Bio
A cell has mitochondria ribosomes smooth ER and other parts based on this information it could not be
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
