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.
