Plant Growth & DevelopmentGrade 2

Rachael D’Elia

Hi, my name is Buzz! I am going to help you learn all about plants and how they grow. I am also going to show you why they are so

important!

Concept Map: What will we learn about plants?

Plant growth and

development

What is a plant?

Definition of a plant

Parts of plants

What do plants need to grow? Photosynthesis

How do plants grow?

Seeds, bulbs, and cutting

Life cycle of plants

What do we use plants for?

Bees and plants need each other.

People use plants for many things.

WORD WALLSeed: It is small,

hard, smooth, and looks almost like a bean. (think of a sunflower seed).

A small plant enclosed in a hard covering, usually with some stored

food.

Cutting:Process of taking a piece of a plant apart and replanting that piece somewhere else, this usually produces new roots and another plant.

Bulb:An underground vertical shoot that has thick leaf bases used for food storage. Onions and garlic are examples of bulbs.

Plants: living organisms that obtain most of their energy from the sun.

Photosynthesis:Photosynthesis is the process that makes food for green plants. It uses light energy, carbon dioxide, and water in the presence of chlorophyll to create glucose (food)

Chlorophyll:Green pigment in plants that gives them their color. It absorbs light energy needed in making food.

Roots:Part of the plant that is underground and holds the plant in place. They absorb water and nutrients from the soil and carry them through the stem to the leaves, flowers, or fruit, much like veins work in humans!

What is a plant?A plant is a living organism that gets its energy from sunlight.

To be a plant, the plant’s leaves must have chlorophyll. The chlorophyll is what makes the green color and absorbs light from the sun for photosynthesis (how the plant gets food and energy).

What are the parts of a plant?

Great Plant Escape - Plant parts

Room to grow (or germinate)Roots need to be able to expand in the soil

What do Plants Need

to Grow?

Photosynthesis is the process that makes food for green plants. In photosynthesis, carbon dioxide and water in the presence of chlorophyll (the green pigment in leaves) and light energy from the sun are changed into glucose (a sugar). This energy rich sugar is the source of food used by green plants.

How do plants get their food?

How do plants grow?

Plants grow just like you and me. The way they grow is just different.

Green plants can start growing by seeds, bulbs, or cutting.

Plants continue to grow or germinate by going through the life cycle.

A seed is one way green plants begin to germinate.A seed is a tiny case that holds a small plant and food inside.Seeds can either drop from parent plants or be carried by wind,

animals, or water.

What is a seed?

What is a bulb?A bulb is a round underground structure.

In the center is a large bud that produces new plants.

The food is stored in the leaves underground. Even when winter comes the part of the plant underground lives while the plant above ground dies. Then when the next growing season the bulb underground makes new plants.

What is cutting?

“Cutting” is another way of growing a new plant. A part of the parent plant is cut off. For example, part of the stem would be cut off. Then this part would be planted to grow a new plant.

“Cutting” is like cloning a plant!

Starts as a seed, bulb, or cutting.

Begins to germinate by

growing roots.

The main shoot grows up, and

the plant starts to grow leaves for food from

the light.

The young plant uses its strong

roots to get more nutrients

and water.

The plant buds, making flowers

which make new seeds.

Life CycleLearn more about the life cycle!

Join the magic school bus in learning more about how plants grow!

Life Cycle You can draw your own life cycle too!

Learn more about why bees need plants and other animals that need plants.

1. Bees get food from plants to live.

2. Plants also need bees to help them grow.

So bees need plants, and plants need bees to live. This means that they depend on each other. Another name for bees and plants needing each other to live is interdependent relationships.

Bees need green plants to live AND green plants need bees to live!

Plants are not only to make the earth beautiful, but they also provide people with many things.

People use plants for air, fuel, clothing, food, shelter, and lots of other things.

Why do people need plants?

Unit Introduction Review

As a result the students have learned:– Green plants are plants with chlorophyll in them, the

chlorophyll is what makes them green.– Plants have stems, roots, leaves, flowers, fruits, and

seeds.– Plants make their food through photosynthesis.– In order to grow plants need room, air, water, nutrients

from proper soil, sun, the right temperature, and time. – Green plants can begin as either a seed, bulb, or cutting. – Seeds can drop from a plant or carried to be planted.

Seeds are tiny cases that hold a small plant and food.

Unit Introduction Review (Cont.)As a result the students have learned:– A bulb is underground structure that continues to produce new

plants above ground from the plant below ground.– “Cutting” is when a part of a plant is cut off and re-planted.

“Cutting” makes cloned plants.– The life cycle of plants begins with seed, bulb, or cutting. Then it

begins to germinate or grow by developing roots, the shoot grows up towards the sun making leaves which collects light, and then the plant produces new seeds to continue the cycle.

– Bees and plants depend on each other to live which is interdependent relationships.

– People also need plants for food, clothing, air, homes, paper, medicine, and number of other things.
