Plants Basic


What are plants? Plants are living multicellular organism. Plants can be consider has the source of life on our planet. They are from the kingdom Plantae.

Plants produce food by a process called photosynthesis. Photosynthesis is the process by which plants convert light energy, water (H2O) and carbon dioxide (CO2) into carbohydrates and oxygen. The food produced by plants is consumed by other organisms, thus making plants the primary producer of food for the world. If plants should stop producing food, most organisms in the world would die (including humans). Plants also provides the world with oxygen, which is needed to sustain life on earth.

Most plants are vascular meaning that they are able to transport nutrients inside of themselves. Some plants are not vascular such as algae. It’s important to note that most vascular plants are seed plant. The two main types of seed plants are gymnosperms and angiosperms.

The three main types of plants tissue system:

1. Dermal Tissue System which consists of the epidermis and the periderm. Dermal tissue system offer protection to the plant and prevent water loss.

2. Ground Tissue System makes organic compounds, supports the plant and provides storage for the plant. Ground tissue system is comprise of parenchyma tissue, collenchyma tissue and sclerenchyma tissue. The ground tissue system function is to store food, support the plant, regeneration and photosynthesis.

3. Vascular Tissue System is made up of xylem tissue and phloem tissue. Its function is to transport water and minerals around the plant. And also to transport food.

Flowering Plants

Flowering plants are classified base on the number of cotyledons they display. Flowering plants can be monocotyledons (one cotyledon) or dicotyledons (two cotyledons)

This post only provides basic information on plants. Please visit video link below from YouTube to gain more knowledge. Please watch the video about plant cells.

Plants basic needs are listed below:

1. light (sunlight preferably)

2. Air

3. Nutrients and mineral source

Plants also need a medium to survive. But the kind of medium requires differ from specie to specie (e.g. soil)
