Cells- Biology

Tiny structure that performs a specialized function (or job) in the cell

Holds and protects the genetic information of the cell.

WHere proteins are made

Controls what enters and leaves the cell

Provides added structure and support to plant cells. Found outside the cell membrane.

Pathway for proteins

Modifies, sorts, packages and ships out proteins to where they are needed.

Contains digestive enzymes to break down old cell parts/waste.

Site of photosynthesis. Uses the suns energy to make food energy (glucose).

Site of cellular respiration. Uses food energy (glucose) to make usable energy (ATP)

Storage area for water and nutrients

Framework of filaments and fibers that supports the cell structure.

Long whip-like tail tht helps with movement.

Many small hairs that helps with movement.

Helps with cell division

What are 3 organelle plants have that animal cells s=dont have?

What are 3 organelles animals have that plant cells do not.

Do plant cells have mitochondria, chloroplasts, both, or neither?

Do animal cells have mitochondria, chloroplasts, both, or neither?

What is the heirarchy of an organism (beginning with atoms)?

What is the basic unit of life?

These three statements make up the ________ ___________. 1. All living things are made up of cells. 2. Cells are the basic structure and function of an organism. 3. ll cells come from preexisting cells.

What are 4 organelles ALL cells have?

Very small cells without a nucleus and membrane-bound organelles.

Larger cells with a nucleus and membrane bound organelles.

What is the only example of a prokaryote?

Microscope that uses light and two separate lenses to magnify a very thing image. Can magnify up to 2000x (our only go up to 400x).

Microscope that uses light and binocular lenses (2 eyepieces) to magnify a larger object. Can magnify up to 50x

Image in inverted (upside down and backwards) when using this microscope

How is total magnification determined?

If the ocular lens is 10x and the objective lens is on 4x, what is the total magnification?

Area seen when looking through the microscope

What happens to the field of view as you switch to a higher power?

On which power is you image smallest but field of view largest?

Microscope that uses electrons to show the surface of an object (magnifies up to 100,000x)

Microscope that shoots electrons through a thin object so you can see the inside (magnifies up to 200,000x)

What si a problem with using the electron microscope?

Larger knob on the side of the microscope that can only be used with scanning and low powers.

Smaller knob on the side of the microscope that is used mostly on high power.

Controls the amount of light shining on an object.

Eyepiece (10x) lens you look through.

Where the objective lenses are attached. Rotates to change objective lenses.

Where your bottom hand should be when carrying a microscope.

The part your other hand should hold while carrying a microscope (not the base)

3-4 lenses with different magnifications that can be changed to see more or less of your specimen.

Where the specimen/slide is places for viewing.

Put the following organisms in order from more primitive to more recent: aerobic prokaryotes, anaerobic prokaryotes, eukaryotes

Theory that eukaryotic celsl formed from smaller prokaryotes moving inside the larger prokaryotes and they formed a beneficial relationship with one another.

Wht do mitochondria and chloroplasts both contain that helps to support the Endosymbiotic Theory.

Without oxygen

With oxygen.

Is the picture an animal or plant cell and how do you know?
