Question

Plant growth is affected by environmental factors such as gravity. If a seed is allowed to sprout and grow while it is turned sideways, which will most likely occur?

Answer 1

The determining conditions of the medium are: Sufficient supply of water, oxygen, and appropriate temperature. Each species prefers to germinate a certain temperature; In general, extreme cold or heat conditions do not favor germination.
Temperature is a decisive factor in the germination process, since it influences the enzymes that regulate the speed of biochemical reactions that occur in the seed after rehydration. ... Therefore, the seeds only germinate within a certain temperature range.

Answer 2

If a seed is allowed to sprout and grow while it is turned sideways, roots will grow downward, stems will grow upward.

TROPISM:

• Tropism refers to the movement of an organism or part of an organism in response to stimuli. Tropism can either be negative or positive.

• Positive tropism refers to movement in the direction of the stimulus while negative tropism refers to movement away from the direction of the stimulus.

• In a plant, the stems are known to respond away from gravity i.e. they are negatively geotropic while the roots grow in the direction of gravity i.e. positively geotropic.

• Therefore, If a seed is allowed to sprout and grow while it is turned sideways, roots will grow downward, stems will grow upward.
