Feeding Flashcards
why does life require food
to maintain normal cellular function , replication and reproduction
2 types of autotroph
chemoautotroph
photoautotroph
autotroph meaning
synthesis own food but acquire nutrients
chemoautotroph meaning
bacteria that synthesis food using inorganic compounds
photoautotroph meaning
green plants, bacteria and algae that use light to synthesis food
heterotroph meaning
unable to make own food so must consume other forms of life
6 types of heterotroph
carnivore
insectivore
herbivore
omnivore
scavenger
detritrivores
detritivore meaning
eat soil , leaves and decaying matter
how are roots an adaption to living on land
- support nutrient and water uptake
- provide anchorage and support
- synthesis plant hormones
how are vascular systems an adaptation to living on land
- phloem transports sugar and xylem transports water and minerals
- lignin prevents xylem from collapsing due to hydrostatic pressure
- allows transport of sugar to large areas
importance of leaves for adaptation to living on land
- increase SA
4 feeding strategies
- phagocytosis
- diffusion
- filter feeding
- parasitism
how is diffusion used in feeding
transport of nutrients through cell membrane
how is phagocytosis a feeding strategy
engulfing of items of food or prey
what is filter feeding
straining organic matter and food from water
how do parasites feed
source food from other species that they attach to or live inside of
