Introduction to PlantsAll living things depend
on plants for food/life. Plants have a life cycle
that begins with a part of the plant

• Sometimes it is a part of the root that
  becomes a new plant e.g. sweet potato 
  Sometimes it is a seed.  Sometimes it is a leaf
  that becomes a new plant.  Sometimes it is a
  part of the stem e.g. white potato. Our lesson
  will use seeds to start a plant.

Parts of a plant

• Plants have four main parts  Roots Stems L
  eaves Flowers/Fruit

What do roots do?

•  Roots hold the soil in place in the
  ground. Roots provide food to the plant. They
  take minerals, oxygen and water from the soil and
  send them through the stem to all parts of the
  plant. Roots sometimes become something to eat,
  e.g. carrots and beets. Root hairs are the
  roots mouth.

5
What do leaves do?  

•  Leaves make food for the plant. They use
  water, sunlight, carbon dioxide to make sugar or
  glucose which the plant uses for its food. The
  process by which the leaves makes glucose is
  called photosynthesis. Leaves give off oxygen
  and water.

Vocabulary Words

• 1. Chlorophyll the green material in plants.2.
  Sunlight- provides energy to make
  food.3. Water.4. Carbon dioxide-a gas given off
  by people and animals as they breathe.5. Oxygen
  is a gas taken in by animals as they breathe.

7
What do stems do?

•  Stems hold the plant upright. Stems carry
  water and minerals from the roots to the
  leaves. Stems can also become new plants.

8
What do flowers do?

•  The flowers job is to make seeds. Flowers
  produce pollen - which is a yellow dust needed to
  form seeds. Flowers can become fruits or
  vegetables or make a room look pretty (decorate).

Conclusion
The main parts of a plant are the leaves, stem,
flowers/fruit and roots. They all have their own
job to do so that the plant can continue its life
cycle and survive like all living things.
