Core Skill: Connections Look back to Figure 32.14 to see a more detailed illustration of the flowering plant life cycle. How can you recognize and where can you find the gametophyte generation of a flowering plant?
Figure 32.14 The life cycle of a flowering plant, illustrated by the genus Polygonum. Flowering plant life cycles differ in length and in the number of cells and nuclei occurring in the female gametophyte, with the seven cells and eight nuclei of Polygonum being common.

Lab 13 (a)- Vascular Plant Reproduction
Can you recognize if a cone is male or female?
If provided actual flowers or images of flowers, can you determine if they are from a monocot or
dicot plant (based on the expected patterns of petals)
Can you identify key parts of a flower (sepals, petals, stamen, pistil, anther, filament, stigma,
style, ovary, ovules)
Difference between perfect & imperfect flowers?
If a plant produces flowers, is it a gymnosperm or angiosperm?
What are the names and functions of the 2 cells within a pollen grain?
During double fertilization, what 2 structures are fertilized? What does each fertilized structure
become?
what are the flaws ?
Plants reproduce in a pattern known as alternation of generations. A haploid gametophyte produces gametes through mitosis. The gametes fuse to form a zygote, which then grows into a diploid sporophyte. The sporophyte produces spores through meiosis, which then grow into a gametophyte and start the process over.
Flowers are how angiosperms reproduce. A whorl of sepals (corolla) is at the base of the flower, followed by a whorl of petals (calyx). Inside the flower is a female organ known as a carpel and it is made of a stigma, style, and ovary. The male organ is the stamen and it is made of an anther and filament.
Pollen being transferred to the style is known as pollination. Once the pollen travels down the style and reaches the egg, fertilization happens when sperm meets egg. Then, the fertilized egg and surrounding tissue develops into a seed. A seed is protected by a seed coat and contains endosperm and an embryo. The endosperm grows into a new plant while…
Directions: Plants have two life stages. The gametophyte life cycle, wherein a
haploid spore is produced, and the sporophyte life cycle wherein there is union of the
gametes. Below are different events in the development of flowering plants. Arrange
them in the correct order. Place the number from 1 to 6 inside the box.
The hypocotyl pushes to the soil along with the cotyledon(s).
It starts as a seed which contain the miniature plant called embryo.
Of the two sperm cells, one sperm fertilizes the egg cell, forming a diploid
zygote; the other sperm fuses with the two polar nuclei, forming a triploid cell
that develops into the endosperm
Mature plant develops the gametes, releases the pollen and pollinates the
flower.
It is the process wherein seeds are transported, spread or moved away from
the parent plant either by wind, water, animals or insect.
The plant, given enough nutrients will develop in a mature stage.

Each unit of stem that consists of a leaf, axillary bud and internode is referred to as a phytomere. Note that axillary buds always occur above a leaf. Axillary buds give rise to branch shoots.

- READ THE FOLLOWING INSTRUCTIONS: Bryophytes in which the gametophytes are "leafy" in appearance and the sporophytes grow conspicuously from the tips of the gametophyte plants. STEP 1: Examine the mass of moss plants and then select one or two individual gametophyte plants and note the leaf-like (not true leaves because they lack conducting tissue) structures which are arranged around a central, vertical "stem-like" stalk and root-like rhizoids which anchor the plant and absorb water and nutrients. STEP: The sex organs are in the tips of the plants and must be seen with the microscope. Study a slide of a vertical section through head of a mate plant and note the many antheridia. STEP 3: Examine a slide through a vertical section of a female plant.
