Reproduction & Development Review 2
Sperm cell
male
They come from 2 parents, so chromosomes mix, this is sexual reproduction.
29.
30. The development of different organs and tissues from the embryonic germ layers is called
(1.) ovulation (2.) menstruation (3.) cleavage (4.) differentiation
31.
32.
33. a. What kind of fertilization is taking place above?b. Explain why so many eggs are released during this process?
c. What kind of organisms use this process?
External fertilization
To increase the chance of fertilization
Aquatic organisms
34. Identify the process in the diagram on the left.
Incomplete Metamorphosis
35. The process in which insect species change their body shape form and become adults is known as
(1) mitosis(2) metamorphosis(3) meiosis(4) cleavage
36. An adaptation for reproduction in most terrestrial organisms is (1)vegetative propagation(2)internal fertilization(3)regeneration(4)mitosis
