Cell theory is one of the foundations of biology. The observation of Robert Hooke,Anton Van Leeuewenhoek,Matthias Schleiden,Theodor Schwann,Rudolf Virchow, and others led to the devolepment of the cell theory.
<h3><u>Answer;</u></h3>
Plasmodesmota
<h3><u>Explanation</u>;</h3>
- Plasmodesmata type of cell junction in plant cells that are cytoplasmic channels that perforate cell walls to connect adjacent cells.
- The cytoplasm of one plant cell is continuous with the cytoplasm of its neighbors via plasmodesmata. Unify most of the plant into one living continuum.
- The plasma membrane of adjacent cells line the channels of the plasmodesmata and thus are continuous, letting water and small solutes pass freely from cell to cell, and sometimes certain proteins and RNA.
Answer:
Somatic
Explanation:
The somatic sensory system consist of sensory neurons and the neural pathways that produce response to the changes inside or at the surface of the body. The axons of sensory neurons connects and provide response to receptor cells.
The sensory neuron that generate response to a particular stimuli is named with the kind of stimuli, for example - heat stimulus activates the thermoreceptor that detects the temperature changes.
The other receptors like mechanoreceptor that respond to mechanical pressure, pain receptors respond to painful stimulus, chemoreceptors that respond to chemical changes and nociceptors that respond to threat stimulus are the part of somatic sensory system.
