Homework Answers
1.- Parthenocarpy: Fruits that develop without fertilization of the ovules
Hypodermis: Layers of thickened cells in a pine needle
Softwood: Fruits that develop without fertilization of the ovules
2.- The answer is the fourth option: Cells of an embryo. All the other tissues aer haploid, except for the endosperm which is triploid
3.- All of them apply to both groups except Archegonium, the answers then are: Embryo, Pollen grain, Integument, Ovule
4.- Remember that the flowering plants are the most diverse currently, and their Phylum is Magnolyophyta, the fourth option.
5.- Archegoniums are the female sex structures for only plants without flowers (mosses, ferns and angiospermae). Then the answer is the last option: Magnolia ovule

1. In this question, assume that the life cycle of a flowering plant begins with the germination of a seed and ends with the development of a fruit. Two events that occur in the life cycle are formation of a pollen tube and pollination. What would be the sequence in which they occur? Group of answer choices Both events occur more or less simultaneously. Formation of a pollen tube precedes pollination. pollination precedes the formation of a pollen tube 2....
