The larger the cell the more
volume
demands placed on the cell structures
waste
Larger cells are less efficient in
moving materials across the cell membrane
consuming energy
Ratio of
Volume to surface area
surface area to volume
Volume determines...............
how quickly wastes are made
the speed of the cell
Surface area determines
how much food,oxygen, and water enter and how much waste will be released
As cell size increases, volume increases at a faster rate than surface area.
During asexual reproduction the cell copies DNA and replicates and then divides into 2
In asexual reproduction the offspring is
a combintation of the parents
identical to the parent
A single cell goes through binary fission
Multi cellular
hydra-budding
plants vegitative propagation
cell dna
Advantages of asexual reproduction include an easy survival strategy if conditions are right and require less time for more to survive
During sexual reproduction the egg and the sperm combine
Offspring inherit a combination of the parent's genetic info therefore the offspring is a genetic combinition of the parents
An advantage of sexual reproduction is
less time
more biodiversity
Disadvantages of sexual reproduction are
must find mate
requires more time for growth and development
genetic disorders
