1. Systems in Plants Nelson 4.1 pg. 125-128
Plants are multicellular organisms

2. Plants They are multicellular organisms
They include mosses, ferns, conifers and flowering plants
They have two distinguishing features: they are green in colour and can not move from place to place
What causes their green colour?
- chlorophyll from their chloroplast organelle

3. Plants perform photosynthesis to make their own food
What do plants require in order to survive?
Plants need to exchange gases with their surroundings
Plants require an internal transportation system to move water and nutrients around within their bodies
They must have a way of reproducing

4. Flowering plants have two main body systems: a root system and a shoot system
What is the root system made up of?
What is the shoot system made up of?

5. Main types of Plant Tissue Systems
Dermal tissue system: is the tissue that forms the outer surface of the plant
Vascular tissue system: is made up of tissue that transports water, minerals and nutrients throughout the plant
Ground tissue system: make up all the other structures within a plant

6. The Root System This is part of the plant that grows below the ground
This system anchors the plant, absorbs water and minerals from the soil and stores food
Which roots do we eat as food?
- radishes
-carrots

7. The Shoot System
This system is specialized to conduct photosynthesis and produce flowers for sexual reproduction
The shoot system of flowers is made up of three parts. What are they?
- leaf
- flower
- stem

8. The Leaf
Look at this leaf!!! This leaf grows in the rainforests of Panama

9. The Leaf This is where photosynthesis occurs
Light energy + carbon dioxide+ water chlorophyll- glucose + oxygen
The chloroplast is the organelle that performs photosynthesis
Chloroplasts

10. Chloroplast
Chloroplasts contain flat, disc-like structures called thylakoids
Thylakoids are arranged in stacks called grana
The grana are the solar collectors using chlorophyll to convert sun energy into glucose

11. Leaves are used in a variety of ways such as…..
- food
- medicine
- clothing ( i.e. hats)

12. The Flower Flowers are specialized for sexual reproduction
Flowers contain male / female reproductive structures
The male reproductive structure produce pollen grains
The female reproductive structure produces eggs
Eggs are fertilized by pollen
After pollination, the female flower forms seeds

13. Reproductive Flower Parts
A portion of the flower sticks out

14. Female Flower Parts
Female parts

15. Pollination occurs with the help of wind or animals
Which flowering plants use the wind for pollination?
- grasses
- trees
Which types of flowering plants use animals for pollination?
- most flowers that are colourful will attract animals
Did you know…
Rice, wheat, corn, vanilla, chocolate, coffee, bananas, apples, mangos, cotton originate from flowers

16. The Stem
The stem has several functions such as
Supports the branches, leaves, and flowers and provides a way to transport materials
The stem has a significant amount of vascular tissue to carry substances to and from roots, leaves, flowers and fruits

17. Your Turn List the foods that come from plant stems.
