|
explain cell division
|
mitosis is asexual reproduction involving 1 parent involving a series of steps
|
|
|
what are the steps of mitosis
|
interphase prophase
metaphase anaphase telephase |
|
|
explain the process of photosynthesis
|
carbon dixoide, water and energy from the sunlight forms glucose (made in choloroplast) -> waste product is released into the air
|
|
|
who does photosynthesis
|
plants
single celled algae |
|
|
what is photosynthesis
|
process of making glucose using sunlight
|
|
|
where does photo. happen
|
chloroplast
|
|
|
when does photo. happen
|
during daytime
|
|
|
how does photo. happen
|
carbon dioxide + water + energy = glucose + oxygen
|
|
|
who does aerobic/cellular respiration
|
plants
animals |
|
|
what is aerobic /cellular respiration
|
the process of cells making food
|
|
|
where does aerobic/cellular respiration happen
|
mitochondria
|
|
|
when does aerobic/cellular respiration happen
|
all the time
|
|
|
how does aerobic/cellular respiration happen
|
glucose + oxygen = carbon dioxide + water + energy
|
|
|
explain how the circulatory & digestive system work together inside and organism to help the organism live
|
food goes to stomach, enzyems digest the food, nutirients get absorbed in small bowel - goes to circulation - via blood nutirents goes to diff parts of body
|
|
|
explain how the respiratory system and nervous system work together to help an organism live
|
nervous sys has breathing center that controls lungs, ratio of CO2 in lungs which the brain uses to determine if lungs should breathe slow or fast - when CO2 goes up - brain makes body breathe faster
