∙ 12y agobecause there aere lots of cells in ur body and u need to fit them all in :)

What are 2 characteristics of substances that do not allow them to pass through semipermeable membranes of living cells?
Substances that are large, charged, or polar
Explain why large active organisms need special surface for exchange?
large organisms need larger area to exchange more substances.but large organisms have small surface area to volume ratio.this means that the surface is not large enough to enable gases and nutrients at the fast rate needed to keep all the cells alive.thus large organisms need special exchange surfaces to provide the body with the nutrients and gaseous exchange they require.
Why must cells be small?
If the cell is large the substances can not get into and out of the cell fast enough to deliver the things the cell needs to live.
The size of cells is limited by their?
Cells are limited in size by the rate at which substances needed by the cell can enter the cell through its surface. volume increases faster than surface area and homeostasis is disrupted by a cell that is too large
What is the function of stomata and guard cells?
There are a large number of tiny pores called stomata on the surface of leaves of plants (The singular of stomata is stoma).Each stomatal pore (or stoma) is surrounded by a pair of guard cells .The opening & closing of stomatal pores are controlled by the guard cells.

Why can small cells exchange subtances more readily than large cells?
Small cells have higher surface area to volume ratio than larger cells.
How do large substances get into and out of cells?
Exocytosis takes substances out of the cell and endocytosis brings substances into the cell.
Which substances passes most readily into a cell ions large molecules glucose carbon dioxide or polar molecules?
Ions

What is Substances formed from plasma contains a large number of white blood cells?
Bone marrow
What do cells that secrete large amounts of substances via active transport need a large amount of in their cytoplasm?
Mitochondria for ATP(energy)
When do cells do active transport?
When transporting substances from low to high concentration, or when transporting substances too large to pass through the membrane without assistance from a transport protein.
Why must cells be small?
If the cell is large the substances can not get into and out of the cell fast enough to deliver the things the cell needs to live.
What features of the alveoli mean that gas exchange is more efficient?
They Have A large surface area and they are full of red blood cells
Why do large organisms require a circulatory systems?
Larger organisms develop cells that each do very specific chores. They depend on other cells to deliver the required oxygen and nutrients. The circulatory system allows the cells that are in charge of providing these required substances to the other cells.
