Introduction

Gymnosperms

Gymnosperms are plants that produce naked seeds on scaly structure, named
strobilus or cones. Its sporophyte generation produces 2 types of spores:
microspores that will develop into male gametophytes and megaspores that
develop into female gametophytes which is nutritionally dependent on living
sporophyte. The four main phyla of gymnosperms are Cycadophyta,
Ginkgophyta, Coniferophyta and Gnetophyta.

EXPERIMENT 9: ANIMAL DIVERSITY – INVERTEBRATES AND
VERTEBRATES

Course Learning Objective: Conduct basic biology laboratory work on
diversity of living things, chloroplast in aquatic plant, homeostasis and
coordination by applying manipulative skills.
(P3, CLO 2, PLO 2, MQF LOD 2)

Learning Outcomes:
At the end of this lesson, students should be able to identify unique
characteristics of invertebrates and vertebrates.

Student Learning Time (SLT):

Face-to-face Non face-to-face

2 hours 0

Introduction

Animal classification is a matter of sorting out their similarities and
differences, and then placing them into groups. Among the most basic criteria
by which animals are sorted is whether or not they possess a backbone
(vertebral column). More than 90% of animal species found in the world
belonged to invertebrates.

Invertebrates

Invertebrates are multicellular animals without vertebral column. Many
invertebrates such as jellyfish or worm have a fluid-filled hydrostatic skeleton
that function as a support mechanism. Other invertebrates such as insects and
crustaceans possess hard outer shell for protection. There are different phyla
of invertebrates. The most common phyla of invertebrates include the
Annelida, Arthropoda, Mollusca and Echinodermata.

Vertebrates

Vertebrates are classified in the phylum Chordata. Members of the subphylum
Vertebrata comprise of animal with backbones and spinal cord.
Approximately 64,000 species of vertebrates have currently been described.
Vertebrata is the largest subphylum of Chordata, and contains many familiar

DB024 Lab Manual

groups of large land animals. Vertebrates are the animals from the groups of
jawless fishes, bony fishes, sharks and rays, amphibians, reptiles, mammals,
and birds. All vertebrates have the following characteristics during the
development stage:

(i) notochord
(ii) dorsal tubular nerve cord
(iii) pharyngeal slits present in early embryonic development
(iv) post anal tail

The above characteristics may undergo changes or diminish during the
embryonic development.

EXPERIMENT 10: CHLOROPLAST IN AQUATIC PLANT

Course Learning Objective: Conduct basic biology laboratory work on
diversity of living things, chloroplast in aquatic plant, homeostasis and
coordination by applying manipulative skills.
(P3, CLO 2, PLO 2, MQF LOD 2)

Learning Outcomes:
At the end of this lesson, students should be able to:
i. Prepare the slide of an Elodea leaf.
ii. Examine the internal structure of an Elodea leaf: the cell membrane,

cell wall and chloroplasts

Student Learning Time (SLT):

Face-to-face Non face-to-face

2 hours 0

Introduction.
Elodea is an excellent plant for our studies of photosynthesis and cells
because the leaves are only a few cells thick so they will be easy for us to
observe under the microscope to look at cells and cell parts.

Figure 10.1 Elodea sp.

DB024 Lab Manual

Figure 10.2 Cells of Elodea sp.

Figure 10.2 shows leaf cells of an Elodea sp. These living plant cells are
viewed by light microscopy.

With a microscope we can see the chloroplasts move around inside living
cells. Chloroplasts and the other living parts of the cells are found near the
cell wall, but not usually in the center of the cell. Since they contain
chlorophyll, which are green, chloroplasts can be seen without staining and
are clearly visible within living plant cells. However, viewing the internal
structure of a chloroplast requires the magnification of an electron
microscope.

slide.

2. Place one drop of fresh water onto the leaf, and carefully place the cover

coordination by applying manipulative skills.
(P3, CLO 2, PLO 2, MQF LOD 2)

2 hours 0

Introduction

Homeostasis is to maintain constant internal environment of the living
organism through physiological regulation. Various organs are responsible
for regulating different environmental variables. In human, heart rate and
temperature need to be regulated within certain set ranges. Hypothalamus for
example plays important roles in regulating body temperature through
negative feedback mechanism. When body temperature increases,
thermoreceptors will detect this changes and cause physiological adjustment
to bring the temperature back to normal range. Medulla oblongata likewise
plays the similar functions to regulate body pulses.

Student Learning Time (SLT):

Face-to-face Non face-to-face

2 hours 0

Introduction

Living organisms depend on the information obtained from the environment
for their survival. Most of the information about the environment detected by
the special sense organs called the receptor organ. These receptors receive
stimuli such as light, sound, temperature, taste and smell in the environment.

Although stimuli and sensory organs are different, the sequences of events
that occur in the receiving of stimuli are the same (see diagram). External
stimuli are received by the sense organs such as ears, eyes, nose, skin and
tongue. From sensory organs, the external stimuli are received by one or
more sensory neurons that become impulses. Sensory neurons have many of
the same character, but different from one organ to another organ that is
sensitive to a specific stimulus. Example: there are sensory neuron sensitive
to light and sensory neurons that are sensitive to vibration. Central nervous
system will translate these impulses and the information obtained is used by
the organism to react the stimulus.

Stimulus → Receptor organ → Neuron → Impulses transmit → CNS

Updated: 20/05/2020 45

In human there are two types of reflex, which are:tendon reflex and organ
