Basic Characteristics of Funaria

 

Habitat: – It is common moss and found growing at damp places.

 

Size: – Its size is half to an inch.

 

Structure:

It consists of three parts.

 

1. i) A vertical stem like structure.

 

1. ii) Leaf like photosynthetic structure.

 

iii) Multicellular rhizoids arising from the lower side. It absorbs water and salts.

 

Reproduction:

 

1. i) Male $ex organ (antheridia) is present at the tip branch.

 

1. ii) Female $ex organ (archegonia) is present at the tip branch.

 

Lifecycle:

 

1. i) Fertilization occur in archegonium in the presence of water.

 

1. ii) Embryo and then sporophyte develop into zygote.

 

iii) The sporophyte gets water, salts and food from parent plant.

 

1. iv) Sporophyte consists of Foot, Seta, and Capsule.

 

Alternation of Generation: – Funaria has well defined alternation of generation.

 

HapIoid gametophyte generation is dominant. Diploid sporophyte attached to and more less dependent on the gametophyte.

 

Now let’s compare the microstructure of e-ink screens with the screens of tablets (smartphones). This is how the structure of the e-ink screen looks under a microscope (reader screen O NYX B OOX Cleopatra 3 ): 4. Screen backlighting is possible only from above. Backlighting from below (through the screen) will not work, since, regardless of the pattern of the formed image, the light will pass through the same amount of both black and white pigments. 5. It will be very difficult to create an e-ink screen with a color image (since there are only two types of charge (positive and negative), and there should be at least four types of pigment (red, green, blue, black).
