How does material enter and leave a cell?
Materials can exit the cell using exocitosis. Endocitosis is when cells enter the cell by the cell forcing the material to enter. Osmosis and diffusion are also ways that materials can enter/exit the cell. Remember, the cell membrane is made up of protein channels and fat layers!
What is a cell structure that forms passage ways in which proteins and other materials threw the cell?
nucleus
How do you explain the entrance and exit of materials in a cell?
Materials can enter and exit cells in multiple ways. There is the process of osmosis, where water particles move through the partially permeable membrane in the cell wall to a higher concentration gradient - this does not require energy. There is also diffusion, where particles small enough to fit through the partially permeable membrane move down a concentration gradient - this also does not require energy. And then there is active transport, where the cell wall can actually move particles into the concentration gradient they would not naturally move to, and this does require energy. Hope I helped :)
Why might material need energy to move through the cell membrane?
The materials don't need energy its the cell that needs energy to pick up the material. The process in which a cell gathers materials while using its energy is call Active Transport. There are several ways in which the cell can pick up materials. It can wrap its membrane around it and form a vacuole or storage space for it. Or it can send some of its proteins to go and get it. There are also many more ways but those were just a few. To do these things cost the cell energy. There is a way although, for the cell to gather materials without using its energy. This is called Passive Transport. This can occur when there is a high concentration of water molecules outside of the cell, and a low concentration inside. The water naturally moves into the low concentrated area and it brings the dissolved materials with it.
What are three ways that planet cells is different from an animal cells?
Three ways that a plant cell is diferent from an animal cell are a plant cell has a cell wall and a chloroplast and they have a bigger vacoule.
3 ways materials enter and leave cell?
Materials can enter a cell through processes like diffusion, facilitated diffusion, and active transport. These substances can leave a cell through processes such as diffusion, osmosis, and exocytosis.
What are 2 ways a cell eats food?
Two ways a cell can eat food is by one, endocytosis which is when non-dissolved materials or food enter through the cell membrane to the cell's cytoplasm. These non-dissolved materials come from the outside environment. This way also includes phagocytosis in which an cell use pseudopods to help bring in the non-dissolved materials from the outside environment in to the cytoplasm. The second way is what a plant cell use get it's food is by chloroplast ( part of a cell ) which makes food from carbon dioxide, sunlight, and water.

What are four ways materials can be consider public domain?
Materials can enter the public domain when copyright term expires, protection is not renewed (renewals are not available for new works), the creator donates the work to the public domain, or the materials are a work of the US Government.
Identify at least five ways by which a substance may enter the cell?
A substance can enter a cell through diffusion, facilitated diffusion, active transport, endocytosis, or passive transport. Each of these processes has different mechanisms for moving substances across the cell membrane.
What is a cell structure that forms passage ways in which proteins and other materials threw the cell?
nucleus
Name the 2 ways that materials can pass through the cell membrane?
The two ways that materials can pass through the cell membrane are active transport and passive transport. In active transport the molecules cannot pass freely across the membrane and have to be carried across in ways that require energy. In passive transport the molecules can pass freely across the membrane in ways that do not take any energy.
What type are osmosis and diffusion?
diffusion and osmosis are types of ways to get materials into or out of a cell
There are 2 entries to a hall. In how many ways you can enter and exit from the hall?
It depends if their is a window in the hall, because you can exit or enter the hall through a window, and you can only enter two ways, and exit two ways, making for a combined total of four ways to enter and exit the hall. its either that or there is 2 enterances and no exits
What are four ways a controlled product can enter the body?
absorption, injection, ingestion and breathing
What are four ways poison can enter your system?
ingestion, inhalation, cuts, and through holes
What four ways can enter the body and what should you do if someone is poisoned and why?
The four ways that poisons can enter the body are by absorption, inhalation, injection(bleed), and ingestion. If someone is poisoned, then I guess you should call 911 for an ambulance because you are dying from poison and you don't know how to cure it.
