In active transport, carrier proteins are used, which use energy in the form of ATP, to
transport molecules against concentration gradient of cell wall.
transport molecules along concentration gradient of cell membrane.
transport molecules against concentration gradient of cell membrane.
transport molecules along concentration gradient of cell wall.
C.
transport molecules against concentration gradient of cell membrane.
In active transport, carrier proteins which are located at membrane, use energy in the form of ATP to transport molecules against concentration gradient of cell membrane. Transportation rate reaches maximwn when all carrier proteins are being used or are saturated. These proteins are very specific to certain substances and are sensitive to inhibitors.
Bacteria, fungi, lower plants survive in adverse conditions by
diapause
suspended growth
migration
formation of thick walled spores.
structure of lenticel
hydathode showing gaseous vapour exchange
fungus reproducing by spore formation
algae reproducing by spore formation.

Cleistogamy is leading over anthesis because
pollination agent is not required
it assures heterozygosity
it favours insect pollination
it allows xenogamy
