Cell membrane Identify cell structures depicted in diagrams and electron micrographs
How do we define Living? The following characteristics are used to define living things: 1. Living things are organized
Specialized for specific functions Have various levels organs/tissues/cells Cells are the smallest structural unit of life Cells are made up of molecules such as proteins, carbohydrates and fats
How do we define Living? 2. Living things need food or energy from the environment Animals obtains materials and energy when
they eat food Plants use CO2, water and solar energy to make their food, through the process of photosynthesis Nutrient molecules can be broken down into
parts and products through a series of chemical reactions. Some of these molecules will be broken down completely to provide energy for these chemical reactions. Metabolism is all the chemical reaction that
How do we define Living? 3. Living things keep a steady internal environment despite changes in the external environment. Example blood pressure, body temperature
Homeostasis helps maintain a constant internal environment despite changes in the external environment How do we define Living?
4. Living things respond to stimuli, both internal and external. An organisms behavior may be dictated by how it responds to its external environment Example movement towards light
How do we define Living? 5. Living things reproduce offspring, and offspring generally resemble parents. Asexual organisms divides, so offspring have
the same genes as parents (identical) Sexual each parent contributes half of the genes (variation) How do we define Living?
6. Living things grow and develop Changes occur during the lifecycle Different stages from fertilization to death Growth increase in size and number of cells Development stages that occur between
fertilization and death. How do we define Living? 7. Living things adapt to different environments and conditions.
May adapt to become suited to a particular way of life The Cell There are two types of cells:
1. Prokaryotic no nucleus or membrane-bound organelles Example bacteria 2. Eukaryotic has a nucleus and membrane-bound organelles
Example mammals Chromosomes Location in Cell Nucleus
Function Contains genetic information that regulates cell function Contains DNA and protein
Nucleolus Location in Cell Nucleus
Function Makes a chemical messenger, called mRNA. Carries the genetic information from the nucleus to ribosomes
Nuclear Membrane (Envelope) Location in Cell Nucleus Function
Separates the genetic information from the cytoplasm. Functions as a barrier Ribosomes
Location in Cell Cytoplasm Function Site of protein synthesis
Receives information from the nucleus to order the joining of amino acids into proteins. Endoplasmic Reticulum Location in Cell
Cytoplasm Function Transports various large molecules that are synthesized within the cytoplasm
Rough endoplasmic reticulum contains ribosomes that synthesize proteins. While the smooth endoplasmic reticulum does not contain ribosomes.
Mitochondria Location in Cell Cytoplasm Function
Converts energy Is involved in aerobic cellular respiration Formula for cellular respiration Golgi Body (Apparatus)
Location in Cell Cytoplasm Function Processes, packages and secretes various
proteins. Releases fluids through cell membrane by exocytosis. Lysosome
Location in Cell Cytoplasm Function Contains enzymes that digest things taken into
the cell. Is capable of destroying the cell Chloroplasts Location in cell
Cytoplasm Function Specializes in photosynthesis in plant cells
Microfilaments Location in cell Cytoskeleton Function
Provides shape and movement for cells. Are found in muscle cells Microtubules Location in cell
Cytoskeleton Function Are cylinders of protein found in cytoplasm, cilia and flagella
Help maintain shape and act as a track along which cell organelles can move.
