|
Term
| Describe/draw a sperm and an ovary |
|
Definition
| A sperm is a small single cell with a head and a long tail. An ovary is a large spherical cell. These are also called sex cell or gametes. |
|
|
Term
| Describe the process of sexual intercourse for mammals that could lead to reproduction. |
|
Definition
| For reproduction to occur semen must enter the vagina from the penis. |
|
|
Term
|
Definition
| the action or process of fertilizing an egg, female animal, or plant, involving the fusion of male and female gametes to form a zygote. In mammals, it's the fusing of a sperm and ovum cells. |
|
|
Term
|
Definition
| the period during which an embryo/fetus develops |
|
|
Term
|
Definition
| male reproductive fluid that contains sperm |
|
|
Term
| Define asexual reproduction |
|
Definition
| the creation of offspring involving only one parent. the offspring are clones of the parent meaning they have identical DNA. |
|
|
Term
| Write down 2 disadvantages of asexual reproduction |
|
Definition
| offspring are clones of parents, so there is less genetic diversity - colonies of clones are more liekly to be wiped out by environmental changes - parents do not care for offspring as much so the offspring are more likely to survive |
|
|
Term
| write down 2 advantages. of asexual reproduction |
|
Definition
| one parent can often have many offspring. - the colonies formed can often outcompete other organisms in the same ecosystem. - Energy is not required to find mates. |
|
|
Term
| Write down 2 disadvantages of sexual reproduction. |
|
Definition
| - More energy is required to find a mate (and sometimes engage in the act of sex). - Fewer offspring are produced, in general, than asexual reproduction. |
|
|
Term
| write down 2 advantages. of sexual reproduction. |
|
Definition
| more protection is given to the embryo and possibly the young offspring, so the offspring are more likely to survive. - offspring are genetically different from parents, so the species will have more genetic diversity and be more likely to sruvive in an environmental change. |
|
|
Term
| Describe division and growth of a human embryo. |
|
Definition
| The embryo starts as one cell. It divides again and again to become, 2, 4, 6... At 32 cells, the cells start to differentiate, or become different. Some cells are destined to become organs, others are destined to become placenta. Over time, the embryo will take on human form having limbs and all the organs. Then it is called a fetus (or a baby). |
