Where can you find seeds? In our food In our backyards

5
Nourishment: The seed provides food for the young plant while it is developing the parts it needs to make its own food. Seed Dispersal: The design of the seed helps the seed travel to other places to germinate.

10
Functions Keep the plants in place Absorbs water and nutrients from the soil Some roots help the plant by storing food.
11
Taproots Large Grow deep into the soil. Are able to store food. Fibrous Roots Thin and stringy Lie close to the surface Can often be found growing side by side with taproots. Adventitious Roots Strong and can be thin or thick. Develop to help the plant climb Found in ivies and vines
12
Functions: Supports the plant and gives them shape. Contain small tubes: Xylem carries water and minerals from the roots Phloem: carries food that is made in the leaf to the rest of the plants.
13
Where plants make their own food in a process called photosynthesis. Many kinds of leaves Needles Broad Leaves
14
Found on most conifers and cacti. They do not shed their needles in the Fall. Their shape helps prevent water loss.
15
Leaves can be found in all shapes and sizes based on their environment. In cold climates plants shed their leaves because there is less sunlight for photosynthesis to take place and the plant needs to save its energy.

17
A process plants use to make their own food Plants’ leaves contain chlorophyll Chlorophyll (green color) makes photosynthesis possible
19
THE SUNLIGHT IS COMBINED WITH WATER AND NUTRIENTS FROM THE SOIL THAT HAS BEEN ABSORBED BY THE ROOTS. CARBON DIOXIDE EXHALED BY ANIMALS IS ALSO ABSORBED BY THE LEAVES
21
Oxygen When the process of photosynthesis is complete, the plant has made 2 things.: Sugar : The food the plant has made for itself Oxygen: A waste that is released by the plant that we need to survive.
22
Animals and plants need each other to survive. Plants give animals oxygen to breath and live. We give plants carbon dioxide to make food.
23
What is transpiration? Water is absorbed from the roots of a plant and travels to the leaf. The sun heats the water in the leaf turning the water from a liquid to a gas called water vapor The water is released into the air through tiny holes called stomata http://www.youtube.com/watch?v=At1BJJDcXhk&feature=related
24
What is the function of the flower in a plant? Attract insects and animals using bright colors and wonderful scents. Produce or make the fruit and seeds of the plant
26
The stamen is the part of the flower that makes pollen. Pollen is fine powder needed for pollination.
27
Pistil The pistil is made up of 3 main parts: Stigma Collects pollen Style Separates the stigma from the ovary Ovary Where the fruit/seeds form.
28
http://videos.howstuffworks.com/hsw/9756- our-flowering-world-flower-parts-video.htm What is pollination? Pollination is how seeds are formed to create a new plant. Pollination occurs when pollen from the anther on the top of the stamen is carried to the stigma on the top of the pistil. The pollen travels down the pistil through the style to the ovary There the pollen fertilizes an ovule and a new fruit/seed is formed

Teachers' Domain: Life Cycle of a Seed Plant
31
What are spores? Spores are tiny, seed like spots on the underside of certain plants like ferns. Spores contain stored food and will fall of the plant and germinate(grow)if the conditions around them are right.
32
Bulbs A type of bud that grows underground. Tulips grow from a bulb. Runners Some plants can grow from the stem of an older plant. A spider plant can reproduce this way.
33
Grafting Combining two different plants to create a new and better plant. You can attach one apple tree to the trunk of another apple tree to make a better tasting apple
34
Tubers Are swollen underground stems. We often eat them. Tubers develop “eyes” that will develop into a new plant.
