Row 1, Col 1

Diffusion is the movement of particles

from a ___________ concentration

to a _________ concentration.

high, lower

1,2

Cell membrane

What protects and allows material in and out of a cell?

1,3

All living things are made of cellsOR

Cells are the smallest unit of lifeOR

All cells come from preexisting cells

Name one part of the cell theory.

1,4

Asexual reproduction

mitosis

What type of reproduction do cells go through?

What is the special name given for this type of

reproduction?

2,1

waterlowhigh

Osmosis is the movement of __________

from an area of __________ particle

concentration to an area of

_________ particle concentration.

2,2

Plant, chloroplasts

__________ cells have __________ which use photosynthesis to create

food for the cell/organism.

2,3

Name one part of the cell theory (not already mentioned).

All living things are made of cellsOR

Cells are the smallest unit of lifeOR

All cells come from preexisting cells

2,4

What happens in stage 2 of mitosis?

Nuclear membrane thins out,Chromatin gathers together

To form chromosomes( X-shaped structures appear)

3,1

Permeable lets some things through, impermeable does not

What is the difference between a permeable membrane and an

impermeable membrane?

3,2

What organelle provides

energy for the cell?

mitochondria

3,3

All living things are made of cellsOR

Cells are the smallest unit of lifeOR

All cells come from preexisting cells

Name one part of the cell theory (not already mentioned).

3,4

What happens in stage 3 of mitosis?

Chromosomes line up in center of cell

4,1

equal

Nature likes things to be __________. This is why there is movement such as diffusion & osmosis.

4,2

Golgi body/golgi apparatus

The ________ acts like a post office

and packages materials to move around

the cell or out of the cell.

4,3

Answers will vary…Allows us to see organisms not previously known

Can use to learn about/prevent diseasesUse to develop medicines

Can use to study complex and simple organisms

Why is the discovery of cells important to humans?

4,4

What happens in stages 4 and 5 of mitosis?

4 chromosomes & other organelles separate to opposite

Ends of cell

5 cell pinches into two new cells called daughter cells

5,1

To get the things the cell needsTo perform all functions of

Life and to get rid of things itDoesn’t need; to maintain

Equilibrium/equality

Explain why a cell needs to have

a semi permeable membrane.

5,2

Smooth does not have ribosomes

Rough has ribosomes, which make proteins

What are the 2 types of endoplasmic reticulum?

How are they different?

5,3

What evidence supports the idea that cells are the smallest unit of life?

All organelles are made of “molecules” of materials (matter) that are non-living. If a cell is broken down into

parts, the parts are considered non-living.

5,4

Why is it necessary that 2 identical cells are produced in mitosis?

Insures each cell has all necessary parts & information;

Easier than sexual reproduction (no males/females, sperm/egg)

Faster than sexual reproduction
