Lettuce and spinach has a semi permeable membrane
since it's put into water, which water has a higher water potential than the leaf cells, water molecules will pass from the water to the cells through the membrane by osmosis . this leads the cells to be turgid and therefore the lettuce and spinach becomes firm

A genotype is controlled by the sex cells combining to form an organism. True or False
myrzilka [38]

True

A genotype is the combination of genes in its DNA of the organism that determines its traits

Explanation:

Gametes from parents contribute different alleles of genes to their offspring. This why gametes carry only one copy of genetic material of the organism. They later fuse to form a zygote with a full genetic copy and capable of developing into an full organism.

Depending on which kind of alleles the parents pass down to the offspring will determine the offspring's genotype. The genotype of the offspring will, on the other hand, affect its phenotype which is the outward characteristic. An example is the sickle cell trait. If both gametes from the parents contribute the recessive alleles of the gene, then the offspring will be homozygous recessive for sickle cell genotype and this will show in the phenotype pf the person who will have sickle cell shaped blood cells.
