questo e un documento riassuntivo che permette di presentare l'argomento delle piante nella materia di botanica

1. Angiosperms:
Monocots and dicots
in comparison
Domenico Policastro Brancale • Matricola 17057

2. The body of the plant consists of:
,
● Bud
● Root system
Overview
Stems, leaves, flowers,
buds and fruits.
Main roots
and
ramifications

3. Plants belonging to the angiosperm family have characteristics
They produce seeds (protected)
They include both woody and herbaceous species
The cotyledons are limited

4. Monocotyledons and dicotyledons
Have important differences in the conformation of some elements:
Cotyledons Roots Vessels
conduct
Ribs Fiore
Monocots
Dicots
Monocots and dicots

5. Numero di cotiledoni
Angiosperms are divided
into:
Dicots Monocots
They generate
embryos with two
cotyledons
They generate
embryos with
only one
cotyledon
Number of cotyledons

6. Fusto (1)
➢ The conducting
vessels are dispersed
inside the stem.
➢ The conducting
vessels are arranged
in such a way as to
form a ring.
In monocots In dicots
A difference that is observed in the stems of both groups concerns the
Vessels conduct
Stem (1)

7. Fusto (2)
There are also differences in the stem as regards the
DIAMETER
Due to the activity of the
SECONDARY THICKNESS MERISTEM
Absent in
DICOTS
Present in
MONOCOTS
It allows to have a
constant diameter
They have an
irregular diameter
Stem (2)

8. Foglie (1)
One difference concerns the
RIBS
Dicots Monocots
what do they do?
They internally connect the
leaves with the rest of the
plant.
Reticulated ribs Parallel ribs
Several main ribs running
parallel
A main rib runs with lateral
ribs which branch out from it
Leaves (1)

9. Leaves (2)
The way in which the leaves connect to the stem depends
From their own group Monocots
Dicots
The petiole
is present in this group
The sheath
is present in this group

10. Roots
In dicots
Taproot roots
In monocots
Collated roots
Main functions common to
both groups
1. Anchoring the organism to the ground
2. Absorb water and minerals
3. Carrying nutrients
How are they formed? How are they formed?
They develop from a
main root which then
generates lateral roots
DIFFERENT KINDS
It consists of several main
roots that branch out to
form a dense cluster
