Plant Structures

-specialized organs to take

care of all the needs of a plant.


Rootstake in water from the soil.

•hold the plant in the soil.

•store extra food that the plant doesn’t need right away.

allows water and minerals

to enter Root hair


Stem

•-transports food and water

•provides the plant with

•support


Leaves•- make food for the plant by

•using the sun’s energy in the

•process called

•photosynthesis.


flowers, fruits and seeds

•Flowers produce fruits

•Fruits contain seeds

Seeds produce new plants.

Plant and Animal Structures1. Movement

2. Support

3. Taking in

nutrients,

air, water

4. Coverings

•

many held to ground with

roots and can’t move, can

grow toward or away from stimuli

Stems

leaves, roots

bark, waxy covering

legs, arms,

feet, fins, tails

claws, wings

skeleton

mouth, teeth,

tongue, jaws, nose, beak, bill

hair, fur

shells, scales,

spines, feathers

LESSON REVIEW 1. Which lists two things that plants

and animals both need?

A. sunlight and water

B. water and space to move

C. water and safe place to live

D. space and safe place to live

LESSON REVIEW2. Which of these is part of a plant

but not an animal?

A. leg

B. root

C. fur

D. skeleton

LESSON REVIEW3. How are plant’s leaves like

human’s nose?

A. Both are covered with hair for protection.

B. Both take in sunlight to make food.

C. Both are used for movement

D. Both take in air


stimuli• things that provoke a

response or activity

tropism • plant’s response to stimuli


Types of stimuli

and plant’s reaction

- plant’s response to light

- tilts towards sunlight for

- leaves to receive energy

1. phototropism


2. geothropism

- plant’s response to gravity

- Roots will always grow downward


3. hydrotropism •Plant’s response to available

•water resources


4. thigmotropism •Plant’s response to touch

•(wrapping or moving away)


5. thermotropism •Plant’s response to heat/temperature

The answer is

Roots are adaptations for taking

in water and minerals from the

soil. Small hairs coming from

the root allow more area for

water and minerals to be taken

in.

Guided Instruction:

2. Which structures are responsible for

reproduction in plants?

a. cytoplasm and chloroplast

b. stamen and pistil

c. xylem and phloem

d. sepal and petal

The answer is

Insects pick up pollen from the

stamen. The pollen sticks to the

insect’s body and then rubs off onto

the pistil. This is called pollination

and a seed develops. This is how a

plant reproduces itself.

Guided Instruction:

3. Where does photosynthesis take place in

plants?

a. phloem

b. roots

c. leaves

d. flowers

The answer is

The leaf contains chloroplasts which

capture the energy from sunlight.

The leaf uses the energy to combine

water (from the roots) and carbon

dioxide (from the leaves) into a kind

of sugar called glucose. Glucose is

the plants food. This process is

called PHOTOSYNTHESIS.

Check Your Understanding

1. Katie put a flowering plant on her kitchen table. How would the flowers respond to light coming through the window?

a. The flowers would begin to wilt.

b. The flowers would change color.

c. The flowers would lean toward the window.

d. The flowers would open facing away from the window.

Record your answers. Check them at the end.


2. What might occur if a seed were to be planted upside down?

a. the roots would grow up instead of down

b. the stem would grow down

c. the roots would turn so that they were growing down

d. the seed would not grow


3. What might occur if all of the leaves were removed from a plant

a. the plant would not be able to support itself

b. the plant would not be able to take in water and nutrients

c. the plant would not produce seeds

d. the plant would not be able to survive because it could not make food


4. Which plant structure helps the leaves to reach toward the sunlight?

a. roots

b. stem

c. flower

d. fruit

Check Your Answers1. c-plants turn toward sunlight

2. c-roots grow downward, toward the pull of gravity

3. d- the leaves of a plant are where photosynthesis takes place, the production of food for the plant

4. b- the stem supports the plant which lifts up the leaves toward the sunlight
