organelles
which organelle is the control center for the cell
nucleus
kingdom of large, blocky cells that perform photosynthesis
plantae
when is the DNA of the cell duplicated?
interphase
what is the theory called that living cells come from non-living matter?
spontaneous generation
what do you call a cell involved in sexual reproduction?
gamete
an organelle in animal cells but not in plant cells
centriole
kingdom of single celled eukaryotes
protista
in the cell cycle, when is the DNA in chromatin form?
interphase (also the start of prophase and the end of telophase)
what structure builds ribosomes in a cell?
nucleuolus
what type of solution will cause cells to shrivel up?
hypertonic
an organelle that is used as a surface for ribosomes
Which kingdoms are prokaryota?
bacteria, archaea
what is the difference between a sister chromatid and a daughter chromosome?
sister chromatid is half a chromosome when they are attached. Once they separate in anaphase, they are daughter chromosomes
which two parts of the cell cycle are considered "cell division"?
mitosis and cytokinesis
give an example of cells dividing for maintenance or repair
many answers: skin cells repairing / replacing old skin, etc.
These two organelles are in plant cells but not in animal cells
cell wall and chloroplast
give three differences between prokaryota and eukaryota
size (pro are much smaller), nucleus (euk has, pro doesn't), organelles (pro doesn't have, euk does)
name three things that occur in prophase
chromatin winds up into chromosomes, nuclear envelope disappears, spindle fibers form
what do spindle fibers do?
they pull on chromosomes to move them during mitosis
What is the male gamete for flowering plants?
pollen
What is the word equation for cellular respiration?
oxygen + glucose --> carbon dioxide + water + energy
name every kingdom and give one example of an organism from each kingdom (except the last kingdom we covered)
examples
what is the correct REVERSE order of the cell cycle, starting with cytokinesis?
cytokinesis, telophase, anaphase, metaphase, (prometaphase - optional), prophase, interphase
what is the difference between chromatin and chromosomes?
chromatin is a stringy, unwound version of DNA when the cell is not dividing. Chromosomes are coiled up / condensed versions of DNA that are easier to move during cell division
explain what happens to cells that are placed in a hypotonic solution (what does hypotonic mean, which way does water move, what does it do to the cell)
a hypotonic solution has a lower solute concentration than the cell. Water will enter the cell, causing it to swell and possible burst
