Growth in plants occurs as the stems and roots lengthen. Some plants, especially those that are woody, also increase in thickness during their life span. The increase in length of the shoot and the root is referred to asprimary growth, and is the result of cell division in the shoot apica...

The mechanisms by which plants modulate their growth rate in response to environmental and developmental conditions are unknown, but are presumed to involve specialized regions called meristems where cell division is concentrated1,2,3,4,5. The possible role of cell division in influencing meristem ac...

In a biology experiment on the influence of different fertilizers on plant growth, when recording the growth data, we should ___. A. record only the height of the plants B. record the data once a month without looking at the plant condition C. record various data such as height, leaf ...
Salinity affects plant growth by ionic toxicity, osmotic stress, hormonal imbalance, the reduction in nutrient mobilization, and the production of reactive oxygen species (ROS) [2]. Therefore, salinity causes wilting, drying, and death of plants. Plants respond to salinity stress at different ...
