What three types of cells must be present for flatworms to be able to respond to stimuli and move about?
Flatworms require muscle cells for movement, nerve cells for detecting stimuli, and epithelial cells for sensory integration and coordination of responses. These three cell types work together to allow flatworms to respond to their environment and move about.
Why can't viruses respond to stimuli?
They have no cells. So they do not respond
Muscle cells gland cells and specialized cells that respond to neural stimuli are called?
Muscle cells are called myocytes, gland cells are called secretory cells, and specialized cells that respond to neural stimuli are called neurons.
Why is sun not living?
The sun is not made of cells, does not respond to stimuli, and cannot reproduce.
What cells have the ability to respond to stimuli by generating signals such as action potentials?
Nerve cells or neurons have the ability to respond to stimuli by generating signals such as action potentials. These signals travel along the nerve cells to communicate information within the nervous system.
Many flatworms can detect changes in the amount of light in their environment using groups of cells called?
Many flatworms can detect changes in the amount of light in their environment using groups of cells called photoreceptors. These cells are sensitive to light and help the flatworms navigate and respond to their surroundings based on light levels.
A major characteristic of living cells is that they respond to various?
A major characteristic of living cells is that they respond to various stimuli in their environment, such as changes in temperature, pH, or nutrient availability. This ability to detect and react to external signals is essential for cells to maintain homeostasis and adapt to changing conditions.
How are flowers alive?
They are made of cells, have a metabolism, respond to stimuli, grow, reproduce, and are influenced by their environment.
What elements do living things have that volcanic rocks do not have?
Living things have cells, genetic material (DNA or RNA), the ability to reproduce, and the capacity to grow and respond to stimuli, none of which are present in volcanic rocks.
What do the receptor cells do?
Receptor cells are specialized cells that detect specific stimuli, such as light, sound, touch, taste, and smell. They convert these stimuli into electrical signals that can be interpreted by the brain, allowing us to perceive our environment and respond to it accordingly.
Some flatworms have clusters of nerve cells that control the nervous system each cluster is called?
Some flatworms have clusters of nerve cells called ganglia that control their nervous system. Ganglia are distributed throughout the body and help coordinate the flatworm's movements and responses to stimuli.
What are the characteristics of all living things?
All living things are made up of cells, require energy for growth and development, respond to their environment, reproduce to create new generations, and have the ability to adapt to changes over time.
