What else can I help you with?
What is phagocytosis and how does it work?
large particles or cells are engulfed by the cell plasma membrane
Is an Elephant large because it has large cells?
No, an elephant is not large because it has large cells.
Which have a better chance to be fertilized- the egg cells of fish of the egg cells of frogs?
The egg cells of fish have a better chance of being fertilized compared to the egg cells of frogs. This is because fish release a large number of eggs into the water, increasing the likelihood of encountering sperm for fertilization, while frogs typically lay fewer eggs and do not release them directly into the water.
Does Animal and plant cells have Large Vacuoles?
no they do not
What is small in animal cells but large in plant cells?
Vacuoles are small in animal cells but large in plant cells. They play a role in maintaining turgor pressure in plant cells and storing water, ions, and nutrients. In animal cells, vacuoles are smaller and more specialized in function.
Why are there small cells?
because if a cell is too large, it takes more DNA, work, and maintenance to keep it living, whereas if it is a small cell, transport is quicker and DNA, work, and maintenance are quicker and takes less effort than large cells* it is also better for cells to have a larger surface area: volume ratio so that transport is easier
What is phagocytosis and how does it work?
large particles or cells are engulfed by the cell plasma membrane
Why are small cells better then large cells for moving materials through membranes?
small cells have a greater surface-to-volume ratio than larger cells.
Why is a specialized group of small cells better than one large cells with the same volume?
It has more cell structures
What is a large group of similar specialized cells?
A large group of similar specialized cells is called a tissue. Tissues work together to perform specific functions in the body.
Why is a specialized group of small cells better than one large cell with the same volume one large?
It has more cell structures
Where does a muscle receive the energy from to contact?
What we call a muscle is really a large number of cells that work by contracting. Work that all cells do uses glucose, a simple sugar. This is used in producing ATP the "battery" that generates energy for the cells,
Why is a specialized group of small cells better than a large cell with the same volume?
It has more cell structures
Is an Elephant large because it has large cells?
No, an elephant is not large because it has large cells.
Why is it important that the large bones work with the circulatorty to produce blood cells?
so it can fight off bacteria
Why is a specialized group of small cells better than one large cell with same volume?
It has more cell structures
Why are groups at small cells better than one large cell at moving material in and out?
They have a greater surface-to-volume ratio
