The potato does not increase in size because it is only a segment of the plant. Water absorbed from the soil is taken up by the roots and transported to other parts like leaves, but the potato itself does not directly absorb water from the soil.
2.775415722 The density is calculated as Mass divided by Volume.
Every cell is encased in a protective layer referred to as the cell membrane. In plants, an additional barrier known as the cell wall offers further protection. All organelles found within cells are enclosed structures.
Cell membranes consist of a phospholipid bilayer featuring both extrinsic and intrinsic proteins. Studies of the plasma membrane structure revealed that the protein patterns of MITOCHONDRIA and CHLOROPLAST are most akin to that of the cell membrane.
In eukaryotic cells, the nucleus is an enclosed structure by a membrane that holds the genetic information, which is activated when cells receive external signals (such as environmental changes). This genetic information consists of genes that respond to cellular signaling. For instance, transcription factors that reside in the cytoplasm become activated upon receiving signals from cell membrane receptors that bond with particular signaling molecules. Following this, those transcription factors move into the nucleus to engage with specific DNA promoter regions to initiate the transcription of target genes that can react to environmental stimuli.
