All of the F1 plants of Mendel's peas were tall because the tall trait was dominant over the short trait. Mendel crossed purebred tall peas (TT) with purebred short peas (tt), resulting in F1 offspring that all inherited one tall allele from each parent (Tt). Since the presence of just one dominant allele (T) is enough to express the tall phenotype, all F1 plants exhibited the tall trait.
All of Mendel's first-generation plants were tall because they were all homozygous dominant for the trait of tallness. This means they received two dominant alleles for tallness from the parental plants, resulting in expression of the tall phenotype.
f1 Generation
The Punnett square would show that all offspring would be heterozygous for the trait, meaning they would have one allele for tall plants and one allele for short plants. This would result in all offspring being tall plants phenotypically, but carrying the allele for short plants.
No, not all tall pea plants are purebred for tallness. In Mendel's experiments with pea plants, tallness is a dominant trait, but if a tall plant is heterozygous (having one allele for tallness and one for shortness), it can produce offspring that are either tall or short. Only plants that are homozygous for the tall trait (having two alleles for tallness) will consistently produce tall offspring. Thus, genetic testing or breeding records are needed to determine if a tall pea plant is purebred.
All the offspring were tall plants. This is because the tall trait is dominant over the short trait in Mendel's experiments on pea plants.

they were all hybrids
In the first generation of crossing tall peas with dwarf peas, all the offspring will be tall. This is because the tall trait is dominant over the dwarf trait. Each offspring will inherit one tall allele from the tall parent, resulting in all tall offspring.

chlorophyll makes peas green along with all the other plants
Mendel first described what is called genetics. He used sweet peas and crossed pure bred plants. For example, he crossed short pure bred (recessive) with tall pure bred plants (dominant). If tall is dominant, all plants would be tall. Crossing these hybrid plants would give a ratio of 3 tall to 1 short. This is the basis from which all studies of genes come from.
Peas like all plants need air.
