Explanation:
CORRECT
Answer:
b) The roots grow towards the force of gravity and the stem goes away
Explanation:
The parts of a plant can be divided into shoot and roots. The root of the plant is the part that grows below the ground surface in order to anchor the plant. When a seed germinates, the root part of that seed grows towards GRAVITY i.e exhibits geotropism while the shoot part grows away from gravity i.e. upwards.
Hence, if a seed is planted upside down, it will still grow into an erect mature plant because THE ROOT WILL ALWAYS GROW DOWNWARDS IN RESPONSE TO GRAVITY (positive geotropism) while the stem grows upward away from gravity (negative geotropism)
The answer would be pituitary gland.
Completed sentence: Growth hormone is secreted by the pituitary gland while we sleep.
I’d imagine “located near a star” considering that stars are suns and planets orbit around suns. Like earth orbits our sun. So I would look at the star it orbits to determine that it is not in our galaxy.
