Plant Lab
Name: ___________________
Instructions: You and your lab partners will travel from station to station examining different plant
structures and plant types. Pay attention to detail as you make your observations. You are to make
clear, detailed drawings.
Station #1: Vascular Seed Gymnosperm
Gymnosperms are vascular plants because they have roots, stems, and leaves. They evolved seeds
and the use of pollen grains in reproduction. The seeds are “naked” in that they are not enclosed in
an ovary like in Angiosperm but inside cones. The pollen grains are the male gametophytes that
develop into sperm. The pollen is able to travel through the air and dry environments, rather than
traveling through water as the seedless vascular plants or the nonvascular plants.

Questions: What is the purpose of the cone?
Station #2: Vascular Seed Angiosperm
Angiosperms are vascular plants because they have roots, stems, and leaves. They evolved seeds
and the use of pollen grains in reproduction. The seeds are enclosed in an ovary. The pollen grains
are the male gametophytes that develop into sperm. The pollen is able to travel through the air, and
by organisms carrying the pollen.
Drawing 1: Leaves of a
Monocot Angiosperm (show veins)
Drawing 2: Leaves of a
Dicot Angiosperm (show veins)
Questions: What makes monocots and dicots leaves different?
Station #3 : Angiosperm Seeds
Drawing 1: Seed of a
Monocot Angiosperm
Drawing 2: Seed of a
Dicot Angiosperm
Questions: What makes monocots and dicots seeds different?
Station #4: Angiosperm Reproductive Structures
(a) Observe the male reproductive structures – the stamens. Each stamen consists of an anther
and filament.
(b) Observe the female reproductive structures – the pistil. Each pistil consists of an ovary, a
stigma(“sticky”), and a style.
Draw and LABEL the reproductive structures of the flower – look at the picture guide to help.
Drawing 1: Male Part - Stamen
Drawing 2: Female Part - Pistil
Question: If this flower has petals arranged in 3’s, is it a monocot or dicot?
(hint: look at the leaves)
Station #5: Roots
Observe the 2 types of roots at this station. And draw them below.
Drawing 1: Carrot – Tap Roots
Drawing 2: Grass – Fibrous Roots
Questions: What is advantage of a tap root? What is the advantage of fibrous roots?
