Our mission is to empower our students to utilize their potentials in a diverse and challenging world. We provide outstanding education for

the mind, spirit and body using state-of-the-art methodologies while fostering intercultural awareness, and lifelong learning.

General characteristics

of kingdom Plantae

 Nucleus: it is eukaryotic
 Cell wall: it consists of cellulose
 Cytoplasm: it contains chloroplasts

(green plastids) that contains
chlorophyll substance.

 Reproduction: the majority

reproduce sexually.

which algae were mentioned in the video?

Kingdom plantea is

classified into 3 groups

Higher algae

Phylum:

Rhodophyta

such as:

Polysiphonia

Phylum:

Phaeophyta

such as:
Fucus

Phylum:

Chlorophyta

such as:
- spirogyra

- chlamydomonas

the mind, spirit and body using state-of-the-art methodologies while fostering intercultural awareness, and lifelong learning.

1) Phylum Rhodophyta:

Example: polysiphonia alga

-They are marine weeds that consist of filaments sticking
together by a gelatinous coat

-Their cells contain chromatophores of red pigments.
So, they are called red algae.

2) Phylum Phaeophyta:

Example: fucus alga

- They are marine weeds that consists of simple or branched filaments.

- Their cells contain chromatophores of brown pigments.

So, they are called brown algae.

3) Phylum chlorophyte:

- Some of them are unicellular while others are multicellular.
- Their cells contain chloroplasts. So, they are called green
algea.

Example:
-Chlamydomonas alga (unicellular): it contains a cup-shaped
plastids
- Spirogayra alga (multicellular): it takes the form of unbranched filaments and its cell
contain spiral-shaped plastids.

Multiple Choice

All of the following is a difference between Chlamydomonas and spirogyra except .............

• the number of cells

• shape of algea

• shape of plastids

• the cell wall structure

Kingdom plantea is

classified into 3 groups

non-vascular

plants

Phylum:
Bryophyta
(Mosses)

such as:
-Riccia
Funaria

Our mission is to empower our students to utilize their potentials in a diverse and challenging world. We provide outstanding education for

the mind, spirit and body using state-of-the-art methodologies while fostering intercultural awareness, and lifelong learning.

They are plants that don’t contain vascular tissue which are specialized in
transporting water or food. So, they are called non-vascular plants and
represented by:

Phylum Bryophyta (mosses):

They are terrestrial plants that live in damp soil and shaded places,
because they need high dampness to grow and reproduce.

They are small-sized plants, green in colour and have hairs for
anchorage (rhizoids)

Examples: -Riccia which is flat.

-Funaria which is erect.

Kingdom plantea is

classified into 3 groups

vascular plants

Phylum:

Tracheophyta

class:

Angiospermae

(Flowering plants)

subclass:

Monocotyledonae

such as:

wheat, onion and

palm

subclass:

Dicotyledonae

such as:

Bean and cotton

class:

Gymnospermae

(Confires)

such as:

pinus

class:

Filicatae
(Ferns)

such as:

-polypodium

-adiantum

Our mission is to empower our students to utilize their potentials in a diverse and challenging world. We provide outstanding education for

the mind, spirit and body using state-of-the-art methodologies while fostering intercultural awareness, and lifelong learning.

2) Class Filicatae (Ferns):

Examples:
Polypodium

Adiantum

- They are simple-structured plants, where most of them are herbs and few
are shrubs or trees.

- They have stems, leaves and roots.

- They live in shaded-damp places, such as the walls of wells and shaded-
damp valleys.

- They carry pinnate leaves.

- They don’t produce flowers or seeds.

- They reproduce asexually by spores that are found in special structure on
the lower surface of leaves.

the mind, spirit and body using state-of-the-art methodologies while fostering intercultural awareness, and lifelong learning.

2) Class Gymnospermae
(Confires):

Example: pinus

- Most of these plants are trees and few are shrubs.

- They carry simple needle-shaped leaves.

- They carry male and female cones.

- They don’t form flowers (non-flowering plants)

- They produce naked seeds (without coat “pericarp”). So , they are
Gymnospermae

- They reproduce asexually.

Our mission is to empower our students to utilize their potentials in a diverse and challenging world. We provide outstanding education for

the mind, spirit and body using state-of-the-art methodologies while fostering intercultural awareness, and lifelong learning.

3) Class Angiospermae
(flowering plants):

They are terrestrial plants that have stems, leaves and roots.

They carry leaves with parallel or palmate venation.

They produce flowers that change into fruits which enclose the seeds.

They reproduce sexually.

They are classified into two groups (subclasses), which are:

Monocotyledons.
Dicotyledon.
