As water is vital to a plants survival, it is evident through this experiment that the fast plants had a greater growth in stem height as the water intake increased . The plants that received little to no water struggle to survive whilst the plants that received more water flourished and continued to grow in height.
What is the effect of watering plants on their growth height independent variable?
The independent variable should be the amount of water, because the height of the plant is not going to affect the amount of water . The dependent variable would be the height of the plant because it is relying on how much water is being added to it.
How does watering affect plant height?
Water helps a plant by transporting important nutrients through the plant. Nutrients are drawn from the soil and used by the plant. Without enough water in the cells, the plant will droop, so water helps a plant to stand upright. ... Too much water will affect plant growth just as much as too little .
What affects the height of a plant?
There are four primary factors that affect plant growth: light, water, temperature and nutrients . These four elements affect the plant's growth hormones, making the plant grow more quickly or more slowly. Changing any of the four can cause the plant stress which stunts or changes growth, or improves growth.
Does water make a plant grow taller?
Basics. Make plants grow taller by ensuring that their basic needs are being met. This includes water, sunlight, warmth and nutrients.
Do plants grow better in water or soil?
When they are just in water, they aren't exposed to as much sunlight as they would be if they were on land in soil, they don't get as much air, and they don't get the nutrients from the soil. Plants do grow in water , but they grow the best planted on land in soil where they can get soil, sunlight, water, and air.
How much water does a plant need per day?
Water use was not constant during the study; small plants used 1 tablespoon per day, while large plants used slightly less than 2 tablespoons per day . Overall, there was a good correlation between plant growth and the amount of water applied.
How does air affect plant growth?
Air is needed for the roots primarily to allow the plants to breathe . If air is not available to the roots, it can cause the roots to fail. ... When this happens, roots cannot absorb sufficient water and nutrients to the plant, causing yellow or brown leaves, plant stress and a reduced life span of the plant.
What effect does light have on plant growth?
Light intensity influences the manufacture of plant food, stem length, leaf color and flowering . Generally speaking, plants grown in low light tend to be spindly with light green leaves. A similar plant grown in very bright light tends to be shorter, better branches, and have larger, dark green leaves.
What variable is the height of the plants depends on?
The dependent variable is the height of the plant, because you predict that the height is going to change DEPENDING on how much water the plant receives.
What stimulates plant growth?
Auxins stimulate the elongation of cells in the plant stem and phototropism (the growth of plants toward light). ... Gibberellins promote both cell division and cell elongation, causing shoots to elongate so plants can grow taller and leaves can grow bigger. They also signal buds and seeds to begin growing in the spring.
Why are my plants growing tall and thin?
The most common cause of legginess is an insufficient or uneven access to light . When the light source is too dim or distant, seedlings grow quickly in height to get closer to that light. As the seedling gains height, it sacrifices in girth and strength, resulting in thin, pale, fragile, stretched-out stems.
What is the most important factor for plant growth?
Light is the most important ecological factor affecting plant growth. Light is necessary for photosynthesis, and changes in day length (photoperiod) regulate the phenological development of rangeland plants.
Does fertilizer make a plant grow taller?
Will plants grow taller when fertilizer is added each day? The experimenter hypothesized that fertilizer would make the plants grow taller. The results show that, on average, plants with fertilizer grew 0.7 cm taller over the course of 12 days .
How will water help the plants?
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. Too little water can cause a plant to wilt or droop.
