Answer:
While plant cells have chloroplasts to photosynthesize, they also require ATP for cellular functions, and do use oxygen to break down some of the sugar they produce in order to generate that ATP. They need mitochondria for this.
In particular, at night when there is no light, plants undergo cellular respiration since there is no sunlight to photosynthesize.
They do, however, produce far more sugar and oxygen through photosynthesis than they use up in respiration.
If all other resources are in adequate supply, then the light intensity will increase the rate of photosynthesis. To balance it out, other things then usually start becoming short in supply, so things often don't change.
The plant cells communicate across cell walls through Plasmodesmata.
how do plant cells communicate across cell walls?
- Between tiny channels woven through the walls of neighboring plant cells, plant cells can communicate with one another through channels referred to as plasmodesmata.
- These channels enable chemicals to move freely between cells, allowing plants to grow regularly and form tissues and organs.
- However, plasmodesmata also act as entryways that viruses can employ to infect an increasing number of cells.
- Given these advantages and disadvantages, plants must balance the permeability of their plasmodesmata in order to move materials from one cell to another while preventing the spread of infection.
