Vocabulary-

Roots-

  • The roots of a plant soak up vitamins and minerals.  

  • They hold the plant in the soil.

  • The are also where plants store their extra food.

 

Leaves-

  • The Leaves are where most of the food (sugar) for the plant is made.

  • They take in carbon dioxide and release oxygen into the air.

 

Pores- Tiny holes in the leaves that open and close

 

Stem-

  • The stem holds the plant up.

  • The stem has tubes that carry water, minerals, and food throughout the plant.

 

Flower- A flower is the part of a plant that makes seeds.

 

Fruit-

  • Fruits protect and hold the seeds of the plant.

  • Fruits are also eaten by animals which help the seeds spread to new places.

 

Vegetable- A stem, leaf, or root often eaten by animals.

 

Cell- the smallest unit of a plant or animal.

 

Nutrient- substances in the soil that help plants grow.

Photosynthesis- The process where plants make their own food.

Plants need carbon dioxide, water, nutrients, and energy from sunlight to make their food.

 

Chlorophyll- A green chemical in plants that helps them make their food during photosynthesis.

 

Sugar-The type of food that plants make in their leaves.  It is sometimes called glucose.

 

Oxygen- Oxygen is a type of gas that plants make (or produce) during photosynthesis.  

Carbon dioxide- A type of gas that plants need for photosynthesis. Animals produce carbon dioxide during respiration (breathing.)

 

Seed coat- a covering that protects the seed germ (baby plant inside a seed.)

 

Germination- When a seed begins to grow.

Most seeds need the following for germination to take place.

1- water (moisture)

2- the correct temperature

3- soil

 

Distribute- To scatter.  This can also be called DISPERSAL.

Seeds need to move away from the parent plant.  There are several ways seeds can be distributed;

1- by the wind

2- by water

3- animals (sticking to their fur, sometimes they bury them in the ground, or when animals eat the seeds and the seed passes through their bodies)
