BIOL 140 Lecture Notes - Lecture 26: Nectar, Stamen, Ovule
Document Summary
Male side: filaments (white strips) and anther (package at the end full of pollen grains) Travel down to fertilize things in base of the flower. This is self-fertilization (both female and male parts) This leads to a lot of genetic issues. Mother realizes that she"s not storing enough energy she needs to mature all her kids - has to grow roots, branches, replace leaves. Not genetics, she doesn"t have the resource to develop what she thought. Green things at bottom and purple flowers are both petals. Evolutionarily they"re leaves but at the base they"ve been modified to protect the ovule and the colorful ones are advertisements. Pollen sacs are further out than the anthers. Moth comes in with pollen from another flower. Picks up pollen on outside and puts same pollen further on the inside. The nectar is different from the nectaries on the acacia trees. Different types of sugar: nectaries outside of flowers, nectar in the flower.
