Four viable sperm cells are produced from one primary sex cell, whereby only one viable egg cell is produced, due to the unequal division of cytoplasm and the formation of polar bodies, which wither and die.
Very thin foil. It can be large in 2D as pool foil, or rolled-up to 3D space like in the AA cell or electrolytic capacitor. A pasta shapes are also good example, how to have minimal volume and maximal surface to get it boiled quickly.
One difference between cell division in plant cells and in animal cells is that plant cells have a cell plate. Animals cell's have a cleavage furrow.
Cell is the structural and functional unit of life while ,unicellular organism refers to an organism. Cell is present in both unicellular and multicellular organisms where as , unicellular organisms are composed of only one cell.
No.
yes
one to one
A 'ratio' shows a relationship between two numbers. There's no such thing as the ratio of one single number.
1,000,000,000,000,000,000:1
A rational number is one which can be expressed as a ratio of two integers.
yes, if the golden ratio is ((square root 5) +1)/2, then the silver ratio is (square root 2) +1. as the golden ratio is represented by phi, the silver ratio is represented by deltas. as two quantities are in the golden ratio if the ratio of the sum of the quantities to the larger quantity is equal to the ratio of the larger quantity to the smaller one, two quantities are in the silver ratio if the ratio between the sum of the smaller plus twice the larger of those quantities and the larger one is the same as the ratio between the larger one and the smaller.
high SA:V ratio, so no transport systems needed
You are probably thinking of the surface area to volume ratio. When you have two small cells instead of one big one, there is more 'outside'.
As a cell becomes larger the surface area to volume ratio gets smaller. The volume increases by the square of the surface area. That is the main reason that one celled organisms are small.
Yes.
They areseparatedby a cell wall or a cell membrane.
