100 Plants supply oxygen and are the ultimate source of most food eaten by land animals What are the main functions/contributions of plants to life on Earth?	100 Male Gametophytes Microsporangia produce:	100 Sporangia The organs in which sporophytes produce spores	100 Female Gametophytes Megasporangia produce:	100 seeds mature in enclosed chambers called ovaries; ex. All flowering plants Angiosperm
200 charophytes – The closest relatives of land plants Land plants evolved from green algae. Researchers have identified green algae as?	200 Homosporous Heterosporous • The ancestors of seed plants were likely: – ________________, • While seed plants are: – ________________	200 False • Land plants are not descended from modern/living charophytes, but • Share a common ancestor with modern charophytes True or False? Land plants descended from modern/living charophytes.	200 – The transfer of pollen to the part of a seed plant containing the ovules Pollination is:	200 Diploid cells undergo meiosis to generate haploid spores Sporocytes: Haploid or Diploid? Mitosis or Meiosis? What do they generate?
300 Charophytes Comparisons of both nuclear and chloroplast genes point to: _____________ as the closest living relatives of land plants	300 – Eliminates the need for a film of water – Great dispersion distances by air or animals Pollen advantages:	300 • Microtubules connecting the two daughter nuclei of a dividing cell • A cell plate develops in the middle of the phragmoplast across the midline of the dividing cell • A cell plate then gives rise to new cross wall (new cell wall) that separates the daug Define Phragmoplast:	300 A seed develops from the whole ovule The relationship between the whole ovule and the development of the seed in seed plants	300 Female gametangia Produce eggs and are the site of fertilization Archegonia
400 a. Scarcity of water b. Lack of structural support (e.g gravity) The type of challenges land presented to terrestrial movement of species	400 a. An embryo, and b. Nutrients, surrounded by c. A protective coat The different component of a seed	400 a. Unfiltered sun b. More plentiful CO2 c. Nutrient-rich soil d. Few herbivores or pathogens The advantages/benefits that terrestrial environment provided to earlier species of plants upon their movement to land	400 A pollen tube - that discharges sperm into the female gametophyte within the ovule What does pollen grain germination gives rise to?	400 • Land Plants • Dependency of the embryo on the parent Embryophyte:
500 a. Rose-shaped complexes for cellulose synthesis b. Peroxisome enzymes c. Structure of flagellated sperm d. Formation of a phragmoplast The four characteristics that the closest relative of plants share with plants?	500 a. Megasporangium b. Megaspore, c. One or more protective integuments The components of the ovule in seed plants	500 a. Alternation of generations b. Walled spores produced in sporangia c. Multicellular gametangia d. Apical meristems The key traits that are only found in land plants but are absent in charophytes (green algae)	500 a. They may remain dormant for days to years, until conditions are favorable for germination b. They may be transported long distances by wind or animals The evolutionary advantage(s) of seeds vs. spores in terms of transport over a distance by winds and animals	500 A durable polymer layer in charophytes protecting exposed zygotes from drying out Sporopollenin:
