Study of Plants’ Parts Grade 4 Mr. Davis

Parts The seeds  The roots  The stems  The leaves  The flowers  The fruits 

Seeds or Bulbs  



Grows new plants Part of flowering plant that produces new plant Surrounded by a hard seed coat

Roots 





Holds plant in ground Root hairs Collects water and nutrients from soil Carries food to stem

Fibrous  Taproot 

2 types of roots 



Taproot Main root that has many smaller roots growing from it. Fibrous Thin roots that spread out in all directions just below soil.

Stems  



Carry nutrients and water Support system for plant body Holds leaves & branches upright

Leaves 



Absorbs sunlight and makes and stores food Photosynthesis 



 

Chlorophyll – green part of the plant Sunlight Carbon Dioxide Water

Flowers Produce seeds  Colorful  Contain perfume and nectar that attracts pollinators 

Fruits Protects the seeds  Could be eaten  Spreads the seeds 

Photosynthesis 

In photosynthesis carbon dioxide from the air and water from the soil react with the sun’s energy to form food for the plant



A primary difference between plants and animals is the plant’s ability to manufacture its own food.

Process 1.

2.

3.

Chlorophyll inside leaf takes sun, carbon dioxide, and water and turns it into sugar Plant uses sugar for food Plant produces Oxygen during this process

Respiration and Transpiration Respiration 

Plants (and animals) convert the sugars back into energy for growth and to energize life

Transpiration 



Water in the roots is pulled through the plant Cooling – 80% of the cooling effect of a shade tree is from the evaporative cooling effects of transpiration.

Non flowering plants 



Tendrils – Climbing plants use these to hold themselves up Spores – new plants grow from these
