as plants use the gravitational pull for orientation. The roots of the plant grow into the soil (positive geotropism) in the direction of the gravitational pull of the Earth. The shoots of the plant grow in the opposite direction against gravity towards the light (negative geotropism‚ positive phototropism). Amyloplasts‚ which are non-pigmented organelle found in some plant cells‚ settle at the bottom of the cells of the shoots and roots in response to gravity‚ causing calcium signalling and the

Most plants do not do well with vinegar because it has a tendency to cause shock to the root system and can cause burns on the leaves. That is why getting the ratio amount is going to be huge. I do

Aquatic plants: Fixed plants Fixed plants are held in place by their roots which grow in the water-bed. The Water Lily and Lotus are such plants. Their stems are long‚ hollow and light. These stems reach the surface of the water. The leaves and flowers‚ which grow from the top end of the stems‚ float upon the water. The leaves are broad with stomata on the top surface so that the water does not block them. Lotus The roots of lotus are planted in the soil of the pond or river bottom‚ while the

Young‚ growing meristematic cauline tissue‚ apical root cells‚ young fruits‚ as well as unripe or germinating seeds are all rich in gibberellins. In sun flowers is the gibberellin content highest in the young leaves and in the uppermost internodes while it decreases continuously towards the basal leaves

Cloning is asexual reproduction. Cuttings are taken from a mother plant in vegatative growth‚ and rooted in hydroponic medium to be grown as a separate plant. The offspring will be plants that are identical to the parent plant. Cloning preserves the character of your favorite plant. Cloning can make an ocean of green out of a single plant‚ so it is a powerful tool for growing large crops‚ and will fill a closet quickly with your favorite genetics. When you find the plant you want to be your "buddy"

As stated in the video‚ morphology is the process to understand the words and how they work in a particular language. If we examine this definition‚ it’s clear that the root of every language is the word; therefore‚ if we want to truly understand a language we need to understand what a word is. The dictionary defines a word as “a sound or a combination of sounds‚ or its representation in writing or printing that symbolizes and communicates a meaning and may consist of a single morpheme or of a combination
