A bacterium

A cell possesses ribosomes a plasma membrane the cell wall and other parts it could not be

A cell from a mouse

Which of the following consist of prokaryotic cells

Bacteria and Archaea

If a celles chromatin were damaged the cell would

Go out of control

A researcher made an interesting observation about protein made by the rough ER and eventually used to build a cells plasma membrane. The protein in the membrane was actually slightly different from the protein made in the ER. the protein was probably changed in the

Golgi apparatus

Processes packages and stores the fats and proteins produced by the ER

Golgi body

What two things make up the cell membrane

Phospholipids and embedded proteins

The electron microscope has been particularly useful in studying prokaryotes because

Prokaryotes are so small

What surrounds all cells

Plasma membrane

Structures found only in plant cells chloroplasts are one type

Plastids

Control cell processes and contains genetic hereditary information

Nucleus

Control center of the cell contains nucleoli and DNA

Nucleus

A mutant plant cell unable to manufacture cellulose would be unable to

Build a cell wall

At what level of organization does life begin

Cell

Also called the plasma membrane

Cell membrane

Semi permeable barrier made of two layers of phospholipids

Cell membrane

Thin flexible barrier around the cell controls what enters and leaves the cell

Cell membrane

Mostly made of cellulose this encases or surrounds plant cells and give them their characteristic shapes

Cell wall

Not found in animal cells used for support and protection of the cell found outside the cell membrane

Cell wall

What are the structures present in plant cells but lacking in animal cells

Cell wall chloroplasts

Assists in cell reproduction in animal cells

Centrioles

Only found in animal cells form spindle fibers during cell division

Centrioles

Centrioles are found at the center of the

Centrosome

Sites for photosynthesis found only in plant cells contain chlorophyll

Chloroplast

Contain chlorophyll and absorb light energy for photosynthesis

Chloroplasts

Location where photosynthesis occurs

Chloroplasts

Uncoiled DNA coils into chromosomes during cell division

Chromatin

Locomotive structures made up of microtubules

Cilia and flagella

Material inside the cell membrane but not including the nucleus

Cytoplasm

Support the shape of an entire cell

Cytoplasm

Watery substance that fills the interior of cells and suspends organelles

Cytoplasm

Gives the cell support skeleton of the cell

Cytoskeleton

The maximum size of a cell is limited by

It's need for enough surface area for exchange with its environment

If the nucleus is a cells control center and chloroplasts it's solar collectors which of the following might be called the cells combination food processor and garbage disposal

Lysosome

Bags of enzymes used to digest particles and bacteria garbageman of the cell they work in conjunction with vacuoles

Lysosomes

Filled with enzymes and digests old organelles removes junk

Lysosomes

Involved in muscle contraction in larger organisms

Microfilament

Make up Cillia flagella and centrioles

Microtubules

Supports the cell and also is involved in cell movement

Microtubules

The internal skeleton of a cell is composed of

Microtubules intermediate filaments and microfilaments

Creates energy in the cell powerhouse of the cell

Mitochondria

Powerhouse of the cell site of ATP production

Mitochondria

Organelles involved in energy conversion are the

Mitochondria and chloroplasts

Membrane around the nucleus

Nuclear envelope

Location where ribosomes are formed

Nucleolus

Makes ribosomes

Nucleolus

Make proteins and can be free or on the endoplasmic reticulum

Ribosomes

Membranous structure that synthesizes proteins

Ribosomes

Site of protein synthesis found in cytoplasm and on rough ER

Ribosomes

Acts as a transport system for newly formed proteins

Rough endoplasmic reticulum

External surface is studded with ribosomes

Rough endoplasmic reticulum

You would expect a self with an extensive Golgi apparatus to

Secrete a lot of material

Membranous structure that synthesizes fats

Smooth endoplasmic reticulum

What does semi permeable mean

Somethings can get through it

Cellular metabolism is

The chemical activity of a cell

Which of the following would not be considered a part of a cells cytoplasm

The nucleus

To enter or leave a cell substances must pass through

The plasma membrane

Responsible for storage in the cell

Vacuole

Storage sacks plant cells have a single large one animal cells have many smaller ones

Vacuole

Formed from a piece of membrane breaking loose from cell membrane store substances

Vacuoles
