Basic Parts of the Plant

1
Basic Parts of the Plant

• VEGETATIVE PARTS
• Roots
• Stems
• Leaves
• REPRODUCTIVE PARTS
• Flower
• Fruits
• Seeds

2
Functions of Roots

• 1. Anchor Plant- Hold up
• 2. Absorb water and minerals
• 3. Transport water and minerals to stem
• 4. Store Food (Carrot)

3
Functions of Stems

• 1. Xylem transports water minerals to leaves
• Phloem carries food down from the leaves to the
  root
• Support the leaves and display them to light
• Store Food

4
Functions of Leaves

• Leaves make food through photosynthesis
• Take in carbon dioxide and release oxygen
• Store food- Onions store food in its leaves

5
Different type of Roots

• A. Tap Root- Ex. Carrots
• Has a main or primary root
• B. Fibrous Root- Ex. Corn
• -No single primary roots.
• -Numerous short roots attached to main stem

6

• Root hairs
• Tiny one celled hair located near the tips of the
  roots.
• Absorb water and minerals from soil

7
Specialized Stems

• C. Tuber (potato, caladium)
• Short, thick underground stem
• Food storage area

8
Flowers

• Help plants in sexual reproduction or
  propagation
• Produce seeds and fruit
• The flower ovary becomes the fruit.
• The eggs or ovules become seeds.

9
Complete and Incomplete Flowers

• Flowers have four main parts
• Complete have all four main parts
• Sepals- protect the young flower (flower bud)
• Petals- brightly colored to attract insects.
• Stamens.- Male flower contains anther and
  filament
• Pistils- Female flower contains ovary, style
  Stigma
• If a flower is missing one of the four parts, it
  is called incomplete.

10
Parts of the Flower

• Sepals- usually have the green color of a leaf.
• Outer covering of the flower bud
• Protects the stamens and pistils when flower is
  in bud stage

11
Parts of the Flower

• Petals (a group of petalscorolla)
• Brightly colored
• Protects stamen and pistils
• Attracts pollinating insects

12
Parts of the Flower

• Stamens
• Male Reproductive part
• Anther-produces pollen
• Filament-supports the anther

13
Parts of the Flower

• Pistil
• Female reproductive part
• Ovary-develops into the fruit
• Enlarged portion at base of pistil
• Produces ovules which develop into seeds
• Stigma
• Holds the pollen grains

14

• Style
• Connects the stigma with ovary
• Supports the stigma so that it can be pollinated
