Parts of a Plant
This week in school we have been learning about Plants. The first thing we did was to identify the different parts and functions of a plant.
I have posted a picture of a labelled diagram of a plant. Can you write a description of the job of each part of the plant in your posts? You might want to carry out some extra research if you are not sure.

Petals - Petals are brightly coloured and sweetly scented part of a flower, and they attract bees and other insects. When the insects sit on the flower, hunting for nectar, the pollen grains stick to their legs. When they fly to the next flower, the sticky surface of the stigma catches the pollen, and this is how pollination mostly occurs. However, petals of some flowers do not need to be brightly coloured because they are pollinated by the wind instead of insects.
ReplyDeleteAnther - The anther is the part at the top of the stamen (the male part of the flower). The anther contains pollen, the yellow powder that is needed to make another plant.
Filament - The filament is the long stalk of the stamen that holds the anther up.
Stigma - The stigma is the part of the carpel (which is the female part of the flower). The stigma is covered in sticky substance that catches the pollen carried by insects or by the wind from another flower.
Style - The style is the stalk of the carpel that runs between the stigma and the ovary, and holds up the stigma.
Ovary - The ovary is the part of the carpel where the ovules (eggs) are stored. When the pollen grains get caught by the stigma, they travel down the filament and come into the ovary, where they join with the ovules and form seeds. This process is called fertilisation, and after this the ovary turns into the fruit.
Sepal - The sepals are special types of petal-like leaves at the base of a flower. They enclose and protect the delicate petals of the flower while it is still a bud, and they can be seen behind the petals after the flower has opened...ISHAAN
The petals are very colourful and very bright. Crystal
ReplyDeleteWhy do the petals need to be bright and colourful?
DeletePetals need to be colourful because it can atract the insects wich is nice
DeleteThe petals protect the flower if anything goes hard on it or anything like that . Crystal
ReplyDeleteParts of a plant
ReplyDeleteThere are 2 main parts of a plant, the male part called the Stamen and the female part called the Carpol. As you continue reading you will come to know what parts of a plant make up the Carpol and the Stamen.
Petals- Petals are modified leaves that surround the reproductive parts of flowers. They are often brightly colored or unusually shaped to attract pollinators. Together, all of the petals of a flower are called a corolla.
Sepals- A sepal is a part of flower of angiosperms , which are flowering plants. Collectively the sepals are called the calyx , the outermost whorl of parts that form a flower. Usually green, sepals typically function as protection for the flower in the bud, and often as support for the petals when in bloom.
Stigma- The stigma is the receptive tip of a carpel, or of several fused carpels, in is the female part of a flower. The stigma receives pollen at pollination and it is on the stigma that the pollen grain germinates.
Style- the Style is a slender, neck-like portion of the carpel that leads to the ovary, so it is a joining part like the stem which joins the plant’s roots to the plant’s flower.
Ovary-The Ovary is a enlarged basal portion of the pistil where ovules are produced. Later the ovules become seeds and the Ovary ripens into a fruit.

Receptacle-The receptacle is the axis (stem) to which the floral organs are attached. Floral organs are attached either in a low continuous spiral, as is common among primitive angiosperms, or in alternating successive whorls, as is found among most angiosperms.
Staminode-In many angiosperms, one or more of the stamens is modified and lacks functional anthers. In the most common modification, the filament is expanded to form a petallike blade called a staminode (in the same manner that a sepal forms a petallike blade in some flowers without true petals). The apparent petals in some angiosperm families, such as are found in many members of the pink...
I like that you have done some of your own research on this. Please check your spelling of Carpel.
DeleteAlways make sure that when you carry out your own research you try and write it all up in your own words.
I will remember if I can
