What are the limitations of cell growth?

Answer 1

Assuming "cell growth" refers to cell size, the size of a cell is often limited by the amount of surface area of its plasma membrane in relation to the cell's volume. The plasma membrane is the outermost membrane on a cell--the one through which all substances must pass either entering or leaving the cell. As the cell gets larger, the amount of plasma membrane becomes too small to allow sufficient quantities of necessary substances, such as food or oxygen to enter the cell in a timely manner. Likewise, there is not enough available surface for the cell to rid itself of wastes (carbon dioxide, for example), so the cell has three options: 1 keep growing and die 2 stop growing and 3 divide into two smaller cells.

Answer 2

It depends on the situation, however it will most probably be either:

-Temperature

-Light

-Carbon Dioxide Levels

or..

-Waters levels

For example, a wheat field first thing in the morning's limiting factor would be temperature because it will have some light, plenty of carbon dioxide as it has not used any during the night (due to a lack of light in photosynthesis), however, the morning is quite often the coldest part of the day, so all of the reactions will be slower, producing less food for the plant.

Answer 3

Limitations of cell growth include availability of nutrients, space for expansion, accumulation of waste products, and reaching the Hayflick limit for cell division. These factors can contribute to cell cycle arrest or cell death.

Answer 4

Supply of essential plant nutrients, water, sun shine and good quality of air.

Answer 5

Plant growth can be limited in a variety of ways. These limiting factors include: nutrients, water supply, temperature, sunlight and soil composition.

Answer 6

• water
• sunlight
• shade
• food

Answer 7

The average value and annual variation of temperature and moist (precipitation).

Answer 8

It has to do with Harry and Bob
