Cell walls are made of cellulose in ____________ cells.
pickupchik [31]
I believe the answer would be D, plant. Plant cell walls appear as tiny little boxes that are given their shape by two chemicals: cellulose and lignin. Cellulose is the basic structural component of plant cell walls and is also found in vegetable matter, cotton and wood. High amounts of cellulose are consumed by herbivores, usually with the assistance of bacteria.

In garden pea plants, purple flowers (P) are dominant to white flowers (p), and full pod shape (F) is dominant to constricted po
kifflom [539]

Answer:

The phenotypes are as follows

Purple, full- 9

Purple, constricted- 3

White, full- 3

White, constricted- 1

Genotype of parents are PpFf, each produce the following gametes: PF, Pf, pF and pf.

Explanation:

This is a dihybrid cross involving two distinct genes. One coding for flower color and the other for pod shape. The allele for purple color (P) is dominant over the allele for white color (p) while the allele for full pod (F) is dominant over the allele for constricted pod (f).

In a cross between two heterozygote parents i.e. PpFf × PpFf, each parent will produce the following gametes: PF, Pf, pF and pf. Using these gametes in a punnet square (see attached image) the following 16 offsprings will be produced in a phenotypic ratio: 9:3:3:1

Purple color, full pod- 9

Purple color, constricted pod- 3

White flower, full pod- 3

White flower, constricted pod- 1
