Living Organisms Common Assessment Study Guide
LT 1: I can recognize that most organisms are unicellular and some are multicellular.
Label each of the pictures or organisms below as Unicellular (U) or Multicellular (M).
1.
4.
U

7. The basic units of life are called
M
U
3.
6.
Cells_.
Circle all answers that apply.
8. Most organisms on Earth are:
A. multicellular.
B. unicellular.
C. bacteria.
D. animals.
9. Characteristics of all organisms include:
A. All organisms are made of cells.
B. All organisms must breathe oxygen to survive.
C. All organisms must be able to reproduce and grow.
D. All organisms must consume other organisms to survive.
E. All organisms must be able to move.
F. All organisms are made of common elements of life.
M
10. A television uses energy and responds to certain stimuli, such as commands from its user. The camera is
not considered a living thing. List and justify at least 2 characteristics of living things that show a camera is
not living.
-A television/camera is not made of cells, and all living things are made of cells.
-A television/camera cannot get bigger or change, and all living things can grow and develop.
-A television/camera cannot make more of itself, and all living things can reproduce.
-A television/camera is not made mostly of the basic elements of life, and all living things are made of
Carbon, Oxygen, Hydrogen, and Nitrogen
LT2: I can identify examples of unicellular and multicellular organisms
Using the following list of groups of organisms, match the description with the organism.
BACTERIA
PLANT
ANIMAL
FUNGUS
Organism
Description
11. Animal
eukaryote, multicellular, heterotrophs, some have complex
systems made of tissues and organs
12 .bacteria
prokaryote, unicellular, reproduce asexually
13. fungus
eukaryote, multicellular or unicellular, heterotrophs, includes molds and
mushrooms
14.Plant
eukaryote, multicellular, uses photosynthesis, and some use a system of
vascular tubes to transport water and nutrients
15. Pick one organism you identified above and describe how you made your decision.
-An animal is made of many complex cells, and must eat other organisms to survive.
-A bacteria is made of individual simple cells, and can reproduce on its own.
-A fungus can be made of either one or many complex cells with cell walls, and must consume other organisms
for energy
--A plant is made of many complex cells, can absorb the suns energy to synthesis glucose from water and
carbon dioxide, and most have transport tubes to move water and nutrients.
LT 3: I can recognize that most plants and animals require food and oxygen.
16. List the 4 basic needs of living things:
1. Water
2.Food/energy
3.living space
4.stable internal conditions
17. How does a raccoon meet at least 2 of it needs for survival?
-A raccoon would find a pond, lake or stream for water
-A raccoon is an opportunistic eater, so eats a variety of foods in both the forest and suburban areas
-A raccoon will make a nest where it can find space: brush pile, tree cavity, log, etc
-A raccoon is warm-blooded, so can keep its temperature stable, and cues its body with hunger, thirst, and
panting.
LT 4: I can identify and contrast the structures of plans and animals that serve similar functions.
What structures do vascular plants and humans use to take in energy, exchange gases, take in water, and
move nutrients and water.
18.
Structures
Function
Humans
Plants
A human eats food and digests it
A plant absorbs sun energy with its
with its digestive system
chloroplasts/chlorophyll and uses
this
energy to make glucose and
Take in energy
oxygen from water and carbon
dioxide through photosynthesis
Exchange gases
Take in water
Move nutrients and water
A human breathes in oxygen and
out carbon dioxide through its
nose and mouth, using its
respiratory system.
A plant takes in Carbon dioxide
and releases oxygen through its
stomata/stoma, mostly on the
undersides of its leaves.
A human takes in water by mouth
and uses its digestive system to
start the process of distributing it
to the rest of the body
Plants take in water through their
roots and transport it to other
places via vascular tubes
A human moves water and
nutrients in the blood through the
circulatory system.
A vascular plant has vascular
tubes, xylem and phloem, through
which water, glucose, and
nutrients move.
LT5: I can describe how plants use energy from the sun to produce food and oxygen through photosynthesis.
19. Label each line as it relates to photosynthesis. Be sure to pay attention to the direction of the arrows!
