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.
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
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.
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.
Link to interactive game about Photosynthesis-
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
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)
