Green Algae's are the plant without body
They are mostly unicellular , conical, filamentous
They are Autotrophic because they contain
Green Algae's are found mostly in fresh water ,
So they are mostly aquatic.
The algae cell wall consist of two layers i.e.
cellulosic and other pectin compounds.
Reproduction in Algae
Vegetative Asexual Sexual
By the formation of
various types of
Motile or Non-Motile
The most common
being the Zoospores.
and on germination
give rise to new
Volvax is a genus of chlorophytes, a type of green algae.
It forms spherical colonies of up to 50.000 cells.
They live in variety of fresh water habitat.
Volvax developed its colonial lifestyle 200 million ago.
An asexual colonies includes both somatic(vegetative
cell) which do not reproduce , and gonidia which
produce new colonies through repeated division.
The daughter colonies have their flagella initially
In sexual reproduction two types of Gametes
Male cone release numerous
microgametes,while in female colonies single
cell enlarge to become oogamets,or egg.
Clamydomonas are the single celled alga.
It mostly grows in ponds, ditches and wet soil.
Reproduce sexually by producing Zygote.
Reproduce Asexually by producing Zoospores.
The zoospores grow into mature
haploid cells, completing
the asexual life cycle.
These daughter cells
develop flagella and
cell walls and then
emerge as swimming
zoospores from the wall
of the parent cell that
had enclosed them.
It reabsorbs its flagella and then divides twice
by mitosis, forming four cells (more in
A mature cell of Clamydomonas
is a haploid
When the zygote breaks) dormancy,
Meiosis produces four haploid
Individuals (two of each mating type)
That emerges from the coat.
This diploid zygote
secretes a durable
coat that protects
the cell against
They eventually grow into mature cells.
A mature cell of
Clamydomonas is a
Within the wall of the parent cell,
mitosis produces many haploid
Fusion of the
isogametes occurs slowly,
forming a diploid zygote.
After their release, gametes from
opposite mating types (designated
+ and - ) pair off and cling together.
Both reproduce sexually and asexually
Fast growth rates
High metabolic rates
Fast nutrient uptake
Occupy new spaces after disturbances
Spirogyra is a filamentous ribbon like
It is mainly found in fresh water.
It can be long up to 2 cm.
Cell Wall in spirogyra is made up of two
1)Outer layer is made up of pectin.
2)Inner layer is made up of
Ulva has marine habitat
The leaves of ulva is like algae.
It is a sea lettuce.
Ulva has no. Of leaves on one branch.
Asexual reproduction: Bi-flagellate zoospores
Gametophytes (1n) form biflagellate isogametes; fuse in
pairs -> germinate -> form sporophyte (2n).
Sporophyte cells undergo meiosis -> form quadriflagellate
zoospores (1n) -> release -> form the gametophytes (1n).
Sporophyte isomorphic to gametophyte except that it is
Life cycle of Ulva
In bryophytes body differentiation starts to
It is also called as plant amphibian.
Steam and leaf like structures are present on
Water is crucial for their existent.
Bryophytes are mostly found in hilly areas.
Specialize vascular tissues are absent.
They also have cryptogam like thallophyta.
They have erect portion.
The rhizoid may be unicellular or multicellular.
Rhizoid are hair like structure present on lower
In Asexual, reproduction takes place by
fragmentation or spore formation.
In Sexual, reproduction takes place by gametes.
Male plant is known Antredium & female plant is
Moss and Liverworts
Life cycle of Funaria
Mosses possess radial symmetry, through it may be erect,
hanging or creeping.
The plants are usually foliose.
Branching is lateral.
Rhizoids are multicellular and branched.
The sporophyte is always differentiated into foot, seta and
capsule and is more elaborate.
Seta develops fully before the maturity of cells.
Vascular tissues are absent.
Liverworts has leafy thallus.
A filamentous stage is absent. Plant is directly formed from
Rhizoids are unicellular.
Sporophyte may or may not be differentiated into foot, seta
Seta develops rapidly towards the maturity of spores.
Life Cycle of Fern
Phanerogame have distinct organs like root, steam,
Roots are present due to presences of special vascular
Reproductive part is visible in Phanerogame.
Phanerogame are classified on the basis of their type
Gymnosperms are soft wood plant.
Their plants are perennial, evergreen and
The leaves of gymnosperms are needled
They are branched or sometime
Leaves are simple or compound.
They are well adopted in extreme
Roots are of two types in gymnosperm- (a)Tap root
Reproduction is by Hetrospores.
Sporangia produces two types of spores.
1)Microspore- It is small in size and
germinates to give rise to male gametophyte
which produce male gametes.
2)Megaspores-It is the large in size and
germinates to give rise to gametophyte which
produces female egg.
Spores spiral are arranged in compact structure
called strobili or combes.
Their are 2 types of cone- Male cone, Female
Strobili (with microspores)
i. All these megaspores does not produce female
gametophyte only one of them produce female
ii. Male & female gametophyte do not have an independent
free living existence.
iii. They are not independent in their existence.
iv. Male or female cone can be present on same or different
Cycus is called living fossil as it posses many character of
It is an evergreen small palm-like or tree-fern like
They have symbiotic association with blue-green algae like
Nostoc, Anabaena etc.
Angiosperm are hard wood plants
The seeds of angiosperms are covered by fruits.
All the flowering plants are angiosperm.
They have broad leaves.
Angiosperm form the largest group from
Angiosperm are found anywhere in extreme condition also.
SINGIFICANES & ECONOMICAL USE
These are the primary food for all animals.
Provides o2 for breathing.
It also provides Lumbar & fibres for clothing.
It is used for drugs production.
Based on number of cotyledon present on it.
1)It is a structure or predesigned plant inside the enclosed
2)It is termed as seed leaves.
3)Their are variety which contain one or two seed leaves.
Monocots are the plants which bear one cotyledon.
There are one leaves at the nodes.
The vascular bundle in scattered.
In monocot floral parts is always multiple of 3.
Eg- Maize, Onion, Sugarcane etc.
Dicot plant bears two cotyledon in the seed.
There is two leaves at the node.
Vascular bundle in Dicot is ring like structure.
Floral parts in Dicot is multiple of 4 & 5.
Eg- Rose, Lotus , Mango.
