Plants
Vocabulary relating to Plants
Term | Definition |
---|---|
Plant | Multicellular, eukaryotic organisms that makes their own sugar from sunlight through photosynthesis, |
Leaf | The part of a plant that absorbs sunlight for photosynthesis. Often covered in a waxy layer to reduce evaporation. |
Stem | The part of a plant that supports the plant as it grows. It moves water and sugar throughout the plant. |
Roots | The part of the plant that absorbs water from the soil. Also anchors the plant into the ground, and holds the soil in place to reduce erosion. |
Erosion | The removal of soil by wind, rain, running water, or other sources. |
Seed | The protective shell of a plant embryo. Seeds are formed when a flower is pollinated. |
Fruit | The tissue that surrounds the seed. Fruits usually help the seed move (seed dispersal) in some way. |
Flower | The reproductive structures of plants. |
Petal | Brightly colored parts of a flower that attract pollinators like bees and birds |
Sepal | Leaves that surround and protect a growing flower bud |
Stamen | The part of the flower that produces pollen (the male gamete in plants) |
Pistil | The part of the flower that produces eggs (the female gamete in plants) |
Ovary | Part of the pistil, After the egg becomes pollinated, the ovary becomes a fruit. |
Seed dispersal | The way plants get their seeds to spread far away from where the parent plant is growing. |
Seed dispersal- wind | As the wind blows, it carries the seeds to new locations |
Seed dispersal- water | Seeds float in moving water to reach new locations |
Seed dispersal- animals | Seeds that rely on animals to move them to a new place. |
Seed dispersal- expulsion | Pressure builds up inside of plants until they explode, which launches seeds to new places. |
Germination | The process of a plant embryo breaking out of the seed. Creates a root that grows downwards and a stem and leaf that grow upwards. |
Sprout/sapling | A baby plant that has successfully germinated and started to grow. |
Mature plant | As time passes, the plant continues to grow and develop. It is considered mature when it begins to produce flowers. |
Pollination | The process of plant pollen being combined with ovules. This is how plants reproduce. |
Seed creation | Following successful pollination, a seed is created with the plant embryo inside. |
