Living Organisms
What are the characteristics of living things? (name 4)
Use energy (nutrition), respond to stimuli, reproduce, grow/develop, produce waste, made of cells
Which power level should you use when first viewing a specimen under a microscope?
Low power (40x magnification)
Having one cell
Unicellular
This system gets rid of waste materials in your body
Excretory system
What is the difference between osmosis and diffusion
Diffusion is the movement of any particles from an area of high to low concentration. Osmosis is specific to the movement of water.
Give an example of how living things carry out the same life processes (function), but have different structures.
Where should your hands be when carrying a microscope?
Arm and base
Is the powerhouse of the cell and makes ATP (energy)
Mitocondria
Body system that includes cells that send and receive signals throughout the body. This system also helps us respond to stimuli.
Nervous System
This organelle synthesizes and packages proteins and fats
Endoplasmic reticulum
Groups of specialized tissues working together to make a system
Organs
The part of the microscope that you look through.
Eyepiece or Ocular Lens
Holds the genetic material and is the control center of the cell
Nucleus
The system that is responsible for moving blood throughout the body
Circulatory system
A young person is having pain in their joints as they are getting taller (often known as growing pains). This happens because growth plates of bones are developing quicker than the body can adjust. What body system does this most likely affect?
Skeletal system
The basic unit of all life
Cells
Plant cells have this, animal cells do not
What are chloroplasts and cell walls?
Act like a door into or out of the cell
Cell membrane
The skeletal system
What process do chloroplasts carry out in plant cells?
Photosynthesis
Organism made of many different types of cells that do different jobs
Multicellular organism
What are the 3 keys points of Cell Theory?
All living things are composed of one or more cells
Cells are the basic unit of structure and function in all organism
All cells come from other cells
When waste products have a high concentration in the cytoplasm of a cell and a low concentration outside the cell, they can leave the cell by
Diffusion
This system is responsible for taking nutrients from food.
Digestive system
Describe how two different systems work together to help someone go on a walk
Circulatory These systems could all work
muscular
skeletal
nervous
