Several organisms have the remarkable ability to change their shape. This ability is often referred to as "shape-shifting" or "morphological plasticity." Here are some examples of organisms from various taxonomic groups that can change their shape:
Amoebae (e.g., Amoeba proteus): Amoebae are single-celled protists known for their shape-changing abilities, enabled by pseudopodia, temporary cytoplasmic extensions they use for movement and capturing food.
Cephalopods (e.g., octopuses, squids, and cuttlefish): Cephalopods are highly intelligent marine animals. They have soft bodies and can rapidly alter the texture, color, and shape of their skin to blend in with their surroundings and communicate with other individuals.
Flatworms (e.g., planarians): Flatworms are simple, bilaterally symmetrical animals that possess regenerative abilities. They can alter their body shape and regenerate lost body parts.
Tardigrades (water bears): Tardigrades are micro-animals known for their extreme resilience. They can undergo a process called cryptobiosis, where they lose almost all water content and shrink into a tun-like shape, surviving extreme conditions.
Slime molds (e.g., Physarum polycephalum): Slime molds are unique organisms that can change their shape to optimize nutrient absorption. They exhibit complex behavior despite being single-celled during some stages of their life cycle.
Sea cucumbers: Sea cucumbers are echinoderms that can change their body shape dramatically by contracting their body wall muscles or expelling their internal organs as a defense mechanism.
Bacteria (e.g., Escherichia coli): Some bacteria, like Escherichia coli, can change shape based on environmental conditions. For example, they can shift from a rod-like shape to a spherical shape under certain stresses.
Hydra: Hydras are small, simple, freshwater animals capable of changing their body shape during feeding and locomotion.
Proteus anguinus (olm or cave salamander): The olm is a blind, aquatic salamander known for its adaptability and ability to change its body shape based on the environment and feeding habits.
Flowering plants (e.g., Mimosa pudica, Venus flytrap): Some plants can undergo rapid shape changes in response to stimuli. For instance, the sensitive plant (Mimosa pudica) folds its leaves when touched, and the Venus flytrap (Dionaea muscipula) snaps its trap shut when triggered by an insect.
These examples highlight the diversity of organisms that possess the ability to change their shape, either as a part of their natural behavior or in response to environmental cues. The ability to alter shape plays a crucial role in their survival, feeding strategies, and defense mechanisms.

Mold
It is a physical change unless it is caught on fire to mold into a different shape then it would be a chemical change. The substance that does change shape does not develop new chemical properties.
Gases can NOT change shape because gases don't have a 'shape', it's the container in which they are held that has a shape)
Yes, a solid shape can change. If the heat rises above a certain temperature that which a solid can handle (the melting point) than the solid begins a physical change into a liquid.
Amoebas are unicellular organisms that can change their shape constantly by extending and retracting pseudopods, which are temporary bulges of the cell membrane. This shape-shifting ability enables amoebas to move and engulf food particles for consumption.

The word "amoeba" is Latin in origin, derived from the Greek word "amoibe," meaning "change" or "variation." It refers to a single-celled organism that can change its shape.
no a change in shape is physical change
Likely an amoeba, which is a type of unicellular organism that moves using pseudopodia, or temporary extensions of its cell membrane. Amoebas are known for their ability to change shape and move by extending and retracting their pseudopodia.
can solid change shape
An amoeba does not have a fixed shape. It is a single-celled organism that can change its shape constantly by extending and retracting its pseudopods, which are temporary extensions of its cell membrane used for movement and feeding.
