This is a process in which plant cells uses the convert the energy from sunlight into glucose molecules in order to provide the plant cell with an energy source. Inside the cell, this process takes place in the chloroplast. PHOTOSYNTHESIS What materials are NEEDED for photosynthesis? CARBON DIOXIDE, WATER, SUNLIGHT What materials are PRODUCED by photosynthesis? GLUCOSE, OXYGEN

Today’s Topic: How do the different organelles of a plant cell support the life processes of a cell?

Plant Cells: Basic Facts Go to “What did we do today in Science?” on my wiki to view microscopic images of plant cells Notice that plant cells have a somewhat rectangular shape Also notice that plant cells have many green circles floating around inside– these are the chloroplasts, responsible for photosynthesis
