4-7 days You need about 120 days for most varieties of pumpkins. Giant pumpkins and other giant varieties require 130 to 150 days.
Seeds can be dispersed through wind (anemochory), water (hydrochory), animals (zoochory), and by explosive mechanisms (ballochory).
Some seeds are spead by animals, eating the fruit with the seeds then later the seeds come out the back end somewhere else. Other times, seeds are spread by the fruit just droping off the plant.
Gravity affects seed germination by altering the placement of plant hormones which affect the direction the first root grows and the direction the shoot grows. Gravity pulls some hormones downward which cause roots to grow down while the shortage of that hormone plus the presence of other hormones cause the shoot to grow upward. It doe not matter which way the seed is planted, this will not have an effect of the developing seedling.
The waxy cuticle prevents water loss by forming a watertight seal around the plantPollen and pollination allows the plants to transfer spermThey got a diploid genomeXylem and phloem help transport water and nutrientsRoots absorb waterLeaves provide a photosynthetic surfaceRoots, stems, and lignin provide mechanical supportSeeds, flowers, fruits, and cones allow for the dispersal of offspring
The four most common factors contributing to seed germination is water, oxygen, temperature and light/darkness.

There are lots of things underground: caves, worms, roots and seeds are four things.
It depends on the type of seed. Some seeds are more delicate then others. There are actually some types of seeds that require being damaged before they will germinate. Some require passing through the digestive system of certain animals, many prairie type plant seeds need to be burned first. There is a type of canna lily I have here at home that need to be scarified before they will germinate. I have to sit there with a nail file and file a section of the outer shell off before putting them in the ground. After that, they sprout in just a day or two. I have also started avocado trees from seed by shoving four tooth picks deep into the seed and putting the bottom half in a glass of water for a few weeks. They are a few feet high now. For the best results, you just have to read up on what you have.
P.E class.

four.
The number of seeds in the first four is 11 because each seed packet contains a different number of seeds, and when added together, they total 11.
Four.
From 1979 - 2010, 54 no 1 seeds have made the final four. That's 42.2%
Yes. There is four vegetables that has seeds in it. Tomato, Cucumber, Bell Peper, okra.
Need means require.
