B1- Cell Biology Flashcards
what type of cell are bacteria
prokaryotic
five subcellular structures that both plant and animal cells have
nucleus, cytoplasm, cell membrane, mitochondria, ribosomes
where is the genetic material found in animal cells
the nucleus
3 things plant cells have that animal cells don’t
cell wall, chloroplasts, permanent vacuole
where is the genetic material found in bacterial cells
cytoplasm
which has higher resolution light or electron microscope
electron microscopes
what is cell differentiation
the process by which cells become specialized to perform specific functions in an organism
two ways sperm is adapted for swimming to an egg
tail to help swim, lots of mitochondria to give energy to swim
chromosomes
thread-like structures located inside the nucleus of animal and plant cells
cell cycle
a set of steps that take place in cell division
what do multicellular organisms use mitosis for
provides new cells for growth and for replacement of worn-out cells, such as skin cells
one way that embryonic stem cells could be used to cure diseases
could be used to replace faulty cells in sick people
why some people are against using embryos in stem cell research
because they think that they may be killing a human
diffusion
is the spreading out of particles from an area of higher concentration to an rea of lower concentration
how does temperature affect the rate of diffusion
higher the temperature the higher the diffusion rate
