3. Starts forming flower

4. Starts forming fruits

Q. Vivipary is characteristic of

1. Mesophytes
2. Xerophytes
3. Hygrophytes
4. Halophytes

Q. What does this statement mean,
In higher plants, seeds and some other vegetative reproductive structures serve to *tide* over periods of stress. What does tide signify here?

Q. Mangrove plants show vivipary. This is
