What is the life cycle and structure of a plant?

Understand the life cycle of a plant

Reference: SW9 Pg 121
Plants go through a life cycle like all other living things. There is no start or end to the cycle.

Seeds are dormant. What does this mean the seed is doing? Find out using the internet and write an answer in your own words.

Why would seeds need to be able to do this?

Plants are important because they provide food and oxygen but also because humans use them to make things with

Describe the structure and function of parts of the plant

There are two main systems in a plant:
The root system is below the ground
The shoot system is above the ground

Label the diagram of the plant:
Terms to use: Flower, Fruit, Leaf, Root, Stem.

What are the functions for each part of the plant numbered 1 to 5 in the diagram? 1. The leaf is made so that when the sun is out, it can photosynthesize to make food for the plant. 2. They bring water and nutrients from the roots and food in the form of glucose from the leaves to other plant parts. 3. The flower contains pollen and tiny eggs called ovules. After pollination of the flower and fertilization of the ovule, the ovule turns into a fruit. 4. The fruit is the outer protection for the seed a.k.a. an outer coating. 5. The roots absorb water and minerals that are in the ground. Tiny root hairs stick out of the root, helping in the absorption. Roots help to anchor the plant in the soil so that it does not fall over. Roots also store extra food for future use.

Describe the transport of water through a plant

Water is important for a plant. It needs water for:
photosynthesis
chemical reactions in its cells
support (to keep it upright and stiff)
keep leaves cool
Plants get water throughout their body by a process called transpiration.
