Flower Function
Plant Reproduction and Life Cycle Review
Term | Definition |
---|---|
flowers | The reproductive structure of some plants. |
germination | The early stage of seed growth. |
pollination | The transfer of pollen from the male part to the female part of a plant. |
pollen grains | The male reproductive structure of a plant (sperm cells). |
seed | A structure that contains a young plant in a protective covering. |
fertilization | The joining of a sperm cell (pollen) and an egg cell (ovule). |
sexual reproduction | A process that involves two parent plants to form a new organism that differs from the parents. |
flower | A structure made by some plants to house the seed and attract dispersers. |
plant propagation | The process of growing new plants from plant parts. |
asexual reproduction | A process that involves only one parent plant and produces offspring identical to the parent. |
pistil | female part (stigma + style + ovary) |
stamen | male part (anther + filament) |
anther | makes pollen |
filament | holds up pollen-making part |
stigma | collects pollen and is sticky |
style | stalk that contains the pollen tube |
ovary | contains ovule eggs |
ovule | egg sex cells (female) |
pollen | male sex cells |
petal | scent and color attract pollinators |
sepal | protects undeveloped or closed flowers |
stem | supports flower |
male | gender of anther/filament/stamen |
female | gender of pistil/stigma/style/ovary |
vegetative propagation | tubers/runners/roots/stems/leaf cuttings/bulbs |
dispersed/sent out | method that moves seeds away by wind/water/animals/digestion/bursting/humans |
zygote | ovule egg + pollen sperm form a(n) ___ |
seeds | pod/fleshy/shell are types of ___ |
germination | 1st life cycle stage (seed sprouts) |
plant development | 2nd life cycle stage (reproductive structures grow) |
fertilization | 3rd life cycle stage (ovule + pollen) |
seed development | 4th life cycle stage (fertilizes ovule becomes ...) |
