placed end to end that form tunnels through which water and minerals move upward from the roots (where they are taken in) to the rest of the plant. Phloem‚ which is made up of living cells‚ carries the products of photosynthesis (organic nutrients) from the leaves to the other parts. The vascular system is continuous throughout the whole plant‚ even though the xylem and phloem are often arranged differently in the root than they are in the shoot. The major mechanism by which water (along with dissolved

As the radicle grows downward‚ the cotyledons form the plumule‚ which contains the stem and first leaves of the tomato plant. Tomatoes respond well to warm temperatures. The minimum temperature for seed germination is 10°C with a maximum temperature of 35°C and an optimum range of 17°C to 20°C. 2) Roots: a) Primary Root: to anchor the plant to a substrate‚ to absorb water

In several types of plants‚ asexual propagation is the fastest means of new plant growth. Asexual propagation is also a good way to maintain a plant species because they are genetically identical. In this process‚ adventitious roots are seen in the growing cycle. Adventitious roots are those that grow form parts

Introduction: The purpose of the plant growth experiment was to test the affect of plant fertilizer during plant growth. The system we were working with allowed us to test the recommended amount and double the recommended amount of Miracle Grow in comparison to a control of an all natural growing plant. The plants we were testing were radishes We decided on testing the validity of Miracle Grow with radishes to determine if fertilizers are worth purchasing. Hypothesis: If the recommended amount

These excretions were first brought up somewhere around the mid eighties and have discrepancy to whether or not they exist still today. Some people that
