1. Energy from Plants
Chapter 2

2. Lesson 1 What are the plants’ characteristics?
Plants are made up of many cells.
These cells all do different jobs in the plant
Plants have special cells they use to absorb water and nutrients from the soil
Plants contain Chlorophyll, which makes them green

3. How Plants Make Food Photosynthesis – The process of making sugar
Plants use sugar as food
Carbon dioxide is absorbed from the air, water is absorbed from the soil, and chloroplasts trap the sunlight

4. PHOTOSYNTHESIS The plant uses the sugars it makes
The plant releases Oxygen that we breathe

5. Chloroplasts Water, food, and gases pass in and out of the cell
through the Cell Membrane
Chloroplasts contain green
material that traps sunlight

Parts of a Plant
Lesson 2
Leaves
Their job
is to produce
food
so the plant can survive
Leaves can come
in many shapes
and sizes

8. Stems Can be as thick as a tree trunk or as thin as a blade of grass
Have 2 major functions
1. carry water, minerals and food between the roots and leaves
2. Support the plant, holding up the leaves so they can get sunlight

9. Roots Anchor or hold the plant to the ground
Absorb or take in water and mineral nutrients from the soil
Fibrous Roots
Grow away from the plant in search of water
Taproots
Has a large main root, called the taproot.
It grows straight down
Stores food for the plant

10. How Plants Reproduce Sepal Petal
Petals-colorful outer layer of flowers that help protect the insides that make new plants
Sepals- the small, green leaves below the petals. They cover and protect the flower as it grows inside the bud

11. How Plants Reproduce STAMEN
Pistil-small knoblike structures in the middle of the plant
Stamens-smaller stalks surrounding the pistil. Pollen is made here.
STAMEN

12. How Do Plants Reproduce?

13. Pollen on the Move
Pollen has to move from the stamen to a pistil in order for a seed to form.
HOW CAN THIS HAPPEN???
Animals help this happen!
Animals are attracted by the colors of the petals and to eat the nectar deep inside the flower.
Pollen from the stamen is rubbed off onto the animals body
The pollen is then rubbed off onto the pistil of the next flower the animal visits.

14. Pollen in the Move
Wind also can blow pollen from the stamen of one plant to the pistil of another
After the fertilization, the flower begins to dry up and fall off
A seed develops inside

16. Life Cycle of a Plant
Lesson 4

17. Seeds on the Move
Seeds have to move away from each other to have room to grow.
If they grew too close to one another they would compete for water, nutrients from the soil, and sunlight.

18. Animal Helpers
Animals eat fruit and when they do they eat the seeds also.
The seed will pass through the digestive system onto the ground in the animal’s droppings.
The animal will usually carry the seeds far from the adult plant so this helps scatter the seeds

19. Wind as a Helper
Many seeds have wing-shaped seeds to carry them far from the adult plant.
When the seeds land, many are buried and new plants grow

20. Water as a Helper Water can carry seeds from one location to another.
Coconut seeds can float from one island to another and create new trees.

21. New Plants from Plant Parts
Some plants grow from stems, roots, or leaves
Bulbs are underground stems that grow into new plants
Potato plants sprout new plants right from the potato
