Meristem size is a very controled, highly genetic feature. It doesn't change between big or small branch/root (The SAM and RAM are obviously different). There are very levels of potency in the meristematic tissue, so you should explain more which section of the meristem is of interest. SAM (shoot apical meristem) In *Arabidopsis thaliana* there are 9 long-...

Since you asked for the science I'll try to give a scientific but simple explanation. Trees (and plants) become wider and taller over time. This growth is due to cell division and cell elongation from meristematic cells (analog to stem cells in animals). The stem (upper part of a plant) becomes wider because is it constantly creating new vascular tissue from ...

I add an answer since Andrew's answer "Do all plant cells that die do it while fullfiling a function" and the question asks wheater all plants cells that die to fulfill a function have a secondary wall. Hyper-virulence response is a plant defence mechanism from pathogenes similar to "scortched earth" strategy. The plant kills all cells ...

Mold is a general name for many species of Fungi, which are heterotroph so they need organic material to feed on. You can see them grow on fiberglass because many organic material can accumulate near or on fiberglass (skin cells, plants root hairs, microbes, oils) and become substrate for the mold. If you want to grow a specific mold you should first ...

The heat the plant produces ultimately comes from the light it uses. Unless the plant produces heat just in the wanted time (winter?) from light absorbed another time; then you would be just as warm by letting the light directly warm your environment regardless of plants.

Philodendron bipinnatifidum is a thermogenic houseplant. It is somewhat toxic, so not pet- or small-child-friendly, but commonly grown as a houseplant. However, I do not know if the heat generated would be enough to significantly impact your house; my impression is that most thermogenic plants merely warm their immediate surroundings (so you may need a LOT ...

Not all plant cells perform a function when they die. But a lot do. Sclerenchyma is refereed to as: Sclerenchyma is the tissue which makes the plant hard and stiff... Mature sclerenchyma is composed of dead cells with extremely thick cell walls (secondary walls). Plant cell death includes necrosis, apoptosis and autophagy and studying how and why they ...
