TIC TAC Plant Parts

4th grade

Jessica Runyan

Identify the function of specific plant and animal parts.


Vascular plants l.jpg
Vascular Plants

  • Vascular Plants contain two networks of tubes in their stems, leaves, and roots.

  • One of these networks transports water, and the other transports food made in the leaves to the other plant parts.


Types of vascular plants l.jpg
Types of Vascular Plants

ferns

seed-bearing plants

flowering plants


Parts of a vascular plant l.jpg
Parts of a Vascular Plant

  • Roots

  • Stem

  • Leaves

  • Ovule

  • Stigma

  • Ovary

  • Petal

  • Anther


Roots l.jpg
Roots

  • Water and nutrients from the soil enter the plant through the roots.

  • Water tubes in the roots carry water to water tubes in the stems.


Stems l.jpg
Stems

  • Water tubes in the stem then carry water to water tubes in the leaves.

  • Some of the water then evaporates into the air through a process called transpiration.


Leaves l.jpg
Leaves

  • Food tubes carry food made in the leaves to food tubes in the stem and roots.

  • Some food tubes run all the way from the leaves down to the roots.


Ovule l.jpg
Ovule

  • This part contains the egg cell.


Stigma l.jpg
Stigma

  • tip of pistil which catches the pollen grains


Ovary l.jpg
Ovary

  • where ovules are made


Petal l.jpg
Petal

  • colorful leaf that helps attract insects


Anther l.jpg
Anther

  • This part of the stamen contains pollen.


What is pollen l.jpg
What is pollen?

  • The fine powder like material consisting of pollen grains that is produced by the anthers of seed plants.

  • After you strip away the blossom of the male flower, the pollen is readily visible.


    What does a plant need to survive l.jpg
    What does a plant need to survive?

    • Soil

    • Light

    • Water

      _________________________________

      Plants may have adaptations in order to obtain these basic needs, much like the Venus Fly Trap.


    Stages in reproduction l.jpg
    Stages in Reproduction

    • An insect or the wind carries pollen grains from another flower to this one.

    • The pollen grains land on the stigma and a pollen tube grows down through the style to the ovary.

    • The nucleus of the pollen grain passes down the tube. It fertilizes the egg cell inside the ovule.

    • The fertilized egg cell develops into an embryo. The ovary becomes the fruit and the ovule becomes the seed.
