THE GREAT PLANT ESCAPE

BUD SPROUT

My name is Bud. My friend Sprout & I are helping the Detective finds clues to solve the great mysteries of plants.

We will need your help in doing experiments, finding clues & solving problems.

CASE 1

To solve Case 1 your goals are to:

•Identify plant parts

•Plant part functions

•How plants grow

CASE BRIEF

Key ideas:

* Plants made of different parts, each part has a job; parts can help us identify plants

*You can eat certain plant parts. They are important food sources for both humans and other animals.

7 Basic needs of plants:*temperature

*light

*water

*air

*nutrients

*time

*room to grow

*Plants can be grown both indoors and outdoors for food, shelter, clothing, medicine, energy, and pleasure.

Plant StructurePlant Structure

Plants can be either:

herbaceousherbaceous

Plants with stems that are usually soft. These stems die back to the ground every year. OR...

woodywoody

Stems that are hard and stiff. These stems usually don't die back to the ground during the winter. These are stems we use to make furniture and houses.

Life CycleLife Cycle

A plant's life cycle describes how long a plant lives or how long it takes to grow, flower, and set seed. Plants can be either an annual, perennial, or biennial.

AnnuaAnnuall A plant that completes its life cycle in one growing season. It will grow, flower, set seed, and die

Examples: marigolds, tomatoes, and petunias.

Perennial Perennial

A plant that lives for 3 or more years. It can grow, flower, and set seed for many years.Examples: daisies,

chrysanthemums, and roses.

(think bushes!)

Biennial Biennial A plant that needs two growing seasons to complete its life cycle. Produces leaves one season, rests in winter and grows flowers & seeds the next season.

Examples: parsley, carrots, & foxglove.

Plant Parts - Roots

The roots provide support - anchor the plant & absorb water and nutrients needed for growth.

ROOT SYSTEMSROOT SYSTEMS

Taproot system

A root with a few branches that is very thick and swollen. Carrots & potatoes are example.

fibrous root systemfibrous root system

Some plants have a root system like this. It is a bunch of very fine roots all together. Grass plants have fibrous roots.

Plant Parts - Plant Parts - StemsStemsStems carry water and

nutrients taken up by the roots to the leaves. They also provide support. Without stem, there would be nothing to hold up leaves or flowers!

The cells of stems, xylem & phloem are located in long strands called vascular bundles.

The cells that do this work are called:

xylem cellsxylem cells

The cells that move water in plants.

phloem cellsphloem cells

Cells of a plant that move food down the stem to other parts of the plant.

Plant Parts - LeavesPlant Parts - Leaves

Leaves are the food making factories of green plants.

Leaves can be simple, made of a single leaf blade

OR...

or compound in which the leaf blade is divided into separate leaflets
