Bio Flashcards
(26 cards)
Autotrophs ex :
green plants , some type of bacteria
chemical reactions equal
photosynthesis process
obtain their food
heterotrophic
example of parasites/heterotrophic nutrition
bilharzia worms and orobanche plant
example of saprophytes /heterotrophic nutrition
some fungi ; bread mould fungus and saprophytic bacteria
example of holozoic heterotrophs ; Herbivores
feed on plants, like rabbits cattle horses
example of holozoic heterotrophs ;Carnivores
feed on animals, like
dogs cats, wolves and eagles
example of holozoic heterotrophs ;Omnivores
feed on both animals and plants like
human
whats the ability of Parasites
its depends on a living organism (host) in building its body and causing harms to the host
whats the ability of Saprophytes
its decompose the organic remains of the dead body
or non living (bread)
transport vessels
xylem
Who is responsible for roots regeneration
elongation zone of roots
the root hair have a thin wall
to permit the the passage of water and salts through it
the root hair being large in number and protruding outside
to increase the surface area of water and salts absorption
Diffusion movement
movement of molecules or (((((((ions))))))) from highly concentrated medium to low concentration
whats the semi-permeable prevent
sugar,amino acids large sized molecules
example of permeable
cellulose walls
example of impermeable
walls cover by lignin(xylem)
or cutin or suberin (cover epidermis leaf steam)
example of semi- permeable
plasma membranes
(very tiny membrane pores)
the root hair covered by
a thin colloidal layer
cellulose and plasma walls
absorb water by imbibition phenomenon
enter in the formation of the energy carrier compounds (ATP)
Phoshours
is important for the building-up of some co-enzymes which are required for the accomplishment of photosynthesis process
iron
the nitrate, phosphate, sulphate
converted the carbohydrates into proteins
