Plant Organs

​Science - Classify Plants

​SC.5.L.14.2: Compare and contrast the function of organs and other physical structures of plants and animals, including humans, for example: some animals have skeletons for support—some with internal skeletons, others with exoskeletons—while some plants have stems for support.

​​TODAY’S TARGET: Classify flowering and nonflowering plants into major groups such as those that produce seeds, or those like ferns and mosses that produce spores, according to their physical characteristics. 

​​PLANT CLASSIFICATION

​I. Plants are first classified into flowering and nonflowering plants.

• All flowering plants produce seeds.

  • This is the function of a flower: to produce seeds.

Multiple Choice

All flowering plants produce _____________.

• flowers

• seeds

• non flowering

• bees

Multiple Choice

The function of a ___________ is to produce seeds.

• plant

• non flowering plant

• seed

• flower

• For nonflowering plants, there are several different ways to reproduce (Pine and Cypress Trees)

  • Some nonflowering plants produce cones.

  • Cones contain many seeds inside, and when the cone falls from the tree the seeds are released and can spread.

Multiple Choice

Some ____________ plants produce cones.

• green

• seed

• nonflowering

• flowering

Multiple Choice

When the cone falls from the tree, the seeds are __________.

• a flower

• don't go anywhere

• released and can spread.

• flowering plants

• Some nonflowering plants produce spores to reproduce (Ferns and Mosses)

  • Spores are like very fine powder that can float on the wind to spread.

Multiple Choice

Spores are like very fine powder that can _________.

• land on the ground

• float on the wind to spread.

• become a spore

• turn into wind

​II. ​Every plant uses the energy of the Sun to produce its own food.

• Photosynthesis: Plants combine carbon dioxide in the air with water. Plants use the energy of the Sun to break apart the molecules of carbon dioxide and water, and reassemble them to make sugar.

  • There is some leftover oxygen which the plants get rid of.

Multiple Choice

Every plant uses the __________to produce its own food.

• spores

• energy of the Sun

• cones

• moss

​III. Some plants use roots and stems to transport water to the parts of the plant that make food.

• some plants such as mosses and lichens absorb water directly from the air, and do not have roots.

Multiple Choice

Roots and stems _________ water to the parts of the plant.

• transport

• create

• lose

• give off

​IV. ​Plants with stems use those stems for support and transport.

• The stem lifts the food‐making leaves high above the ground to get sunlight.

• the stem supports the branches and leaves.

• stems are also transporting water and nutrients to the other parts of the plant

  • In trees, the stem is called a trunk.

Multiple Choice

Plants with stems use those stems for _____________.

• support and transport

• photosynthesis

• water

• food

​V. ​The outside covering of a plant protects the plant and keeps moisture inside.

• thick bark of a tree protects it from damage from sunlight, weather, insects, animals, and fire.

• The bark keeps moisture inside the plant

Multiple Choice

The ________ of a plant protects the plant and keeps moisture inside.

• roots

• stems

• leaves

• outside covering
