THE PLANT KINGDOM
The plant kingdom is made up of a wide variety of many different species. Common features are laid out below.
They are multicellular, grow and develop throughout their lives, and have eukaryotic plant cells with a nucleus and organelles with membranes and a rigid cellulose structural layer: the cell wall.
- NUTRITION: The energy they need comes from the sun through photosynthesis and from certain chemical reactions.
- INTERACTION: They cannot move around, but some make certain movements and their seeds can travel far.
- REPRODUCTION: They can reproduce by asexual or sexual reproduction, or a combination of both.
PHOTOSYNTHESIS: is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
TYPES OF PLANTS
NON-FLOWERING AND SEEDLESS PLANTS
They have the following structures:
- RHIZOIDS: Short, thin filaments that anchor the plant.
- SETA: A stem-like axis that forms the central part of the plant.
- PHYLLODES: Leaf-like parts involved in capturing light and absorbing water.
They have three different parts:
- True roots: Which absorb substances and anchor the plant to the ground.
- Stems or rhizomes: Which grow underground.
- Large leaves, known as fronds.
