Question
Chapter 11.1, Problem 3CC
Summary Introduction
To explain:
Whether self-pollination is considered asexual or sexual reproduction
Introduction:
Reproduction is the process of producing the young ones from the existing one; it enables a species to survive within an environment. There are mainly two modes through which an organism can reproduce; sexual and asexual mode.

The 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. Using course concepts and vocabulary 1) Provide a reasoning for this phenomenon. 2) Would this adaptation for reproduction be beneficial for the plant?
MAKE CONNECTIONS In seed plants, how might retaining the gametophyte within the sporophyteaffect embryo fitness? (See Concepts 17.5, 23.1, and 23.4 to review mutagens, mutations, and fitness.)
Consider the following statements and indicate whether each presents an idea of Jean-
Baptiste Lamarck, of Charles Darwin or of both scientists. On the blank before the statement,
write L for Lamarck, D for Darwin or B for both.
1) An organism directs its own adaptations because of an inborn urge to be perfect (that
is, to be better suited to the environment).
2) Individuals do not evolve, but populations do.
3) Individuals in a population exhibit variation in their traits, such that no two
individuals are exactly alike.

4) Many different kinds of living things are adapted to their environment.
5) Members of a population who are better adapted to the environment have higher
chances of survival and reproduction.
6) Parents pass on their traits to their offspring.
