Welcome to TicTac Town TIC TAC Plant Parts 4th grade Jessica Runyan Identify the function of specific plant and animal parts.
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 ferns seed-bearing plants flowering plants
Parts of a Vascular Plant • Roots • Stem • Leaves • Ovule • Stigma • Ovary • Petal • Anther
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 • 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 • 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 • This part contains the egg cell.
Stigma • tip of pistil which catches the pollen grains
Ovary • where ovules are made
Petal • colorful leaf that helps attract insects
Anther • This part of the stamen contains pollen.
What is pollen? • The fine powder like material consisting of pollen grains that is produced by the anthers of seed plants. • http://www.pollen.com/Pollen.com.asp After you strip away the blossom of the male flower, the pollen is readily visible.
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 • 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.
