travels down it and fertilizes the egg. The fertilized egg develops into the embrvonic sporophyte plant. The
embryonic plant is enclosed within a seed, which contains the embryo and food to support its metabolism
through germination and initial growth. The embryo and its food are protected by a seed coat. Another name
for the ovulate cone is seed cone. The slide in this set is a longitudinal section through a pine ovulate cone. Each
scale of the cone bears two ovules.

REVIEW QUESTIONS:
1.
How are the life cycles of mosses and ferns similar? How are they different?
2.
In some respects, mosses can be seen as not fully terrestrial. Explain.
3.
How are seeds different from other plant dispersal structures?
4.
ving evolutionarily through plant groups, from the nonvascular plants to the flowering plants, the
gametophyte generation becomes more reduced. Explain how this pattern coincides with early plants' move
from aquatic, or at least moist, to terrestrial habitats.

Step 1

Hi! Since you have posted many questions, we will be answering the first one for you. If you want the answers to the other questions, please post them separately.

Plants are eukaryotic organisms that are multicellular. They are autotrophs because they produce their own organic nutrition from inorganic molecules through photosynthesis. They have pigments which are green in color and are called chlorophyll that conducts the process of photosynthesis. Based on many characteristics, the entire Plant Kingdom is divided into Thallophyta (algae and fungi), Bryophyta (moss), Pteridophyta (ferns), Gymnosperms and Angiosperms.
