What is a plant?

• A plant is a living organism of the kind exemplified by trees, shrubs, herbs, grasses, ferns, and mosses, typically growing in a permanent site, absorbing water and inorganic substances through its roots, and synthesizing nutrients in its leaves by photosynthesis using the green pigment chlorophyll.
• 

PARTS OF A PLANT

• The main parts of a plant include:
• Roots
• Stem
• Leaves
• Flowers
• Fruits
• 

Description . Parts of a plant

• Roots
• They are the major part that anchors the plant firmly in the soil. They absorb water and minerals from the soil, synthesise plant growth regulators, and store reserve food material.
• Stems
• Stems arise from the plumule, vertically upwards to the ground. The stem provides support to the plant. They also protect the plant and help in vegetative propagation.
• Leaves
• Leaves are the most important part of a plant. They contain chlorophyll that helps the plants to prepare their food using sunlight, carbon dioxide and water.
• Flowers
• They are the most beautiful and colourful part of a plant. They are the reproductive part of a plant.
• Fruits
• Fruits are the main features of a flowering plant. It is a matured ovary that develops after fertilisation.

CYCLE OF A PLANT

• Bildunterschrift: Cycle of life

Description about cycle of a plant

• Seed
• Seeds are much like babies of the plants. Seeds contain the embryo of the plants with necessary food and an outer coating for protection.
• Germination and seedling
• When the conditions in the soil are just right, the seed germinates. First, it breaks the outer coating and begins growing its first roots and leaves.
• When the first sign of life from a seed appears out of the soil, it is called seedling
• Growing to maturity
• The seedling continues to grow to its full maturity. The plant needs many necessary things during its growth . When plants become mature, they have to get stronger roots and an increased number of branches and leaves. At this stage, they are ready to make flowers and new seeds.
• Flowering, pollinating and seeding
• When plants become mature, they start to make flowers and pollen. When the pollen reaches the female part (ovary) of the flower, it fertilizes the cells inside it and produces seeds.
• Repeating the cycle

PLANT NEEDS

• Almost all plants need these five things to survive:
• Light: Plants use light energy to make a type of sugar called glucose. They use glucose as their energy source.
• Air: It contains many gases. They include nitrogen, oxygen, carbon dioxide and water vapour. Using energy from light, plants chemically combine carbon dioxide and water to create glucose and oxygen. This process is called photosynthesis.
• Water: Plants need water for photosynthesis. Absorbed by the roots, water travels through a plant’s stems to the chloroplasts in the leaves. Water also helps move nutrients from the soil into the plant.
• Nutrients: are substances that nourish a plant. In particular, plants need nitrogen, phosphorus and potassium. When dissolved in water, these nutrients get absorbed by a plant’s roots.
• Space to grow: A plant’s roots need space so that they can spread out and absorb water and nutrients. Its leaves need space so that they access light.
• 

PLANT FUNCTIONS

• Plants give us:
• Oxygen.
• Fruits
• Vegetables
• Grains
• Seeds
• Habitat for insects, bees, butterflies.
• Flowers for garlands, decor and extracting essence to make soaps, perfumes.
• Edible roots.
• Edible leaves like better nut.
• Leaves to be used as disposable plates. Eg. Banana leaves.
• Medicinal herbs.
• Oil.

TYPES OF PLANTS

• There are many ways botanist, or plant scientists, classify, or group, plants. The four main types of plants are
• 

Descriptions about types of plants

• Mosses and worts:
• Mosses and worts are low-growing, nonvascular plants. Since they don’t have the vascular system that allows water to travel long distances, these types of plants don’t grow very tall.
• Liverworts and hornworts
• These are the simplest type of all plants. Liverworts and hornworts don’t have roots.
• They grow in flat leaf-like structures on the ground.
• They have rhizoids , or tiny hairs, on them.
• Ferns
• Ferns are a type of vascular plants that reproduces by spores. Since they have a type of circulatory system, they can grow taller than mosses and worts.
• Gymnosperms
• These are vascular plants that reproduce through seeds. The seeds of gymnosperms grow inside cones

IMPORTANCE OF PLANTS

• Benefits of the plants
• Plants are really important for the planet and for all living things.
• Plants absorb carbon dioxide and release oxygen from their leaves, which humans and other animals need to breathe.
• Living things need plants to live - they eat them and live in them.
• Plants help to clean water too
