Hello, so i attempted to clone a cabbage by cutting the stem into 3 pieces, planting them in separate pots, and letting them grow. as a result the top part of the stem grew the most (had lots of leaves and long roots). the middle part had some leaves but not that as many as the top stem part. the bottom part didn’t have any leaves but had some roots.

i was wondering if someone could explain these results. do they have something to do with the xylem or phloem? or the meristems? or even the photosynthetic processe of the plant (more leaves=more photosynthesis)?

you

It is due to more meristems present there.

Explanation:

Meristem tissue can be described as the undifferentiated cells of the plant which have the capacity for cell division and convert into different parts of the plant.

The growth is the most at the apical meristems. At the shoot tips, there will be more meristems as compared to the other parts of the plant. This is the reason that the top part of the stem will grow the most.

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).

what do the different brain waves do?

explanation:

brainwaves are produced by synchronised electrical pulses from masses of neurons communicating with each other. brainwaves are detected using sensors placed on the scalp. brainwave speed is measured in hertz (cycles per second) and they are divided into bands delineating slow, moderate, and fast waves.
