ASIM Biology
Biology COS Objective 10
Introduction
In this lab, we will be studying
angiosperms. Angiosperms are
vascular plants (have water and
nutrient conducting structures)
that produce flowers, which
contain the plant’s reproductive
organs.
Within the flower, seeds will
be produced.
In angiosperms, seeds are
enclosed in a structure called
the ovary, which will mature
into a fruit.
There are four major floral parts:
a corolla -the collective name for the
petals, which are above the sepals and
are usually brightly colored and
sometimes scented to attract pollinators
a calyx -collective name for the sepals,
which are the leaf-like structures at the
flowers base to protect the developing
bud
stamen(s) - the male portion of a flower
pistil(s) - the female portion of a flower
A flower that possesses all 4 floral
parts is said to be a complete flower.
Additionally, flowers may be either
perfect (containing both stamens
and pistils) or imperfect (having
either stamens or pistils).
Parts of a Flower
http://urbanext.illinois.edu/gpe/case1/c1facts2d.html
Monocots
1 cotyledon
Floral parts in multiples of 3’s
Parallel venation pattern in leaves
Vascular bundles scattered in stem
Fibrous root
Examples: grasses, sedges, lilies,
orchids and onions.

Dicots
2 cotyledons
Floral parts in multiples of 4’s or
5’s
Netted venation pattern in leaves
Vascular bundles arranged in a
ring in stem
central taproot with lateral roots
and root hairs
Dicots include broadleaf trees, shrubs, most
flowers, and vegetables.

For the next few slides, view the
pictures and decide if the flower
shown is a monocot or a dicot!

Let’s review the parts of a flower again. Also, see if
you can identify some monocots and dicots.
