This question is asking us about cell types in plants.
00:04
And the question is asking is which type of cell make up fibers in the stems of plants? and the answer is that these are made up of sclerancoma.
00:24
Not an easy word to say, sclerencoma.
00:30
And these are cells with thick cell walls, and they are dead at maturity.
00:43
So fibers are made up of sclerancoma, and the answer then is letter b.
00:54
The other types of cells play different roles in plants.
00:59
For example, perencoma is a very common type of cell, one of the most common types of cells in plants, and among other things that's involved in storage of, say, starch in root cells, and it's also involved in photosynthesis, in leaves.
01:24
So it's a very versatile type of cell.
01:33
There's also colankhama, and colankema cells are typically structural or support cells.
01:45
So you find them in the stem, and they help support the stem, and they help hold the plant upright...
