Answer:

The correct answer is option A, Cyanobacteria are photoautotrophs

Explanation:

Being photosynthetic and aquatic, Blue green algaes are considered to be the Cyanobacteria and they belong to the category of  aerobic photoautotrophs. The common essentials required for their survival are water, carbon dioxide, inorganic substances and light. Photosynthesis is their principal mode of energy metabolism. They are considered as an important contributor of oxygen in the Earth’s atmosphere.

erastovalidia [21]

Explanation:

Angiosperm are plants which is known for flowering plant on the earth. The flower is reproductive parts of the angiosperm plant. They are including 4 basic parts of the flower: Carpel, Stamens, Sepals and Petals.

During angiosperm plant reproduction, 2 structure are formed which are known as the Endosperm and a Zygote. Later a Zygote will grow and form a embryo and the endosperm is known for food source of plant embryo. Endosperm and Zygote forming process is known as double fertilization and it is a unique process found in angiosperms.

Steps involved in double fertilization are:

1) The pollen tube processing to release 2 sperm cells into an unfertilized ovule.

2) When one sperm cell fuses with the eggs to the formation of zygote and another sperm fuses with the 2 polar nuclei to the formation of endosperm this process is known as double fertilization.

3) After the completion of double fertilization, a fruit and seed develop.
