What transport process does oxygen move across the cell membranes and into your red blood cells?
diffusion
Most of the food and waste materials that move into and out of a cell pass through?
Receptor Proteins
How do the small molecules of oxygen and carbon dioxide move through the cell membrane?
They move via diffusion across a gradient.
How does cilia help the sponge larvae?
It helps them move.
Oxygen molecules move into a cell and carbon dioxide molecules leave because of differences in concentrations considered filtration?
Yes
What is the name of the hair-like structures on a sponge cell that moves back and forth to help move water or nutrients or waste through the canal?
The hair like structures on sponge cells can be either cilia or flagella. These structures project from the surface of the cell and help to move substances.
How do sponges breathe?
A sponge gets its oxygen from the water. The oxygen moves from the water to the sponge by a process called diffusion. Diffusion is when molecules of a substance move from an area where they are highly concentrated (where there are a lot of oxygen molecules) to an area where they are less concentrated (where there are not a lot of oxygen molecules). Oxygen is more highly concentrated in the water then in the sponge. Therefore, the oxygen goes from the water to the sponge.
What is the respiration of a sponge?
A sponge takes in water through its pores and in more advanced forms, with canals that move the water to all throughout the sponge. Then the oxygen from the water is used.
What are the main functional of a cell?
1. Take in food and oxygen 2. Produce heat and energy 3. Move and adapt to their environment 4. Eliminates waste
What are the four functions of a cell?
1. Take in food and oxygen 2. Produce heat and energy 3. Move and adapt to their environment 4. Eliminates waste
What 2 materials move across the cell membrane?
waste and nutrients
Why is it helpful for cells to divide?
The larger a cell becomes, the more demands it places on its DNA . It also becomes more difficult for the cell to move nutrients and oxygen in, and waste products out. The ratio of surface area to volume becomes too small.
What structures supplies food and oxygen to the sponge?
The pores of the sponges are responsible for the supply of food and oxygen. As they are SESSILE (fixed at one place) so they can't move to catch their prey, but their pores do the work for them......
What is a cell wall for?
It keeps the cell "guts" in and other stuff out. The cell wall also acts as a transport system to move nutrients and needed molecules in and waste products out of the cell.
What compared to small cells large cells have more trouble?
Because if they did not separate nutrients and waste could not move acroos the cell membrane quickly enough to send it throughout the entire cell. This would cause the cells to die. That is why they divide instead of growing larger.
What cell move around in the mesohyl delivering food and oxygen to other cells?
amebocytes
How do yellow sponge tubes move?
when they are young they move to attach to another sponge but when they attached and are full grown they don't
