Gametes are cells used to sexual reproduction. they are haploids and that means they have just one set of chromosomes (most of the cells of our body have 2 sets). that kind of cells is produced mainly by meiotic division of the gamete's stem cell (called oogonium or spermatogonium) and that's why meiosis usually leads to the production of gametes. gametes are haploids so that they could combine (egg with sperm cell) and create the whole new organism (adult organism is almost always diploid).
Add a metabolic poison to the water to block any active metabolism and see if the seed germinates the same as without the poison.
- The percent increase in mass decreases with rising temperature. As temperature rises, its value approaches that of the percent increase in mass.
- There are two types of requirements for microbial growth: physical and chemical. Osmotic pressure, pH, and temperature are examples of physical factors.
- Water, supplies of carbon and nitrogen, minerals, oxygen, and organic growth stimulants are all chemical necessities.
- hence by using poison to block the active metabolism of seed the chemical growth will be restricted. If the seed still swells this means that it is a physical process.
- If the seed swelling stops then the process is considered chemical.

Well those that are in that ecostems could died from no water or the could walk on it and it breaks
Yes, more than one dichotomous key be developed to identify the same group of organisms.
The reason that more than one dichotomous key for the identification of the same group of organisms is possible is that the organisms are identified by a number of different characteristics and one person developing a key might use a different set of characters from another person.
