Which part of plant grows into stem?
Plant stems, whether above or below ground, are characterized by the presence of nodes and internodes (Figure 1). Nodes are points of attachment for leaves, aerial roots, and flowers. The stem region between two nodes is called an internode. The stalk that extends from the stem to the base of the leaf is the petiole.
Where does stem develop from?
The stem and other plant organs arise from the ground tissue, and are primarily made up of simple tissues formed from three types of cells: parenchyma, collenchyma, and sclerenchyma cells. Parenchyma cells are the most common plant cells (Figure 2).
Which part of the plant grows from the seed?
Seeds have a seed coat which protects them while they grow and develop, usually underground. Inside the seed there are is an embryo (the baby plant) and cotyledons. When the seed begins to grow, one part of the embryo becomes the plant while the other part becomes the root of the plant.
Do seed plants have stems?
1.1 The Seed Plant Body Seed plants have only three organs, and you already know them. They are leaves, stems, and roots (Figure 1.2). These organs in turn are made up of tissues that are much simpler in comparison with those found in vertebrate animals.
What are parts of stem?
A typical plant stem consists of eight distinct parts, containing six elements and two organs. The six elements are: 1) nodes, 2) internodes, 3) terminal or apical bud, 4) lateral or axillary bud, 5) petiole and 6) pedicel. While the two organs are: 7) leaves and 8) flowers.

Which is part of a stem?
The stem is composed of three tissue systems that include the epidermis, vascular, and ground tissues, all of which are made from the simple cell types.. The xylem and phloem carry water and nutrients up and down the length of the stem and are arranged in distinct strands called vascular bundles.
Do stems produce food for the plant?
stem, in botany, the plant axis that bears buds and shoots with leaves and, at its basal end, roots. The stem conducts water, minerals, and food to other parts of the plant; it may also store food, and green stems themselves produce food.
Where do seeds come from?
Once the pollen grain has stuck to the stigma of the second flower, a pollen tube grows through the style of the carpel until it reaches the ovary which contains ovules. Fertilisation takes place when the pollen grain joins together with an ovule in the ovary. The fertilised ovule will then become a seed.
What are the examples of STEM?
The definition of a stem is the main stalk of a plant. An example of stem is the part that holds up the petals on a flower and from which the leaves grow. Stem is defined as to originate from. An example of stem is when an argument arises from a previous statement.
What is a stem strand?
