Biology of plants - observations of transplants and growth

In summary, there are several reasons for the observations mentioned in the conversation. In (a), wilting can be caused by damage to the roots, which can occur if the plant is not carefully dug up when transplanting. Both wilting and careless digging can harm the roots, leading to potential wilting after transplantation. In (b), removing some of the leaves before planting a cutting can help reduce the transpiration rate and allow for better water uptake. This is because the more leaves a plant has, the faster the transpiration rate for the same amount of water uptake. And in (c), plants in dry habitats have sunken stomata to retain water more easily during periods of high evaporation caused by wind. This helps them survive in

Homework Statement


Suggest reasons for each ofd the following observations:
a.When transplanting a small plant from a pot to the garden, it is importanat to dig it up carrfully, leaving the roots in a ball of soil. If this is not done the plant may wilt after it has been transplanted.

b. A plant cutting is more likely to grow successfully if you remove some of its leaves before planting it in compost.

c. Plants that live in very dry habitats often have stomata located in sunken pits in their leaves.

c) wind increase rate of evapo-transpiration, which happens via the stomata, sunken stomata means water is more easily retained

(a) what causes wilting? if you dig the plant up carelessly, what may happen to the roots? how are both answers related?

(b) hint: the more the leaves, the faster the transpiration rate for the same uptake of water.
 

1. What factors affect plant growth and development?

Plant growth and development is influenced by a variety of factors, including sunlight, water, nutrients, temperature, and soil composition. Different plant species may have specific requirements for these factors, and any imbalances or deficiencies can impact their growth and development.

2. How does transplanting affect the growth of a plant?

Transplanting can affect plant growth in several ways. It can cause temporary stress on the plant, leading to a decrease in growth initially. However, once the plant has acclimated to its new environment, it may experience a growth spurt. Transplanting can also disrupt the plant's root system, which can impact its ability to absorb nutrients and water, affecting its overall growth.

3. What are some common signs of plant stress?

Some common signs of plant stress include wilting, yellowing or browning leaves, stunted growth, and reduced flowering or fruit production. These symptoms can be caused by a variety of factors, including inadequate water or nutrients, extreme temperatures, pests or diseases, and transplant shock.

4. How can plant growth be measured and monitored?

Plant growth can be measured and monitored in various ways, such as tracking changes in height, leaf size, and number of leaves. Other methods include measuring the plant's biomass, which is the total weight of all its living components, or using specialized tools to measure the plant's photosynthetic rate or root growth.

5. How do plants adapt to changes in their environment?

Plants have several mechanisms for adapting to changes in their environment. For instance, they may change the orientation of their leaves to optimize sunlight absorption, or adjust their root system to access water and nutrients. They can also produce protective chemicals or adjust their growth rate in response to stressors such as extreme temperatures or drought.
