Plants are decisive to a fault. A stem produces a bud that flowers once and once only. It offers pollen that is either dispersed or goes nowhere. One pollen grain either enters a stigma or it falls upon stony ground. An ovum is either fertilized or the whole project stalls out.

Conjoined twins are identical siblings who develop one placenta out of a single fertilised ovum. No cases of conjoined triplets or quadruplets have been documented.

Used in biology, often in discussions about reproduction and fertilization processes.

Biological Context

Referring to female humans, 'ovum' emphasizes the scientific aspect of the egg cell.

Human Focus

'Ovum' is often used in contexts about the egg pre-fertilization or during fertilization.

Fertilization Specific

In botany, 'ovum' refers to the part of the plant involved in sexual reproduction.

Plant Biology Use

'Ovum' is not as familiar in everyday language but is specific to plant biology.

Botanical Reproduction

Understanding 'ovum' in plants includes knowing its role in seeds and spores.

Spore and Seed

 What if you could change the sperm and the ova, or change the newly fertilized egg, and give your offspring a better chance at a healthier life -- eliminate the diabetes, eliminate the hemophilia, reduce the risk of cancer?
