5º. Unit 4.THE PLANT KINGDOM
The Plantae Kingdom is made up of all the plants that you see each day.
Most plants are multi-cellular, meaning that they consist of many cells.
Different types of plants include trees, grass, flowers, and some types
of algae.
Plants use the light from the Sun to produce their own food. This allows
them to grow almost anywhere, as long as there is enough water.
Plants get their green color from the chlorophyll which is found inside
of their cells. Plants use chlorophyll to collect energy from the light
of the Sun. They then use this energy to create food. In this process,
they create the food we eat and the oxygen we need to breathe. Plants
are very important to the life of almost every other living thing.
Flowering Plants
Flowering
plants at the adult stage, the plant produces flowers which can develop into
fruits and seeds after being pollinated and fertilized. Rose, hibiscus,
sunflower, mango, mango, banana, and papaya are flowering plants. The scientific name
for flowering plants is Angiosperms.
This is the most abundant and widespread group of plants on Earth.
Flowering plants are found in most habitats, from deserts to polar
regions, and include species of trees, shrubs, and herbs. The flowers
are the reproductive structures that produce new plants.
Angiosperms are plants that are seed-bearing. Their reproductive structures are flowers were the ovules are enclosed in an ovary. Angiosperms can found in most habitats from forests, grasslands, sea margins and even deserts. The leaves of an angiosperms are flat. Examples of Angiosperms are grass, Apples, Oranges and Bananas.
Gymnosperms are seed-bearing plants, such as conifers fir trees, pine trees,The ovules or seeds are not enclosed in an ovary. Gymnosperms are plants that the seeds are exposed.
Non-flowering plants
Non- flowering plants do not carry flowers they produce spores, fungi or cones the are used for propagation (reproduction). Algae, moss, fern and conifer are no flowering plants.
There are some non-flowering plants that don't produce seeds. Instead, they use spores to reproduce. Spore producing plants include plants such as mosses and ferns. Spores are tiny organisms that usually contain only a single cell. Plants that make spores produce huge numbers of them. Because they are so small and light, they can be dispersed by the wind to new locations where they can grow.
