A structure that is found in a plant cell and not in an animal cell is a central vacuole.
Option A
<u>Explanation</u>:
Plant cells are different from animal cells because a large central vacuole is present in the plant cell which is filled with water and salts to create a turgor pressure which gives the cell the physical strength to overcome the water pressure. The central vacuoles are not present in the animal cells but there are small vesicles which transports the molecules from surface to cytoplasm or vice versa.
It is called IMPLANTATION. the zygote is embedded into the uterus lining. Starting from there, the zygote will soon develop into a embryo and soon a fetus under amniotic fluid and an umbilical cord to transfer food and waste in and out.
