Question

To study the characteristics of spirogyra, agaricus, moss, fern. Pinus( either with male or female cone) and an angiospermic plant and give two identifying features of groups they belong to

Answer 1

Spirogyra (green algae):

Characteristics:

1. Spirogyra is a green alga having a filamentous, unbranched, multicellular and threadlike structure.

2. Each filament has a large number of rectangular (length being more than breadth) cells.
Agaricus (mushroom):

Characteristics:

1. Agaricus is a common, white, fleshy edible mushroom.

2. It grows in the rainy season on damp logs of wood, trunks of trees and decaying organic matter.

Funaria (moss):

Characteristics:

1. Mosses are commonly found growing in tufts on moist and shady walls, damp soil and on tree trunks.

2. The main plant body is a gametophyte (haploid) which is green, erect (1-3 cm high) and sparsely branched.
Dryopteris (fern):

Characteristics

1. Dryopteris is commonly found in shady and moist areas in tropical, subtropical and warm, temperate regions.

2. The plant body is a sporophyte (diploid) which is differentiated into roots, rhizome (underground stem) and leaves.

Answer 2

Characteristics Of Plant

Explanation:

Qualities of spirogyra  

• It is a solitary cell thick, round and hollow fiber, vile to contact green hued green growth.  
• It becomes extremely quick in water.  
• The fiber has cells joined start to finish.  
• It has winding formed strip like chloroplast henceforth it is named Spirogyra.
• Cell divider is unmistakably observed.  

Qualities of Agaricus  

• Agaricus is normally called mushroom.
• It is non-green. It has a stalk and top like structure with spores in it. The spores sprout to shape mycelium.
• The top on its lower sides has gills which bear spores.  

Qualities of Moss  

• Greenery plant develops in thick fixes in clammy obscure and cool spots during the blustery season.
• Plant body is separated into verdant shoot and rhizoids.
• These are multicellular, land and/or water capable plants.  

Attributes of Pine  

• Pine trees are regular in Himalayas, they are tall, funnel shaped, evergreen.  
• Vascular framework is all around created.  
• Trees are huge 30-50 m, trunk width up to 2 m. The leaves are needle like.  

Distinguishing highlights of the gathering:  

• The angiospermic plants have well-created root framework and shoot framework.  
• The plants bear blossoms, foods grown from the ground.  
• These plants are either dicotyledonous or monocotyledonous.
