PRE-ACTIVITIES/PRE-TEST
- The main advantage of asexual reproduction, in addition to its speed, is that it permits the
propagation of advantageous _________________makeups since the offspring are
genetically______________ with the parent.
- Sexual reproduction, on the other hand, permits______________ of traits to arise from the
contributions of multiple different ancestors.
- Certain plants produce body parts specialized for breakaway and dispersal that are known
as________________________
- In grafting, the plant that is to be asexually propagated is known as the__________; this is
attached to the______________, which may be little more than a root. It is important that
the two have their layers in contact with each other.
- The production of_______________ by the seed plants largely circumvents the
requirement found in ferns, mosses, and the like for________________ as a requirement
for fertilization
B. ANIMAL REPRODUCTION
- The type of reproduction in which an animal divides into several pieces and then each
piece develops into an entire new animal is called
_____Fragmentation_____
- In metagenesis there is an alternation of
______asexual & sexual generations______
- Parthenogenesis is a type of reproduction in which an unfertilized egg
___Develops into a new individual__
- An individual that can produce both eggs and sperm is described as
_____Hermaphroditism_____________
- A sex cell (either egg or sperm) is properly called a ______gamete______; a fertilized egg
is a _______zygote__________
Activity 2: Complete the table by listing the advantages and disadvantages of
asexual and sexual reproduction in plants and animals.

IDENTIFICATION: Complete the sentence by supplying with the correct word/words from the
word pool. Write the answers on your notebook.
A. PLANT DEVELOPMENT
1. In the grass seed, the cotyledon is a food-absorbing structure known as a ___Scutellum___.
2. The portion of the seedling below the cotyledons is known as ___Hypocotyl___. One of the
structures included in it is the future root, or ___Radicle__.
3. The root hairs form in the zone of __Maturation__ the growing root tip.
4. When the “hook” of a dicot seedling is exposed to light during germination, it reacts by
___Straightening__; the receptor substance that initiates this reaction is a pigment known as
___phytochrome__.
5. The growing nodes of embryonic tissue found at the shoot and root tips of a plant are its
__Apical Meristems_.
B. ANIMAL DEVELOPMENT
1. Movement of cells to form a tube such as the neural tube is an example of _Morphogenesis;
specialization of cells to form neurons or some other cell types is called _Cellular Differentiation.
2. The rapid series of mitoses that to as converts the zygote to a morula is referred _Cleavage_.
3. The cluster of cells that projects into the cavity of the blastocyst is the _Placenta_, _Embryo_,
__inner cell mass_; it gives rise to the __Embryo__.
4. The process by which the blastula becomes a three-layered embryo is called _Gastrulation_.
5. The tissue layer that gives rise to the nervous system is the __Ectoderm _; the germ layer
that gives rise to the lining of the digestive tract is the __Endoderm_.
