What else can I help you with?
What are the materials surrounding the nucleus?
some of the materials that surround the nucleus is the cytoplasm, mitochondria, lysosomes, Golgi body and apparatus.
Where are materials exchanged from the cells to the blood?
Materials are exchanged between cells and the blood mainly at the capillaries. Capillaries are tiny blood vessels with thin walls that allow for the exchange of gases, nutrients, and waste products between the blood and surrounding tissues. This exchange process occurs through the process of diffusion.
How is your blood able to bring some materials to your cells and remove other materials?
The blood achieves this through a process called circulation. It carries oxygen, nutrients, hormones, and immune cells to the cells, allowing them to function properly. At the same time, waste products like carbon dioxide and metabolic byproducts are transported away from the cells to be eliminated through organs such as the lungs and kidneys. This process is facilitated by the network of blood vessels, including arteries and veins, that connect all the cells in the body.
Do some white blood cells surround ans swallow whole germs?
Some do and these are called macrophages. The word macrophage means big eater.
What is a endocytosis general description?
There are two types of endocytosis: Phagocytosis (cell-eating) and Pinocytosis (cell-drinking). Endocytosis is a process in which a cell fully engulfs materials from the outside and fuses them to its plasma membrane. These materials are usually the larger of materials since they aren't small enough to cross the cell's plasma membrane by some sort of diffusion. Endocytosis is an energy using process in which cells absorb molecules by engulfing them.
What two substances control the movement of materials into and out of the cells?
Some of the proteins and lipids do control movement of materials into and out of the cell.
Why do you need to process some materials before you can use them?
We process materials to make them better and more useful. We are therefore we are modifying the natural material to advance it.
What are ways in which materials may move in and out of cells?
Some ways in which material may move in and out of cells are diffusion and also osmosis.
What bulk transport moves materials out of cells?
exocytosis
What is the process in which some unicellular organisms split into 2 cells?
Mitosis
What process do some cells go through to become specialized?
differentiation
What process takes place only in plant cells?
A process that is found only in plants and some bacteria is?
