Answer: adjective. Botany (of an ovary) having two carpells.
Answer:
1) The general characteristics of kingdom plantae are as follows −. Multicellular organisms with walled and frequently vacuolated. Eukaryotic cells. Contain photosynthetic pigments which are present in plastids. They are autotrophic mode of nutrition. Plants are non-motile, live anchored to a substrate. Autotrophic
: All plants are autotrophic, making and producing their own food and nutrients, without needing others to provide it for them.
Multicellular
: All plants all multicellular, meaning they are composed of more than one cell, which is what makes them visible to our naked eyes.
Eukaryotic: All plants are eukaryotic, meaning their cells all contain a nucleus, which is one of the organelles of the cell surrounded in a cell membrane. four characteristics that distinguish land plants from charophyte algae.
2) Alternation of generations (w/ an associated trait of multicellular, dependent embryos), walled spores produced in sporangia, multicellular gametangia, and apical meristems. These are evolved traits of land plants. Not all plants have retained these traits.

I added explanations inside the answer. I hope it make sense.
Answer:
here are several methods of separating mixtures. The common ones are:
1. Winnowing
The wind is used to separate wharves (chaff), small sticks, and dry leaves, from grains or seeds by blowing the chaff away.
Chaff is usually lighter than the grains.2. Sieving
a sieve is used to separate mixtures of particles of different sizes. For example stones from flour.
The larger particles remain on the sieve while the finer ones pass through.
3. Picking
Here the large particles are separated from smaller ones by observing them and using the hands to remove the unwanted ones.
For example, stones are separated from rice or beans in this way.
4. Filtering
This method is used to separate a liquid from particles that cannot dissolve in it.
For example, separating sand from water using filter paper or piece of cloth.5. Decanting
This is when a liquid is separated from large particles of solids by pouring the liquid out gently.
For example, pouring off kerosene that has mixed with tiny ball bearings.
