By Rebecca Plants come in many shapes, sizes and colours. TASK 1. Take a look outside, how many plants can you see? Different types of plant grow in different places all around the world! In this presentation, I hope to show you exactly what plants are. •Carpel - consists of the stigma, style, and ovary. •Stigma - the tip of the carpel that is sticky in order to collect pollen •Style - the slender, neck-like portion of the carpel that leads to the ovary. •Ovary - structure at the base of the carpel that houses the ovule or egg. Here are the main organs of a flowering plant, they are not in order of importance. If a flower was missing any on of these it would make life -nearly •Sepal green, leaf-like structure that impossible! protects the budding flower. •Petal - colourful and often scented part of the flower that attracts insects •Stamen - the part of the flower that produces pollen. Consists of a filament and an anther. •Anther - sac located at the tip of the filament that contains pollen. •Filament - stalk that connects to and holds up the anther.

Non-flowering: nonflowering means that a plant will never produce flowers! As you can see in the pictures! Monocotyledons make a seed with a seed coat. Inside the seed there is plant embryo with a primitive root and a supply of food for the new plant. The food supply is called the endosperm, and it is all in one piece. When the little plant comes out, the root goes down and a single spire goes up. The young plant uses the food resources of the endosperm to provide energy for growth. The endosperm part (the inside of the corn kernel in our example) is the single seed leaf: the monocotyledon The parent plant has stored food in this kernel so that the young plant will have energy resources that it can use to start building itself up as the seed germinates Dicotyledon seeds also contain an embryo plant. The seed is protected by a seed coat. There are two seed leaves inside the diocotyledon seed. The seed leaves nourish the plant after it germinates. Germinating diocotyledon plants all look very There similar are other to differences between this picture when they first begin to grow. The these two two seed families of angiosperms, leaves open and the shoot of the plant's characteristic but the differences shown here leaves grows up between them. should be enough to help you to identify the groups that plants belong Diocotyledon leaves are net-veined. Study the pictures of in. the yellow primroses here to see how their leaves have veins that go down the leaves and also across them. that coniferous trees are Remember gymnosperms. Coniferous trees do The flowers of dicotyledons have petals and other flower not belong to the angiosperm family. parts arranged in fours and fives, or in multiples of four They come from a much more ancient and five. Roses have five petals. Cherry blossoms have lineage. They invented the seed a five petals. Our fruit trees and deciduous trees are long time ago. diocotyledons, as are many shrubs and flowers. Perennial plants are plants which will continue growing year after year, rather than dying off after a season or a year like annuals do. There are a number of different kinds of perennial plants, with gardeners using perennials as permanent fixtures in their gardens. Gardening stores and nurseries typically stock a range of perennial options, most of which are suitable for the climate the store is located in, and it is also possible to order specific perennials.
