Labeling a Cell
Microscopes
100
Living things must be made of at least one or more ________. They can be unicellular or multicellular.
Cells
100
Plant cells are usually shaped like a _________.
rectangle/box.
100
The control center of the cell that holds DNA.
Nucleus
100
Identify structure A.
Cell membrane
100
Why do scientists use microscopes?
Look at specimen that are too small for our eyes to see.
200
When living things make their own food, consume other things or break down dead materials, they need and use _____________.
Energy
200
Why does a plant cell have a fixed shape and an animal cell does not?
Cell Wall gives support and structure.
200
Makes food for the plant cell and absorbs sunlight to carry out photosynthesis.
Chloroplast
200
Identify structure B. 
Nucleus
200
Why do scientists use different magnifications for different substances?
They are different sizes and some of their cells are much smaller than others (example: cheek cells are smaller than onion cells.)
300
When living things increase in size, mature over time and have a life span, they ______________ and _________.
Grow and Develop
300
Which of the following structures is found in both plant and animal cells?
a. Mitochondria.
b. Cell wall.
c. Chloroplast.
A. Mitochondria
300
Stores food, water and waste in the cell and is much larger in the plant cell.
Vacuole
300
Identify structure C.
Cytoplasm
300
Place the substances (cells) in order from smallest to largest. 
C, B, A
400
Living things produce offspring through asexual or sexual ___________________.
Reproduction
400
___________ is the part of the plant cell that makes the process of photosynthesis possible.
a. Vacuole.
b. Cyotplasm.
c. Chloroplast.
c. Chloroplast
400
Controls what goes in and out of the cell.
Cell Membrane
400
Identify the green structures.
Chloroplasts
400
Living or nonliving? What characteristic do you see? 
Living- Plant cells that have cell walls and chloroplasts to carry out photosynthesis.
500
Living things have a genetic code and pass down traits to the next generation through ____________ in the nuclei of their cells.
DNA
500
True or False: Plant cells have larger vacuoles than animal cells.
TRUE! The vacuole takes up a large space in the plant cell for food, water and waste storage.
500
A gel-like fluid that supports the cell organelles and holds them in place.
Cytoplasm
500
What surrounds this type of cell?
Cell Wall
500
Living or nonliving? 
No cells are present therefore they don't have body systems to maintain a stable internal environment.
