Plant Parts and Their Functions

Learning Target: I can describe the basic structures &

functions of plants.

Criteria for Success

❏Describe how special plant cell parts support the function in plants

❏Describe the function of stems, leaves, roots

❏Understand various plant processes

❏Understand various tropisms

Let’s begin by watching this awesome intro video clip!

Plant Structures and Functions

I Plants- organisms that typically grow in permanent sites; produce

their own food; provide oxygen for other organisms.

II Plant Parts:

support leaves; stores and carries water and nutrients

to leaves; transport sugar to roots.

makes food; helps exchange gases in the envioronment

through stomata (small openings in the leaves).

absorbs water & minerals; anchors plant to soil;

supports the plant

Examples of Two Root Types

Taproot examples Fibrous roots

Check For Understanding- Think about it!

Make a connection between the two

special parts of a plant cell and the parts

of a plant from the previous slide.

Plant Processes

III Plant Processes

1-Absorption = taking in water 2-

and nutrients

Transpiration = release of

water vapor from stomata in

leaves

Tool Box #54 Continued

3- Photosynthesis = the process (in leaves) of converting light

energy from the Sun to chemical energy (food= glucose)

a) Chloroplasts role = provide chlorophyll

b) Stomata role = allows the exchange of gases .

Let’s Watch The Video Clip on Photosynthesis!

Tool Box #54 Continued

4- Cellular Respiration= the process that plant cells use to

convert energy stored in glucose into useable chemical energy

-occurs in the cytoplasm/ mitochondria of the cells

- ATP (adenosine triphoshate) = molecule where

energy is stored

IV-TropismsTropisms = plant growth toward or away from an external (outside) stimulus

A- Phototropism = growth toward light

B- Gravitropism = growth to and away from the force of gravity ; first root- grows

downward (pos.); stems/leaves –grow upward (neg.)

Tool Box #54 continued

C- Thigmotropism = a plants response to touch (coiling

around another plant; roots wrapping around a rock in soil)

Exit Slip

1- Plant life is so important to all life on Earth because….

2- Plant life is so important to all life on Earth but….

3-Plant life is so important to all life on Earth so….

Enrichment- Copy and answer:

1- What analogy can be

given to compare

absorption and

transpiration in plants to

absorption and

transpiration in humans?

2- Explain one similarity

and one difference

between plants and

animals with regard to

stimuli ( a thing or event

that evokes a reaction).
