PLANTS

SC-04-3.4.1

• Each plant or animal has structures that serve different functions in growth, survival, and reproduction.

SC-04-3.4.3

• Plants and animals have life cycles that include the beginning of life, growth and development, reproduction and death.

Ideas

• Plants are made up of different parts. Each part has a certain job. These parts can also help us to identify plants.

• There are seven basic requirements that plants need in order to grow properly.

Plant Basic Needs

• Room to grow

• Temperature

• Light

• Water

• Carbon dioxide (air)

• Nutrients

• Time

Vocabulary

• Plant Structures – “parts of the plant”– Ex. Leaves, root, stem, flower, seeds, fruit

• Leaves – help the plant make food through a process known as photosynthesis.

• Root – help hold the plant in place and take in water and nutrients the plant needs.

• Stem – supports or holds up the plant.• Flower – helps the plant reproduce.• Seeds – are made from flowers when plants

reproduce.• Fruit – the edible part of a plant which contains

seeds.

Plant Structures

• Roots

• Stems

• Leaves

• Flowers

• Fruits

• Seeds

Roots

Roots Functions

• Most roots grow in soil or water.

• The roots hold the plant in the ground.

• A plant uses its roots to get water.

• The water goes through the roots into the plant.

• Some roots that we eat are: carrots, beets, turnips, radishes, and sweet potatoes.

Stems

Stem Functions

• The stem is the part of a plant between the roots and the leaves.

• The stem holds up the plant. 

• The stem also carries water and food through the stem to the plant.

• Some stems that we eat are: celery, broccoli, asparagus, white potatoes, and sugar cane.

Leaves

Leaf Functions

• A leaf grows on the stem or branch of a plant.

• A green plant makes food in its leaves through a process known as photosynthesis.  

• The leaf  has tiny holes that let water vapor and air pass through.  

• The leaves need sunlight, air, and water to make the food for the plant. 

• Some leaves that we eat are: lettuce, brussel sprouts, spinach, and parsley.

Fruit and Seeds

Fruit and Seed Functions

• Seeds are made from flowers.

• Many plants grow from seeds.

• Fruits hold seeds. • Some fruits that we

Flowers

Structures of a flower

• Petal – Surrounds the male and female parts and is brightly colored to attract insects which help pollinate the flower.

• Stamen – The male part of the flower which produces pollen.

• Pistil – The female part of the flower which contains the seeds.

• Ovary – The part of the pistil which holds the flower’s seeds.

• Pollen – The yellowish powdery substance on the stamen used to fertilize the plant.

• Seeds – Found inside the ovary.

Structures of a Flower

Flower Functions

• Flowers grow on the stem of plants.

• Flowers make seeds.  Many plants grow from seeds.  

• Flowers make fruits.  Fruits hold the seeds of the plant.

Lets see what you learned…

• Draw a plant. Label its structures.• Explain the function of each structure. Don’t

forget to tell how the function contributes to the growth, survival, or reproduction of the plant.

• Draw a flower. Label its structures.• Explain the function of each structure. Don’t

forget to tell how the function contributes to the growth, survival, or reproduction of the plant.
