How do cells move?
Cells can move through a process called cell migration, which involves coordinated changes in the cell's shape and movement of its internal components. This can be driven by signals from the environment, such as chemical gradients or physical cues. Cells can move using structures like cilia, flagella, or by extending protrusions like lamellipodia and filopodia.
What are specialized structures in a cell that perform specific functions?
Some specialized structures in a cell include mitochondria for energy production, ribosomes for protein synthesis, lysosomes for intracellular digestion, and the nucleus for housing genetic material. Each structure has a specific function that contributes to the overall functioning of the cell.
What is the principle of metachromatic granule staining?
metachromatic granules are polyphosphate granules found in Corynebacterium diphtheriae. They have the property of taking up a stain and exhibiting a different colour - metachromatia. thus they take up malachite green and appear dark blue in colour.
What types of cells divide the least often?
Answer: The internal lining of your digestive tract. Explanation: The internal lining of your digestive tract receives a lot of wear and tear. As a result, cells that line your stomach and intestine are replaced every few days. In contrast, cells that make up the rest of your intestine (mainly smooth muscle) and many of your internal organs, such as lungs, kidney, and liver, divide only occasionaly, in respons to injury or cell death.
What are somatic cell and germ cell?
Germ cells are cells that become gametes (are n: have have the genetic material) and somatic cells are all the rest (2n)
What is the internal transporting tissue in some plants that is made up of tube like structures?
The internal transporting tissue in plants made up of tube-like structures is called xylem. Xylem is responsible for transporting water and minerals from the roots up to the rest of the plant.

When was Ever Rest created?
Ever Rest was created in 1832.
Where did the rest of your cells come from?
from pre-existing cells.
Are you at rest?
Physically, no one is ever at rest.
What is the oplasm?
In cells, three different parts have "oplasm" in their name: rough endoplasmic reticulum, the smooth endoplasmic reticulum, or the cytoplasm. Assuming you meant cytoplasm, its the fluid that surrounds the rest of the structures inside the cell.
Which organ has cells with branch like structures?
Neurons in the brain and nervous system have branch-like structures called dendrites, which receive signals from other neurons. These dendrites help transmit electrical signals throughout the nervous system.
What system of cells tissues and organs regulates the body's responses?
The nervous system is responsible for regulating the body's responses. This system co-ordinates the brain with the rest of the body in order to control how your body reacts to external and internal stimulli.

Examples of stinging cells?
Jellyfish sting their prey using nematocysts, also called cnidocysts, stinging structures located in specialized cells called cnidocytes.
What is is the difference between prokaryotic and eukaryotic cells?
eukaryotic cells have a true nucleus and membrane-bound internal organelles. basically this means that eukaryotic cells organelles do not float around but have a specific spot in the cell. the organelles in a eukaryotic cell are each surrounded by a membrane isolating the organelle from the rest of the organelles. prokaryotic cells lack a true nucleus and do not have membrane-bound internal organelles. basically this means that prokaryotic cells have SOME organelles but the organelles that they do have float around. Most prokaryotes are single-celled organisms such as bacteria.
