- It is the biological process by which new "offspring" are produced from their "parent".
- Mode of reproduction that does not involve the use of gametes or sex cells.
- Mode of reproduction that involves the use of gametes or sex cells.
- It is a type of asexual reproduction involving the division of body into two or more equal parts. It is also called as "Binary _____".
- It occurs in prokaryotic microorganisms and in some vertebrate, multi-celled organisms. e.g. Paramecium
- It is a type of asexual reproduction where the body breaks into two or more parts, with each fragment capable of becoming a complete individual; in animals, it is usually followed by regeneration where the missing parts are produced.
- E.g. a lost arm of the starfish may be regenerated by mitotic cell division.
- It is a type of asexual reproduction where a new individual arises as an outgrowth (bud) from its parents, develops organ like those of the parent, and then detaches itself.
- It is occurring commonly in some invertebrate animals such as corals and hydras.
- It is a type of asexual reproduction where a new individual forms from an aggregation of cells surrounded by a resistant capsule or spore, which later on germinates.
- It is a form of asexual reproduction where an egg develops into a complete individual without being fertilized.
- It occurs in invertebrates such as water fleas, rotifers, aphids, stick insects, some ants, wasps, and bees.
- Bees use _____ to produce haploid males (drones) and diploid females (workers).
- It is a type of sexual reproduction involving the union of gametes from two genetically different parents.
- Gametes can be ______, it is the fusion of similar gametes which are usually motile-capable of movement or motion.
- Gametes can be _____, It is the fusion of dissimilar gametes.
- In _____, a large immotile of gamete, the egg is fertilized by a small motile gamete, the sperm.
- It occurs in animals where one individual has both male and female reproductive parts.
- Some invertebrates such as earthworms, slugs, tapeworms and snail are often _____.
- _____ may self-fertilize or may mate with another of their species, fertilizing each other and both producing offsprings.
- It is common in animals that have limited mobility or are not motile, such as barnacles and clams.
- It is a cell or organism that has paired or two sets of chromosomes, one from each parent.
- It is a cell or organism that has just a single copy of each chromosome.
- These cells are formed after mitotic cell division. It is often seen in somatic cells of various vertebrates.
- These cells are formed after meiotic cell division. It is observed in sex cells or gametes of various vertebrates.
- It is a unit of energy that indicates the amount of energy contained in food. It specifically refers to the amount of heat energy required to raise the temperature of 1 kg (2.2 lb.) of water by 1oC (1.8oF). The greater the number of Calories in a quantity of food, the greater energy it contains.
- serve as a major energy source for the cells in the body. These are usually obtained from grains, cereals, breads, fruits, and vegetables. On average, carbohydrates contain 4 Calories per gram.
- can also be used as an energy source but the body mainly uses these as building materials for cell structures and as enzymes, hormones, parts of muscles, and bones. Proteins come from dairy products, poultry, fish, meat, and grains. Like carbohydrates, proteins also contain 4 Calories per gram
- are used to build cell membranes, steroid hormones, and other cellular structures; also used to insulate nervous tissue, and also serve as an energy source. Fats also contain certain fat- soluble vitamins that are important for good health. Fats are obtained from oils, margarine, butter, fried foods, meat, and processed snack foods. They contain a higher amount of energy per gram than carbohydrates or proteins, about 9 Calories per gram.
