Parts of a Plant

Roots Stem Leaves Flower (Fruit) (Seeds)

Video: 1:24

1. Roots

Job: Anchor plant Absorb water and minerals

2 Types:1. Tap Roots – One large main root

with smaller side branches – deep2. Fibrous Roots – many, same sized

roots spread out in many directions

2. Stem

Job: Hold up plants’ leaves and flowers Transport water and minerals

Xylem – From roots to the top (“High to the sky”)

Phloem – From leaves down to the roots (“Flows like a waterfall”)

Tree Trunks: Annual Rings – each ring = 1 year The more rain, the thicker the ring

3. Leaves

Job: MAKE FOOD (photosynthesis)

Parts of a Leaf: 1. Petiole –

connects leaf & stem

2. Blade – flat part

3. Veins

Ways to Identify LeavesSimple Compound

Smooth Jagged

Lobed Non-lobed

4. Flower

Job: Produce seeds Attract insects, birds (to spread

pollen)

Parts of a Flower

Petals Colorful

Pistil (female) Sticky Where seeds

form Stamen (male)

Makes pollen

Parts of the Stamen and Pistil

Video: 3:14

Pollination Process where pollen is transferred

by insects, birds, wind, etc. from stamen to pistil in order to form seeds.

Photosynthesis Chloroplasts –

structures in plant cells that hold chlorophyll

Chlorophyll – green pigment that traps sunlight

Why do leaves change color in the fall?

Photosynthesis (continued)

With energy from the SUN,

Carbon Dioxide Glucose (food)

+ + Water OxygenVideo Photosynthesis

11:57

Photosynthesis – process where plants make their own food by using energy from the sun.

Transpiration

Transpiration – process where plants release water through their stomata

Stomata – tiny holes on underside of leaves

Plant Adaptations

Phototropism- plant adaptation that causes a plant to grow towards sunlight

Hydrotropism – plant adaptation that causes a plant to grow towards water

Geotropism – plant adaptation that causes a plant to grow towards the center of the earth

Thigmotropism – causes tendrils to wrap around other objects

Life Cycle of a Tree Germination (Sprouting) – embryo sprouts

Seedling – stem appears and leaves develop

**(Then we have the seasons fall & winter) Sapling- ** (Then in the SPRING)

~ new leaves appear~ bark forms~ roots spread

Tree~ grows its first flowers~ trunk measures 4 inches in diameter
