Plant Biology and Classification

In mosses, when antheridia and archegonia are on different branches of the same plant, the condition is monoecious (since both sexes are on one plant) and specifically paroicous (if they are on the same branch) or autoecious (if on different branches). Given the options, 'monoecious and paroicous' is the standard classification for this specific arrangement.

In bryophytes and pteridophytes and gymnosperms the male and female gametophytes to not have an independent free-living existence. They remain within the sporophyte. The gametophytes are quite large in Bryophytes as compared to other phyla like pteridophytes or angiosperms.

The family Crassulaceae is famous for containing species that exhibit CAM photosynthesis, but C3 and C4 species are also found within this diverse family.

Herbs are small, non-woody plants that typically live for one or two growing seasons before completing their life cycle.

1. Nudiflora is a fungus of genus Cercospora.
2. Glumaceae is a term used by Bentham and Hooker that include grasses.
   
3. Epigyne is an order of plant which has an epigynous ovary.
4. Microspermae is an order of flowering plant refers to the size of a seed.

• Poaceae or Gramineae is a large and nearly ubiquitous family of monocotyledonous flowering plants known as grasses. Poaceae includes the cereal grasses such as paddy, wheat, rice; bamboos and the grasses of natural grassland and cultivated lawns and pasture.
• The mustard plant is a plant species in the genera Brassica and Sinapis belonging to the family Brassicaceae.
  
• So, the correct answer is 'Mustard'

Poaceae or Gramineae is a large family of monocotyledonous flowering plants which are collectively referred to as grasses. It includes bamboos, cereals, grasses of natural grassland etc. It is an economically important plant family, providing cereals such as maize, wheat etc. Bamboo which is used as a building material belongs to the family Poaceae.

Poaceae, formerly called as Gramineae because it includes grasses. It is a large family of monocotyledonous flowering plants. Poaceae includes cereals, bamboos and grasses of natural grassland. It is an economically important family of plants, providing staple foods from domesticated cereal crops such as maize, wheat, barley etc. 

Jowar (Sorghum bicolor) belongs to the grass family, which is scientifically known as Poaceae (formerly Gramineae).

Wheat and Rice belongs to family Poaceae.  The scientific name of wheat is Triticum aestivum. 

Most orchids are epiphytes as they have epiphytic roots. Epiphytes are plants that grow anchored to other plants. They are non-parasitic. Epiphytic roots are adventitious roots found in the epiphytes. These roots are present in the air and absorb the moisture and nutrients from the air. Since epiphytic plants do not have roots in the soil, they are called as air plants. Epiphytic roots of orchids grow on the surface of other plants for getting shelter.
