Peas How do they grow? ©Gwyneth Marsh 2007
Peas are the seeds of a plant. They grow inside pods. ©Gwyneth Marsh 2007
The pea seeds we use to grow pea plants are dry and hard, not like the soft, green ones we eat. pea seeds peas we eat ©Gwyneth Marsh 2007
The pea seeds germinate when they absorb water and become softer. A small root grows first, then a small shoot. Root Shoot ©Gwyneth Marsh 2007
The root grows first. It anchors the plant and absorbs water from the soil. The shoot can then grow into a seedling Pea seedlings ©Gwyneth Marsh 2007 ©Susan Johnson 2007
The pea plant is called a vine and has tendrils which help it to climb as it grows. Tendril ©Gwyneth Marsh 2007 Tendrils ©Susan Johnson 2007
Garden peas usually have white flowers. Bees may visit the flowers, but peas can self-pollinate. ©Gwyneth Marsh 2007
Once the pea flowers are pollinated the pods begin to grow. ©Gwyneth Marsh 2007
We harvest the peas to eat when the pods are fat and green. ©Gwyneth Marsh 2007
We can save seed to grow peas again next year. We must let the pods ripen and dry on the vine. We harvest them and take out the seeds. ©Gwyneth Marsh 2007
Pea moths Pea moths lay eggs in pea flowers and, as the pea pod swells, the grubs hatch and eat the peas inside the pod. © Susan Johnson 2007
Peas have nodules on their roots The nodules contain bacteria that take in nitrogen from the air and enrich the soil to help the plant grow. When the plant dies and decays nitrogen is also released into the soil. This process is important for organic growers who rotate their crops and keep the soil fertile without using chemical fertilisers. © Susan Johnson 2007 Nodule

Parts of a Plant by Denise Carroll. Living Things All living things grow and change. All living things need food, water, and air to live.
By: Group 4 Fifth Grade. ROOTS Roots hold a plant in the ground. They take in water and minerals from the soil. The roots of a plant are underground,
Plants. Parts of Plant ROOTS – take in water and mineral salts from the soil. They anchor the plant into the ground. STEM – is like a straw. It moves.
Life Processes Let’s look at living things. Living Things There are many different types of living things and they all look very different when compared.
Cycles in Nature Chapter 25, Section 2. Cycles of Matter The biosphere contains a fixed amount of water, carbon, nitrogen, oxygen, and other materials.
We will learn that plants produce flowers which have male and female organs. We will learn that seeds are formed when pollen from the male organ fertilises.
Soils Need Nutrients Too. KEEPING SOILS FIT Most soils have a large supply of nutrients. But when soils are continually used for growing food, nutrients.
Cycles of Matter. Cycles of Matter: Why? Because we have a fixed amount of STUFF (matter) on this planet, and no new stuff is being added from the universe.
