1. PLANTS 3.L.1.1. Students are able to identify the basic structures, functions, and needs of plants in relation to their environment. Examples: leaves, stems, roots, flowers. By: Sydney Hart

2. VIDEO ON THE PARTS OF A PLANT!

3.  Provide support by anchoring the plant  Absorb water and nutrients needed for growth  Can store sugars and carbohydrates the a plant uses to carry out other functions.  Can either be a taproot or a fibrous root system  Taproot: like a carrot  Main root of plant  Fibrous root system: like turf grass  Mass of skinny roots spreading from the stem.

4.  Carry water and nutrients from the roots to the leaves.  Have xylem cells carry water and phloem cells carry food.  Provide support for the plant  Allow leaves to reach the sunlight to make food  Where leaves join the stem is called the node  Space between the leaves and stem is called the internode.

5.  The food making factories of green plants.  A simple leaf is a single leaf blade connected by a petiole to the stem.  Example: an Oak leaf or a Maple leaf  A compound leaf is a leaf made up of separate leaflets connected by a petiole to the stem.  Example: an Ash or a Locust.  Made to catch light and allow openings for air and water to go through.  Leaves have a waxy coating called a cuticle which protects the leaf  The veins carry water and nutrients within the leaf.  Leaves are the site of photosynthesis, the food making process.

6. In this process, carbon dioxide and water, when in the presence of the green pigment called chlorophyll, and sunlight, it is transformed into glucose. Which is the main source of food for green plants and produces the oxygen that we breathe in.

7.  Flowers may look pretty, but they are important when it comes to making the seeds.  The female parts of a flower are:  Pistil- the female part, located in the center of the flower. Has three different parts:  The stigma- the sticky knob at the top of the pistil.  The style- a long tube-like structure connected to the stigma and leads to the ovary.  The ovary- contains female egg cells called ovules.  Sepals are tiny green leaves that protect the flower during the budding process.

8.  Stamen- the male parts, they surround the pistil. It has two different parts:  The anther- produces pollen, the male reproductive part.  The filament- holds the anther up.

9. During fertilization, pollen lands on the stigma a tube grows down the style and into the ovary. Male reproductive cells travel down the tube and connect to the ovule. The fertilized ovule then becomes a seed.  The petals help attract pollinators like bees, butterflies, and bats.

10.  A fruit is the ripened ovary of a pant.  After being fertilized, the ovary swells and turns fleshy or hardens and becomes dry to protect the seeds.  Many fruits help seeds spread.  Some things we call vegetables but are really fruits like:  Tomatoes  Cucumbers  Beans

11.  A seed is an embryo containing leaves, stems, and roots that are waiting to be germinated s that they can grow.  All embryos have a coating surrounding them that is either thin or thick and hard.  Seeds contain short-term food supply called endosperm that is formed at fertilization but is not part of the embryo.  Seeds are plants ways of getting from one place to another.
