Chapter 35, Problem 18TYK
Summary Introduction
Introduction: Cell division and cell expansion are important events of plant growth. The processes of growth and differentiation are involved in the development of the plant. An increase in the size of the plant is referred to as growth. The process in which the cells become specialized to carry out different functions is known as differentiation.

Mitotic Cell division occurs in dogs, potato, zebra, and parrots cells. Which character will be absent in potato plants but present in dogs, zebra, and parrots cells?
a.
Root apical meristems are present where mitosis occurs.

The resulting cells will contain exact numbers of chromosomes comparing parental cells.

Star shaped Aster formation occurs around centrioles.
d.

Monoecious plants such as corn have either staminate or carpelate flowers. Knowing what you do about the molecular mechanisms of floral development, which of the following might explain the development of single-sex flowers?
a. Expression of B-type genes in the presumptive carpel whorl will generate staminate flowers.
b. Loss of A-type genes in the presumptive petal whorl will allow C-type and B-type genes to produce stamens instead of petals in that whorl.
c. Restricting B-type gene expression to the presumptive petal whorl will generate carpelate flowers.
d. All of the choices are correct.

And how could a forest fire be beneficial to a seed.arrow_forwardThe drooping, bell-like flower Aquilegia canadensis is adapted for cross-pollination. However, if the plant has not been pollinated previously, self-pollination can occur. However, if cross pollination occurs after self-pollination takes place, the pollen from cross pollination reaches the style before the pollen from self-pollination.
