Unit A Chapter 1-Types of PlantsVocabulary

leaves-the part of the plant that grows out of the stem; it takes in air and light that the plant needs.

tuber-fleshy underground root or stem as in a potato

stem-a plant part that connects the roots with the leaves of a plant and supports the plant above ground; it carries water from the roots to other parts of the plant.

roots-the part of the plant that holds the plant in the ground and takes in water and minerals from the soil.

seedling-a young plant.

seed-the first stage in the growth of many plants.

chlorophyll-the substance that gives plants their green color; it helps the plant use energy from the sun to make food.

photosynthesis-the food making process of plants.

simple plant -a plant that has no roots, stems or leaves.

cells -small units that make up all living things.

Unit A Chapter 1What Plants Need

Plants need water, light, soil, and air.

Even though plants may look very different from each other, they all have the same parts: 1. root 2. stem 3. leaves.

The stem carries water and nutrients from the roots to other parts of the plant.

Leaves take in the air and light a plant needs.

Roots hold the plant in the ground. They take in water and nutrients from the soil.

Cellshttp://www.learn360.com/ShowVideo.aspx?ID=575124&PageSize=50&SearchText=microscopic+cells

All living things are made up of small units called cells. Every kind of cell does a special job. A leaf cell helps the plant make food, a root cell helps a plant absorb water and nutrients from the soil. All cells in living things work together to keep the organism healthy.

The jade plant has leaves that are small, thick and shiny. The edges are smooth. Succulent plants are very low maintenance.

The black oak leaf is long and wide with rough edges.

The Japanese maple leaf is thin and red. The edges are rough.

Leaves help plants get the light and air they need. When you observe a leaf, the size, shape, and edges can help you discover it’s

origin.

Different Types of Plants

Moss is a simple plant which means it doesn’t have roots, stems or leaves. All parts of the moss plant take in water and nutrients directly from the environment.

A seed is the first stage of growth for plants that have roots, stems and leaves. When a small plant breaks out of the seed, it germinates. When the seed breaks open, a seedling ,or young plant appears.

Plants without seeds are simple plants that use spores to reproduce. A fern has spores. There are hundreds of spores on each dot.

Seeds carry information needed to grow plants that look like the plant they came from.

Some plants have flowers that form seeds.

Some plants can be grown from other plants. If you place a leaf or a piece of a stem called a “cutting” in water, it will form a root.

Some plants have seeds in the shape of cones.

Inside a Seed

A seedling lives inside every seed.

Most of the inside of the seed is stored food . The young plant uses the food to grow when the seed sprouts.

The seed coat protects the young plant inside the seed.

Inside a Flower

Seeds are spread by air, water, animals, people and bolting.

Some seeds, such as the Bauhinia Purpurea shoot up to 50 feet, as if out of a cannon.

Bolting is when a plant goes from being mostly leaf based to mostly flower (seed) based in order to make the next generation of plants.

Seeds move from one place to another by water.

Basil plant bolting or “going to seed”.

Seeds can be spread by attaching themselves to animals.

Seeds move from one place to another by wind.

Photosynthesis is the food-making process of a plant. The four things plants need for photosynthesis are:

1.chlorophyll, 2.sunlight, 3.water and 4.carbon dioxide.

Plants get their green color from chlorophyll . Chlorophyll helps a plant use energy from the sun, along with water and carbon dioxide (a gas in the air) to make food (a kind of sugar). Then the plant gives off oxygen through it’s leaves.

How plants use food.

4. Other plants store food in their fruit which makes it tasty for animals. The animals eat the fruit and spread the seeds.

3. Plants store food in their stems and roots to use it later.

2. Plants use food to make seeds.

1. Plants use food they make to grow larger.
