A student conducted an investigation to study gravitropism. The control group was planted normally, while the experimental group was

planted upside down. After seven days, the control group looked

normal. The experimental group after 7 days the roots started to grow

toward the direction of gravity.

gametes or germ cells are haploid cells (example: sperm and ova) containing only one set (or n) number of chromosomes and autosomal or somatic cells are diploid cells containing 2n number of chromosomes.

those characteristics are cellular organization, reproduction, metabolism, homeostasis, heredity, response to stimuli, growth and development, and adaptation through evolution. some things, such as a virus, demonstrate only a few of these characteristics and are, therefore, not alive

garbage disposal because lysosomes dispose of old cell parts like garbage disposals dispose of old food.
