Lecture 1: Algae,Bryophytes, Pteridophytes, Gymnosperm

Draw labelled diagrams of
a. Female and male thallus of a liverwort.
b. Gametophyte and sporophyte of Funaria.
c. Alternation of generation in Angiosperm.

Lichen is usually cited as an example of ‘symbiosis’ in plants where an
algal and a fungal species live together for their mutual benefit. Which of
the following will happen if algal and fungal partners are separated from
each other?
a. Both will survive and grow normally and independent from each
other.
b. Both will die
c. Algal component will survive while the fungal component will die.
d. Fungal component will survive while algal partner will die.

With the help of a schematic diagram describe the haplo-diptontic life
cycle pattern of a plant group.

Gametophyte is a dominant phase in the life cycle of a bryophyte. Explain

The heterosporous pteridophytes show certain characteristics, which
are precursor to the seed habit in gymnosperms. Explain.

How far does Selaginella one of the few living members of lycopodiales
(pteridophytes) fall short of seed habit.

What are gymnosperms? What are its four classes?

Tabulate differences between Gymnosperm & pteridophytes

What are the two main classes of bryophytes?

Classify plant kingdom?

Describe the important characterslics of gymnosperms?

What is the difference between syngamy & triple fusion?

List any two differences’ between gymnosperms & angiosperms?

What are cone bearing plants called?

List any three characterstic features of Bryophytes.

Why some bryophytes are called liverworts.

Name a unicellular algae.

Differentiate between the following:- (i) red algae and brown algae (ii) liverworts and moss (iii) homosporous and heterosporous pteridophyte (iv) syngamy and triple fusion
