Questions and Hypothesis: Seed germination‚ plant growth‚ and sprouting of leaves are affected by several factors: supply of nutrients‚ water‚ exposure to sunlight‚ and conditions of surroundings. Due to certain stimuli in the surroundings plant “hormones” cause plants to behave in ways that ensure the most efficient use of resources while preserving the most energy. One stimulus to consider‚ is the exposure of plants to sunlight; when plants are just sprouting and are underground‚ the sti

He sees The Tollund Man as a timid victim of circumstances and feels sorry for him and his plight.

ABSTRACT Making use of radish extract as an effective alternative method of getting rid of insects and pests like worms‚ ants‚ and aphids was studied in this research project. The purpose of this experiment is to prove that radish extract can be used as an insecticide. The researchers first gathered all the materials needed to complete the experimentation. First washed‚ sliced‚ and pounded the radish tubers using the mortar and pestle. Then the researchers extracted it by using

flowering plants show sexual reproduction. A look at the diversity of structures of the inflorescences‚ flowers and floral parts‚ shows an amazing range of adaptations to ensure formation of the end products of sexual reproduction‚ the fruits and seeds. In this chapter‚ let us understand the morphology‚ structure and the processes of sexual reproduction in flowering plants (angiosperms). 2.1 FLOWER – A FASCINATING ORGAN OF ANGIOSPERMS Human beings have had an intimate relationship with flowers

include in phylum Anthophyta.Angiosperms are plant that have flowers and fruit. Their part of the flower is a carpel which surrounds and protects the ovules and seeds. The fruit surrounds the embryo and aids seed dispersal. The great majority of angiosperms are classified either as monocots or eudicots.Monocot embryos have a single seed leaf (cotyledon)‚ and pollen grains with a single groove while eudicots (true dicots) have two cotyledons‚ and pollen grains with three groove. Monocotyledons have

ALMONDS IN WATER BEFORE CONSUMING? Dry almonds contain an enzyme inhibitor in the skin which is basically meant to protect the seed till it gets moisture for germination. When the almonds are soaked in water this enzyme inhibitor is released. Eating pre-soaked almonds is easier to digest and also makes more nutrients available for digestion. In fact‚ most nuts and seeds are easier to digest and have better nutrient availability
