Cell signalling in plants is a process that allows cells to perceive environmental and endogenous cues, transmit this information, and trigger appropriate responses. The main stages of cell signalling are signal perception, signal transduction (including amplification and second messengers), and cellular response. Additionally, feedback regulation ensures fine control of signalling pathways.
1. Signal Perception (Reception)
Stimuli are detected by receptors, located in the plasma membrane, the

### 1. *What is a Script?*
* A script is the *blueprint of a film*.
* It tells the story in a way that animators, voice actors, and editors can follow.
* In animation, it’s even more important because everything — characters, settings, movements — must be created from scratch.
* A good script is *visual, clear, and expressive*, not just dialogue.

1. Adaptações Celulares
As células se adaptam a estímulos ou estresses para manterem sua função, mas, se falham, sofrem lesão.
* Hiperplasia: Aumento do número de células. É um processo de divisão celular que pode ser fisiológico (hormonal, como nas mamas e útero durante a gravidez) ou compensatório (regeneração, como na hepatectomia parcial do fígado). Pode ser também patológica, como em queloides ou na hiperplasia prostática benigna.

Terra nullius is a Latin term meaning "land belonging to no one," which was a legal principle used by European colonisers to claim sovereignty over inhabited territories, including Australia. Despite knowing there were indigenous people living in Australia, Britisher claimed Australia using the concept of Terra Tullius as justification as they felt as though the Aboriginal were not using he land ( lack of building, roads and infrastructure)
Defence issues played a significant role in the push for
Plant cell expansion is a turgor-driven process, where water uptake into the vacuole generates internal pressure. For the cell to enlarge, its cell wall must be extensible. This is tightly regulated by hormones especially auxin, the primary being Indole-3-acetic acid (IAA).
IAA promotes cell elongation particularly in young, growing tissues (e.g., coleoptiles, root tips) by modifying the mechanical properties of the cell wall.

Role of Indole-3-Acetic Acid (IAA) in Plant Cell Wall Expansion
Plant cell expansion is a turgor-driven increase in cell size that is constrained by the mechanical properties of the cell wall. Among phytohormones, Indole-3-Acetic Acid (IAA), the principal auxin, plays a central role in promoting cell elongation by modulating cell wall extensibility. The classical mechanism underlying this process is the acid growth hypothesis, which posits that IAA activates plasma membrane H⁺-ATPases, pumping
