I. Organ Systems – (Notebook pages 1-3)
 Organs working together to perform a set of related tasks
 An entire living thing that carries out all the basic life functions
 A group of similar tissues performing a job
 The basic unit of structure and function of all living things
 A group of similar cells doing the same job
 List the levels of organization in their correct order, from simplest to most
complex:
 Name the two types of cells:
 Xylem, Phloem, and blood are all examples of:
 Leaf, flower, heart, liver and bladder are all examples of:
 Plant and Human are both examples of:
 Photosynthesis, storage, transport and hormones are all functions of:
 Anchorage, absorption, storage and transport are all functions of:
 What two systems must be working together to:
o Protect and support the body while allowing it to move.
o Receive and break down food while carrying needed substances to the
cells of the body.
o Carry needed substances to the cells of the body while producing chemical
messengers.
o Enables the body to move while collecting and removing waste products
from the body.
 Identify each of the following images as: Cell, Tissue, Organ or Organ System
 Which diagram above represents an organ system of a plant?
 Which diagram above represents a cell in a plant?

 What are the 4 different classifications of bone:
o
- radius, ulna, humerus & femur
o
- cranium, pelvic girdle
o
- fingers & toes (phalanges)

o
o
-
 The average adult human skeleton has how many bones?
 The job of this tissue is to cushion the bones from sudden jolts, provide a
slippery surface between the bones and repair broken areas:
 Define:
o Ossified –
o Joint –
o Ligament –
o Tendon –
 This type of joint allows for no movement at all:
 This type of joint allows for the greatest range of movement:
 This type of joint allows only back and forth movement:
 This type of joint allows one bone to rotate around another:
 Name each of the following types of joints:
(Shoulder)
