Answer:
These are the factors that restrict the size of a cell:
-Surface area to volume ratio
-Nucleo-cytoplasmic ratio
-The fragility of the cell membrane
-Structures of the cell
The reason that the cell can grow to a certain limit is its surface area to volume ratio. For example as you air a balloon it expands to a certain volume but there is a limit you can fill air inside the balloon otherwise it will blast.

Answer:
If the chimpanzee’s zygote has 48 chromosomes, one would expect to find 24 chromosomes in a chimpanzee’s egg.
Explanation:
In a living organism, somatic cells are diploid and possess the full chromosome load, while gametes -sex cells- possess half of the total chromosomes, they are haploid.
The zygote of any organism that reproduces sexually results from the union of a male gamete and a female gamete, so its chromosome load is complete.
<em>This means that if the chimpanzee has 48 chromosomes in its cells, the female sex cell - the egg - has 24 chromosomes.</em>

Solution:
Cell-division control affects many aspects of development. Caenorhabditis elegans cell-cycle genes have been identified over the past decade, including at least two distinct Cyclin-Dependent Kinases (CDKs), their cyclin partners, positive and negative regulators, and downstream targets. The balance between CDK activation and inactivation determines whether cells proceed through G1 into S phase, and from G2 to M, through regulatory mechanisms that are conserved in more complex eukaryotes.
This is the required process through phosphorylation, Cdks signal the cell that it is ready to pass into the next stage of the cell cycle. As their name suggests, Cyclin-Dependent Protein Kinases are dependent on cyclins, another class of regulatory proteins. Cyclins bind to Cdks, activating the Cdks to phosphorylate other molecules.
Imbibition occurs when the seed is exposed to water. The seed absorbs water though its seed coat. As this happens, the seed coat softens.
