Answer:
1. Binary fission
Amoeba reproduces by the common asexual reproduction method called binary fission. After replicating its genetic material through mitotic division, the cell divides into two equal-sized daughter cells.
2. Sporangia
Leaves may be small or large. Vascular tissues are present in all the vegetative parts of the plant body. Reproduction involves the production of spores inside special structures called sporangia that can be found on the ventral surface of fertile leaves called sporophylls.
6. Each embryo starts development as a zygote, a single cell resulting from the fusion of gametes (i.e. fertilization of a female egg cell by a male sperm cell). ... A newly developing human is typically referred to as an embryo until the ninth week after conception when it is then referred to as a fetus.
7. Pollen grains represent the male portion of the reproductive process in plants and trees. These tiny bodies are swirling in the air and on the legs of insects so that they can join the female part of the plant to create a new seed. This important process is known as fertilization
