Reproduction in plants

• The seeds of coconut have an outer fibrous or spongy covering . This enables them to float in water and dispersed through water.
• Seed dispersal enables the plants to invade new habitats for wider distribution.
• Vegetative propagation is the process of reproduction in which new plants are produced from different parts of old plants like stem, roots or leaves.
• In vegetative propagation, there is no need for pollination as it does not involve sexual reproduction
• Vegetative propagation is used when we want to produce many identical copies of one parent plant.
• Vegetative propagation can be done by cutting off part of plant and replanting it into soil.
• Pollination is the transfer of pollen grains from the stamen to the pistil.
• Cutting and grafting methods are two methods where the stem is used for vegetative propagation.
• Sugarcane and rose are two plants cultivated using vegetative propagation. This is an asexual method of reproduction.
• Colorful whorl of the flower is petals
• D) Male reproductive organ of the flower is stamen
• E) The part of the female reproductive organ of the flower where ovules are present is ovary
• Seeds with spines are dispersed by humans and animals.
• Anther and filament are the male sex organ
• Pollen tube grows down through the style into the ovary and fertilizes the egg cell inside one of the ovules.
• Ovule, style and stigma are the female sex organs
• A seed contains an embryo (a young plant), stored food reserves, and a protective coat called the testa or seed coat.
• A zygote develops into an embryo.
• The cotyledon stores food reserves such as carbohydrates and proteins.
• The root hair absorbs water from soil.
