Plantae

Plantae are eukaryotic, multicellular organisms that contain chloroplasts and chlorophyll. They are characterized by being non-motile, autotrophic, multicellular eukaryotes that contain chloroplasts and chlorophyll for photosynthesis. Plants are classified into flowering plants and non-flowering plants. Flowering plants are further divided into angiosperms and gymnosperms, while non-flowering plants include thallophyta, bryophyta, and pteridophyta. The plant life cycle involves alternation of generations between a haploid gametophyte generation and a diploid sporophyte generation.

Plantae

Anthony, Kenny, Owain


Introduction
Plantae are eukaryotic, multicellular and autotrophic
organisms. The plant cell contains a rigid cell wall.
Plants have chloroplast and chlorophyll pigment,
which is required for photosynthesis.

Flowering plant Non-flowering plant


A plant that produces flowers, A plant which do not produce
fruit, and seed. flowers.
Example: Angiosperms and Example: Thallophyta,
Gymnosperms Bryophyta, Pteridophyta
Flowering Plants
Angiosperms
● seed-bearing vascular plants with a
well-differentiated plant body.
● The seeds of angiosperms are
enclosed within the fruits.
● Angiosperms are further divided
into monocotyledons and
dicotyledons according to the
number of cotyledons present in the
seeds.
● Examples: mango, rose, tomato, etc.
Differences Monocotyledon Dicotyledons
Embryos Have a single Have a pair of cotyledons
cotyledon

Root system Fibrous root system Tap root system

Leaves venation Parallel venation Reticulate or net leaf


venation

Flower counts Multiple of three or Multiple of four or five or


equal to three equal to four or five

Cambium Do no posses cambium Possess a cambium and


and cannot increase in can increase in diameter
diameter

Examples Garlic, onion, wheat Beans, apple, pear


Gymnosperms
● Have well-differentiated plant
body and vascular tissues
● Gymnosperms seeds are not
enclosed within a fruit.
● Examples: Cycas, Pinus, Ephedra
Non Flowering Plants
Thallophyta
● Includes plants with
primitive and simple body
structure
● The plant body is Thallus,
may be filamentous,
colonial, branched, or
unbranched
● Examples: volvox, Fucus,
Chara, etc
Bryophyta
● Do not have vascular
tissues
● Plant body has root-like,
stem-like and leaf-like
structures.
● Are terrestrial plants,
require water for sexual
reproduction
● Require water for sexual
reproduction.
Pteridophyta
● Have well differentiated
plant body into root, stem,
and leaves.
● Have a vascular system
for conduction of water
and other substance
● Examples: Selaginella,
Equisetum, Pteris
Life Cycle 03
Gametophyte
The gametophyte is the dominant life
phase in the Bryophytes. The gametophyte
produces structures known as antheridia
and archegonia, which produce the male
and female gametes respectively.
Sporophyte
Is a multicellular structure or generation in
the life cycle of a plant which possess diploid
cells or cells which two genomes or two sets
of chromosomes. It produces haploid spores
or meiospores through the process of
meiosis in its diploid cells
