cell structure 2
100
where all the DNA is stored in the cell
What is the nucleus
100
helps carry oxygen to the body
What is the blood cell
100
at what phase is the genetic material in the cell condenses to form chromosomes
What is prophase
100
how many cells are there in the human body
What is 100 trillion+ it varies from person to person
100
acts as a boundary layer that contains the cytoplasm
What is cell membrane
200
provides protection from physical injury, with the vacoule it provides skeletal support
What is cell wall
200
protects us from chemicals, infections, and UV radiation, and makes up the largest organ in the body
What is the skin cell
200
at what phase are the chromosomes align themselves along the cell spindle at the middle of the cell, when iit is ready to separate
What is metaphase
200
when a cell commits suicide because it has been infected, this happens to insure the proper development for the body,
What is apoptosis
200
stores water and chemicals, it produces turgor pressure against cell wall for support
What is the vacuole
300
forms splindle fibres to separate chromosomes during cell division
What is the centriole
300
a neuron that relays chemical signals that it received from stimuli or other neurons, they are often killed by serious head injuries
What is the brain cells
300
at what phase is the cell prepared to divide in two
What is the telophase
300
cells that never mulpitly
What is the brain cell, nerve cell
300
site of protein synthesis, and where RNA is translated into protein
What is the ribosome
400
stores chemicals and modifies them to make them functional
What is golgi apparatus
400
helps caryy information to the brain as electricity, it helps us feel and react to things such as hot surfaces
What is nerve cell
400
at what phase are the chromatids seperate and move to opposite sides of the cell
What is the anaphase
400
this can happen when cells begin to divide out of control
What is cancer
400
stores energy in the cell, has ATP
What is mitochondrion
500
breaks down molecules into smaller ones by adding water
What is the lysosome
500
abosrbs water and minerals for our body
What is the hair cell
500
DNA is copied and shared equally, the chromatids are seperated into two,
What is mitosis
500
the process where the cell goes through the process of cell growth and begins to mulpitly
What is the cell cycle
500
where DNA and proetins are packed together to form the genetic material of chromosomes
What is chromatin
