A plant is a living thing thing that makes food on its own. A plant has a stem, leaves and roots. A plant is a system. A plant can make food. Some plants are poisonous but some are not. Examples of plants with poisonous parts are dumbcane and pong pong tree. Some plants have woody stems but some do not. Examples of plants with woody stems are yellow flame and hibiscus. Balsam plants have non-woody stems. Plants can make food as well as grow.Different kinds of plants have different ways of reproducing. Some plant have weak stems. Examples are tomato plant,spartina patens and kerria plant. Some plants live in water while some live on land. All plants need food. They make their own food. Stomata of the leaves are usually found on the underside of leaves, away from the sunlight so as to prevent water inside the plant from evaporating through the stomata. Air passes in and out of the leaf through these stomata. In a plants stem there is something called the xylem (The xylem, the water-carrying tube, is the part of the plant which the water and nutrients are carried up.) and phloem. The phloem transport food from the leaves around the plant.
 * How does water travel up the stem of a plant?**

Plants are living organisms. They include familiar organisms such as trees, herbs, bushes, grasses, vines, ferns, mosses, and green algae. The scientific study of plants, known as botany, has identified about 350,000 extant species of plants, defined as seed plants, bryophytes, ferns and fern allies. Some plants reproduce by suckers, fruits ,spores or leaves.

During photosynthesis (there is sunlight), the plant gives out oxygen and takes in carbon dioxide but during respiration (no sunlight) , the plant gives out carbon dioxide and takes in oxygen like us , human beings. Plants are [|__living__] [|__organisms__] belonging to the [|__kingdom__] Plantae. Plants respire eveytime and a another word for make food is photosynthesis.

When plants photosynthesis, they give out oxygen and take in carbon dioxide through the stomata found in the leaves while they take in oxygen and give out carbon dioxide when they respire.

Green plants have cell walls with cellulose and characteristically obtain most of their energy from sunlight via photosynthesis.

A leave cell of a plant has chloroplast as it need chloroplast make food while a root cell of a plant doesn't as it does not make food.

The Phloem tubes carries water in two ways. There may be leaves up the plant for the lower leaf to give food to. The Xylem only contains water that is carried to the leaves in one direction as the roots of the plant is always beneath the plant.

//Green leaves often have yellow pigment that is covered up by the green pigment colour untill fall, when the green starts to fade that is when the leaves change colours.// //Plants transport water through xylem and transport food through phloem.//

Before a seedling has leaves, food is obtained from food stored in its seed leaves.

Water and minerals flow upward through the roots into the stem of the plant and then into the leaves of the plant.

In plants the water moves in one direction.

Leaves' chlorophyll trap sunlight to make food

The roots of a plant help to hold the plant up and bring in food and water from the soil.

A plant is a living thing which plays a very important part in the food chain.
