Flower Reproduction
Flower Reproduction - NWMS
Term | Definition |
---|---|
Sepal | Special leaves that support and protect the flower bud. Located underneath the petals of the flower. |
Stamen | Male reproductive part of a flower |
Filament | Thread-like (Stalk part) part of the stamen that connects the anther to the flower. |
Anther | Structure of a flower that produces pollen grains and includes nectar |
Pollen | Male plant reproductive cell |
Style | Tube that carries the pollen in the pistil from the stigma to the ovary |
Pistil | Female reproductive part of a flower |
Stigma | Top part of the pistil, where the pollen enters |
Ovary | Part of the female reproductive organ containing eggs |
Eggs | Female plant reproductive cell |
Seed | Fertilized egg |
Pollination | Transfer of pollen grains from the anther to the stigma of a flower |
Fertilization | The uniting (joining) of a sperm from pollen grains and eggs from the ovary takes place in this process |
Germination | The growth of the root through the seed coat, the seedling growing, then the shoot appears and breaks through the soil and the first leaves unfold |
Petal | Colorful leaves that surround the reproductive parts of a flower |
Embryo | Young plant in a seed |
Thorns | Where a plant would have a branch, this defense mechanism would be there instead |
Seed Coat | Protective covering of a seed before it starts to grow |
Petal | Colorful part of a flower to attract pollinators |
Thigmotropism | Plant's response to touch |
Hydrotropism | Plant's response to water |
Gravitropism | Plant's response to gravity |
Phototropism | Plant's response to light |
Thermotropism | Plant's response to heat |
Dormancy | When a plant's activity or growth stops over a period of time |
Xylem | Tubes in a vascular plant that transport water and nutrients from the roots to the rest of the plant |
Phloem | Tubes in a vascular plant that transport food from the leaves to the rest of the plant |
Photosynthesis | Process that plants go through to create their own food (glucose) |
Transpiration | Process where water is evaporation exits the leaves from plants with the help of stomata and guard cells |
Respiration | Process that plant's go through to release their energy to help them grow and heal |
Leaves | Where photosynthesis, transpiration, and respiration occur on a plant |
Roots | Soak up water and nutrients from the soil and stores extra food |
Stem | Helps support the plant and has the xylem and phloem |
Flower | Contains the male and female parts of the plant |
Taproot | One main root with several smaller roots (example: carrot) |
Fibrous Root | Several roots branch off to create a mass of roots |
Thorns | Any sharp body part of a plant |
Poison | Harmful chemical that plants have in stems and leaves |
