Answer:
The correct answer would be "The female cone releases its seeds and new sporophytes grow".
Conifers are sporophytes with two types of cones; pollen cones and ovulate cone.
The pollen cones are smaller in size and produce microspores which would develop into the pollen grains.
The ovulate cones are larger in size which produce megaspores which would develop into ovule.
The two gametes fertilized to produce a diploid zygote which develops into the embryo.
The fertilization takes place in the ovule and thus, embryo or seed is developed in the female cone.
The female cone then releases its seed which grows into a new sporophyte.
Answer:
photosynthesis
Energy enters the ecosystem via sunlight as solar energy. Primary producers (a.k.a., the first trophic level) turn that solar energy into chemical energy via photosynthesis. Common examples are land plants, photosynthetic bacteria and algae
The following segment would be in the material and methods
section of laboratory report. The section materials and methods is used answer the
questions “what did you do?” and “how did you do it?” to describe what apparatus
and methods are used and to analyze the process. This segment states that author
tested efficiency of chelation in treating atherosclerosis and answers to the
first question. Answer to the second question is that he did it by examining the
effect of EDTA on egg shells.
