asexual and sexual reproduction in plants Flashcards
give an example of artificial reproduction in plants
gardener taking a cutting from a plant, put in rooting powder and plant in soil
why do seeds need a food store
store of energy for growth until first leaves are exposed to light for photosynthesis
gametes fuse to form
zygote
why do seeds need warmth for growth
increased enzyme activity as substrates and enzymes have more kinetic energy therefore more collisions occur
what 3 parts of seed should you know about
seed coat, food store, embryo plant
give 4 differences between asexual and sexual reproduction
no gametes, genetically identical offspring, less energy involved in finding a mate, only 1 parent
why does germinating seed need oxygen
for aerobic respiration to release energy for growth
why does a germinating seed need water for growth
so enzymes are dissolved in water so reactions can’t take place
zygote divides by cell division to form
embryo
give an example of natural asexual reproduction in plants
runner in strawberry plants creates genetically identical plants
gametes fuse by this process
fertilization
what is correct term for sex cell
gamete
