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
