Why did only the #4 soil (people) produce fruit? Plants need adequate water and sunlight. But not to much water or the cells burst. Or too much sunlight and they scorch.
Seed germination starts when a seed is provided
with water. As seeds imbibe water, they expand and enzymes and food supplies become hydrated. Hydrated enzymes become active and the seed increase its metabolic activities to produce energy
for the growth process. In addition, the water causes turgor pressure to increase in the cells and they are able to enlarge. Or they can burst if they imbibe too much water.
The first part of the seedling to emerge from the seed coat is the root. The emergence of the root is typically used as the first indication that
a seed is viable.
Matthew 13:6 But when the sun rose it was scorched, and because it did not have enough root, it withered. ... Matthew 13:5 it did not have any depth of soil.
Eventually the shoot will also expand and emerge from the seed.
If germination occurs in darkness, root growth slows after the shoot emerges and shoot elongation accelerates. This behavior increases the chance that the seedling will emerge from soil into the light where it will be able to obtain energy from sunlight by photosynthesis.
Once a seedling emerges into the light, the plant undergoes dramatic changes such as turning green and producing leaves. This
light-dependent developmental transformation is called photomorphogenesis.
Luke 8:7 And other seed fell in the midst of the thorn plants, and the thorn plants grew up with it and choked it.
Luke 11:34 Your eye is the lamp of the body. When your eye is sincere, your whole body is full of light also. But when it is evil, your body is dark also.
In darkness, as would occur for seeds buried in soil, most of the food reserves in the seed are used to provide resources for the seedling to grow enough to reach the light and produce its own food by photosynthesis.
Through gravitropism, the seedlings can send their shoot towards the surface of the soil where it will eventually emerge into light. At the same time.the seedling uses gravity to orient its roots so
they grow down into the soil where they can find water and minerals for growth.
Luke 8:6 And other seed fell on the rock, and when it came up, it withered, because it did not have moisture.
John 4:10 Jesus answered and said to her, “If you had known the gift of God and who it is who says to you, ‘Give me water to drink,’ you would have asked him, and he would have given you living water.”
Luke 8:11, 15 Now the parable means this: ... bear fruit with patient endurance.
